[meteorite-list] 1.4kg Tamdakht individual with find documentation - AD
Dear all, Available for sale is a 1407g complete individual of the Tamdakht meteorite fall from December 20, 2008. The meteorite is of triangular shape and has five surfaces crusted with rich primary fusion crust. The highly aesthetic specimen shows large, shallow but well developed regmaglypts. Along the edges of the impacting suface several small patches of crust chipped off. The surface leading during the final stage of the fall shows distinct impact marks. Of course the meteorite is uncleaned. This is one of the very few finds of the Tamdakht fall that were documented in situ. In situ photos of the impact situation and the meteorite itself can be seen here: http://www.meteorite-recon.com/en/meteorite%20tamdaght%205.htm The price is 2 EUR/g plus shipping. I am offering this stone on behalf of the owner. Thanks for your interest and the opportunity to post here.

[meteorite-list] West Texas: First Fall Meteorite! 6.7g
Hi all, After much research, driving, searching, collaborating and with a little help from some very cool meteorite hunters and nice landowners, we've found our first stone from the newest meteorite fall in the world! There are a few firsts here. First Meteorite Fall Chased First Meteorite Expedition First Time Driving 1500 miles (to chase rocks no less...) ;) Our first meteorite find from fall to find all within 10 days. I want to thank everyone who has helped us out here, you know who you are and we very much appreciate the cordial and helpful nature of everyone out here in West. The landowners have been more than gracious to let us hunt for meteorites on their land and many are characters and now hunt meteorites themselves. ;) We've hunted with a lot of you guys here from the list who a fortunate enough to be able to hunt this fall and we are truly grateful for your help and advice. Who better to learn from than the ones who do it day after day. Thank you! So without further ado - because I know you guys are itching to see the photos- here's my daily West Texas Meteorite Expedition Journal Entry and the photos of my first new fall meteorite, all 6.7 grams of it: http://www.meteoritesusa.com/blog/meteorite-photos/texas-meteorite-expedition-67g-meteorite-find/ In the meantime...

[meteorite-list] Ash Creek meteorites being found in West, Texas
Hello list members, Many of you meteorite hunters in West, Texas are finding stones that are broken exposing interior matrix. I know my son Patrick who is there hunting with Steve Arnold, Rob Wesel, Jason Phillips, Mike Bandli and a number of others is having a blast with everyone. Patrick has had great success in finding small stones and today I received a package from him with a very nice half stone in it that weighs 20 grams. The broken surface is very fresh and yet there is staining that looks like halos of rusting around metal flecks but is more like to be the rust colored staining that sometimes appears around some of the sulfides. I am writing to ask each of you successful hunters to take a close look at the broken surfaces on any of your fresh found specimens (preferably with magnification) to see if you can find any blueish or purple colored translucent crystals in the matrix. There might be halite in this meteorite which would be scientifically very important. I talked with Alan Rubi n about this today. He said that he had not looked for it in the piece that Rob Matson had brought for classification. Please drop me a line at etmeteori...@hotmail.com or at 503-701-3657 if you think you have found halite crystals in your fragmented specimens of Ash Creek from West, Texas.

Re: [meteorite-list] More damage (than the Pellisons)... Help!
Hi Mike and list, the Pellisons, I doubt that they have any remarkable effect, they are nobodies and they are private persons. Endless more harmful are articles like these, where in the perception of the readers, people of an official status are spreading their false pretences. Here for example they read: Caroline Smith, curator of the meteorite collection of London's Natural History Museum, and of course they suppose, that the - sorry - the rubbish, she's telling has to be true, and furthermore it was an article from holy BBC. They can't know, that Smith is relatively new in her job, so that she probably hasn't yet the clue, that ALL of her antecessors purchased the main load of the meteorites in her museum from meteorite dealers and from private collectors and persons - and that they had to pay much, much, much higher prices than what meteorites do cost today; and that she is not able to get her stats right and to use, like everyone else the Meteoritical Bulletins or the Bulletin Database. http://kuerzer.de/lousyPropaganda Read But Ms Smith is worried that the craze for meteorite collecting is having a damaging effect on scientific research. 'The commercial value of meteorites has now been realized, she says. It has affected our work because we are now competing against private collectors to obtain material for our research.' Excuse me, 80 or 90% of the meteorites in the London Nat.Hist. stem from private persons, dealers, collectors. In 1810, curator Koenig purchased the mineral collection of Charles Greville for more than 1 million USD (today's money), Parish donated them a 3.5 ton-Campo, Curator Maskelyne bought like a fool to rival Vienna, of course from dealers and privateers too, more than 200 locales, and most of these specimen he bought from the mineral (and meteorite) dealer August Krantz (1809-1872, a famous Pultusk-looter). Next curator Fletcher was known to be a tough negotiator in buying meteorites - the seller had to tell the price, not he. And famous is the anecdote, when Fletcher bribed the niece of the owner of Crumlin in buying her an organon, for her to convince her uncle to sell that meteorite. (Well, from the last Crumlin we sold to an Irish museum, we hardly could afford a good keyboard). Well and then later curator Hey had a simple maxim about meteorites: Get it, keep it. And in 1959 he bought a part of the collection from the well-known meteorite dealer Harvey Nininger. Some say it was half of the collection, some sources tell a third, some a fifth. (Maybe the discrepancies are because some counted the different locales, some the number of specimens, and some the weight). And he paid more than 1 million of today's USD. These were only some major purchases, and an excerpt from RusselGrady's History of the NHM meteorite collection. Maybe Mr.Smith should read it - and if she will go one day into the archives, she will find what their antecessors had to pay and wherefrom they purchased. In the same article: Sadly, many collectors and so-called entrepreneurs have recently noticed the marketable value of meteorites, and taking advantage of the poverty in some countries and the lack of education regarding the value So please Ms. Smith return the nice slice of DaG 262, which is highlighted on the BMNH pages, to the poor people of Libya. http://kuerzer.de/corpusdelicti Btw. what had the BMNH paid for that slice or what did they gave for material in exchange? (and tell to your colleagues of the Smithonian, which is mentioned in the end of the article to return their 5 specimens of DaG 262 too). Btw, when did BMNH acquire that slice? I remember the prices of the 90ies for DaG 262 and 400. 200,000$ a gram. Yes the meteorite prices have soared and now the dealers have realized the commercial value, cause today you can buy such material ar 500$ a gram. And if we are already occupied with house-cleaning, return the SaU 005 pictured below the DaG 262 to the government of Oman, because you have no export permit. (Why? Because nobody had the idea, that such stuff would need an export permit, cause nobody was interested in meteorites there.) Mr.Smith says: It has affected our work because we are now competing against private collectors to obtain material for our research. Yah. Private meteorites activities had an effect on research: The number of meteorite finds and falls outside Antarctica was growing from 3000 of the 200 years before to 13,000 in roughly one decade. Samples of all of them were given for free to the institutions, enriching and diversifying the institutional collections. Private people multiplied the tkws of historic finds and falls in recovering more pieces and some of the new observed falls wouldn't have been found at all without their work. Those finds became readily available to all scientists. The rare types among them outnumber the rare types found in Antarctica. And Mrs. Smith, the prices for that material are a fraction of these paid the 200 years

Hello list members, we are very sorry to have missed all of you at the Tucson Gem and Mineral show this year. Patrick and I will be back next year and we are planning to share our room with Keith and Dana Jenkersen to cut down on the cost of doing Tucson. I have a leg injury from 36 years ago that needs repair. The procedure is costly but doctors say that recovery means at least 6 to 9 months laying flat with the leg elevated. So it’s the time off that will really cost the big bucks. As a result we are selling some high profile specimens and personal collections that will help afford this time off. Most of these items will be listed on EBay. Included in the offerings is the meteorite book collection. The library collection has grown more extensive in recent years adding several classics including a first edition Chladni. The price for this offering is lower than ever with a ‘Make Offer’ feature. If the book collection doesn’t sell then we will sell them individually on our new web site meteoritebooks.com. Please look for that site opening soon. Also being offered for sale on Ebay for the first time is the entire Edwin Thompson meteorite thin section collection. This collection should be attractive to universities and other research institutions as well as private collectors and dealers. The slides are rectangles but any or all can be easily polished into rounds (as needed for probe stages). There are 1000 thin sections in the collection. It is featured on EBay right now. Please write if you have any questions or to request a complete list of any collection. Again, if this collection does not sell on Ebay then the slides will be offered individually on our soon to open site; etmeteorites.com. Thanks very much to everyone in Tucson who signed the card that Fred Olsen sent from Tucson. It was really fun to get and we got lots of laughs from everything said on the huge card. Thanks to all who wrote emails or called by phone. All of the pictures sent made it feel like we were there. It is s nice to know that we are missed for our nightly marguerites, ha! Hope to see you all next Tucson show on two good legs. Cheers, Edwin P.S. Patrick is in West, Texas hunting and finding meteorites right now and for the next three days.

[meteorite-list] Fireball Sighting Over Massachusetts
http://www.ack.net/022609fireball.html Fireball sighting maybe a meteorite By Eliot Baker The Inquirer and Mirror (Nantucket, Massachusetts) February 26, 2009 Island residents are being urged by Maria Mitchell Association director of astronomy Vladimir Strelnitski to keep their eyes open for meteorites around Surfside and the south shore in the coming days following an unconfirmed sighting of a fireball blazing across the early-morning sky Friday, Feb. 20 at 4:30 a.m. Terry Galschneider was up early watching television when she said a dramatic orange fireball lit up the sky for five seconds. She said the fireball was too large and bright to have been a shooting star or a helicopter. Her full description to Strelnitski left him to not exclude that it fell in the ocean, but maybe even on land. The object's brightness suggests it would be relatively close to Galschneider, although its lack of sound made that even less possible to tell for certain. He said it was highly unlikely to have been debris from colliding satellites. The sighting was not confirmed by either Nantucket airport officials or by the police, and no other reports of fiery objects in the sky Friday in Massachusetts have been made to NASA, or to astronomy departments at Boston University, the University Massachusetts at Lowell, or the American Meteor Society. Other islanders who may have spotted the fireball are encouraged to contact Strelnitski at the Maria Mitchell Association at (508) 228-5273. Though unlikely, Strelnitski said discovering a meteorite - or part of one - on Nantucket would be unprecedented and could yield important information to scientists. People around Surfside especially are encouraged to look for unusual small craters with valleys on the surface with strange objects inside. Meteors can be a piece of metal, a greenish or grayish piece of stone, or a black piece of organic matter that resembles coal called carbonatious condrite, the rarest of all meteorites. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] 'Dinosaur-killing' Impact Did Not Start Global Wildfires
http://www.nature.com/news/2009/090223/full/news.2009.112.html 'Dinosaur-killing' impact did not start global wildfires Burnt oil and gas, not vegetation, may have caused the soot layer at the end of the Cretaceous period. Philip Ball Nature Magazine February 23, 2009 Meteor impactThe impact thought to have wiped out the dinosaurs may not have led to global wildfires.NASA The impact of a huge asteroid or comet at the end of the Cretaceous period 65 million years ago is generally held responsible for the sudden demise of 60â80% of all species on Earth. But new results challenge the common idea that the extinctions were partly caused by global wildfires triggered by the violent impact. Claire Belcher and colleagues at Royal Holloway University of London in Surrey, UK, say in a paper in the Proceedings of the National Academy of Sciences USA that the widespread soot deposits in sedimentary rocks formed at the time of the putative impact are not, as previously asserted, evidence of runaway fires caused by the meteorite's impact. They have analysed the mixtures of carbon-based molecules called polycyclic aromatic hydrocarbons (PAHs) in the sooty material from these rocks, and find that the compositions of the mixtures don't match those typically produced by burning vegetation. Instead, they resemble those formed when hydrocarbons such as gas and oil are burnt. Burning issue The researchers think the soot comes from combustion of hydrocarbons within the rocks of the impact site itself - thought to be the region around Chicxulub on the north coast of the Mexican Yucatán peninsula, where a now partly submerged crater about 180 km across has been dated to the time of the mass extinction that separates the Cretaceous from the Tertiary period. A global layer of soot in rocks of this age was discovered in the late 1980s, and was interpreted as showing that the heat of the impact ignited wildfires all over the world. According to this hypothesis, vast swathes of land plants went up in flames, possibly roasting many animal species including the dinosaurs. But for several years now, Belcher and her colleagues have been casting doubt on the idea that the Earth was engulfed in flames for years after the impact. In 2003 they reported that rock strata in North America dating to the Cretaceous-Tertiary boundary showed little evidence of charcoal, which would be expected to be produced from burning vegetation. Instead, they speculated that the soot in these layers came from combustion of hydrocarbons. Now the team claim to have clinching proof of that: chemical fingerprints of the source of the soot, in the form of 21 different PAHs separated and identified using the technique of gas chromatography. Belcher says the new results also answer criticisms of their earlier work on the apparent lack of charcoal in the soot. Some other researchers have suggested that the wildfires might have been too intense to leave any charcoal. But Belcher says the PAHs she finds have molecular structures characteristic of relatively low-temperature formation. Ashes to ashes Nevertheless, she and her colleagues could still have some persuading to do. Bernt Simoneit, an organic geochemist at Oregon State University in Corvallis, questions whether the proportions of different PAHs in combustion products are a sufficiently discriminating signature of the fuel source. He also says that sources of petroleum hydrocarbons at shallow depths are very scarce now or in past times, and that the biomass of vegetation far surpasses the amount of near-surface oil. Belcher and colleagues, however, point out that Chicxulub is very close to Mexico's largest oil reservoir, the Cantarell Field. Regardless of where the soot came from, it seems clear that huge amounts of it were thrown into the atmosphere by the impact, blocking out sunlight and perhaps triggering global cooling - causing an 'impact winter'. The soot itself undoubtedly had a significant impact on life at the time, but it is unlikely to represent the signature of global wildfires, says Belcher. She says there are clear signs that plant life was severely disrupted, but that this might have been due to the heat of the impact fireball and the global darkness, cold and poisoning (from toxic products of burning hydrocarbons) that might have followed. I think that the global wildfire idea is beginning to be doused, she adds. Corrected: In an earlier version of this story we incorrectly stated that a meteorite impact caused the mass extinctions at the end of the Cretaceous period. References 1. Belcher, C.

[meteorite-list] Another Meteor Impact Coincides with Large-scale Volcanic Eruptions
http://planetearth.nerc.ac.uk/news/story.aspx?id=332 Another meteor impact coincides with large-scale volcanic eruptions PlanetEarth oinline 23 February 2009 Scientists have long debated the cause of the dinosaurs' extinction about 65 million years ago. The remnants of a large volcanic eruption in the Faroe Islands. These eruptions can go on for millions of years. Around this time a giant meteorite struck the Gulf of Mexico. But the extinction also seems to coincide with massive and long-lasting volcanic eruptions in India known as the Deccan Traps. So which event was responsible? And are these phenomena linked? New research now shows that this combination of meteorite impact and large-scale volcanic activity - known as flood basalt eruptions - is not unique. An international team of researchers looked at a 30-million-year-old meteorite crater in Belarus called Logoisk. They found that this too coincided with volcanic eruptions further south which covered Yemen and Ethiopia with basalt rock. These events are similar to those that occurred 65 million years ago, but on a much smaller scale. The scientists suggest such coincidences maybe more common than previously thought. Dr Sarah Sherlock from the Open University and lead author of the paper, says, 'If you have a flood basalt then people wonder if there's also an impact.' 'There will be, almost certainly,' she added. According to the paper, a meteorite will strike the Earth and leave a crater the size of Logoisk on average once every 1.5 million years. Flood volcanic eruptions occur over several million years, so a Logoisk-sized crater is likely to occur during each of the 16 identified periods of flood volcanism on Earth in the last 360 million years. However, researchers do not think there is a causal link between flood volcanism and meteorite impact. 'There is simply no geological evidence to link the two,' says Sherlock. To determine the precise age of the Logoisk crater the researchers used argon dating. 'Argon dating is very versatile.' said Sherlock. 'It's the only technique that can be used to date both [impacts and flood volcanism].' Samples of material from the crater were gradually heated using an infrared laser, causing the release of argon gas. The ratio of two isotopes of argon released in the gas gives an accurate indication of the age of the sample. Using this technique, the researchers showed that the two events occurred simultaneously. One question raised by the results was why the meteorite impact and flood volcanism 65 million years ago wiped out much of life on Earth, including the dinosaurs, but the similar events 30 million years ago did not. According to Sherlock, it was down to the size of the events. 'These coincidences in Earth's history are not as rare as people think, but in order to actually do significant damage to the environment they have to be really, really big.' Sherlock added. Together, the 65-million-year-old Chicxulub crater in the Gulf of Mexico and volcanic eruptions that produced the Deccan Traps eruption 65 million years ago released 8000 gigatonnes (Gt) of sulfur dioxide, causing global environmental damage. By comparison the Logoisk and Afro-Arabian events released only 30Gt - insufficient to cause change on a global scale. The research is published in the Journal of the Geological Society, London. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

Re: [meteorite-list] More damage (than the Pellisons)... apologies
Good evening again, I was informed that in the linked BBC-articles, Ms Smith was misquoted and that her comments were reported out of context. That possibility I should have considered, therefore I have to apologise to her. Nevertheless, the recent developments I see with great worry. I'm not able to detect any vantages, if meteorite trade or searching will be restricted. That opposition private collecting/commercial trade versus research/museums, which is tried to be established - doesn't meet the reality, neither history and is highly artificial. Cause what are and were the requirements, why in former times they tried to protect meteorites: Science and institutes want more meteorites, they want more significant material and they don't want to pay much for it. Well and exactly these requirements were fulfilled by the private sector during the last ten years. The number of finds exploded, rare types became available in quantities and qualities like never before and the prices entrenched themselves under sea-level. Well and those countries bothering about meteorites could leave the country - for them it's cheaper to buy their meteorites than to equip official expeditions to find them and many, many more are found, as if they try it by their own. (Change the laws, let the Russian in, and you won't have less than 1 find, but 100 new Australian finds per year.) So I don't get it, where they see any problem. And I hope that the experiences made with such restrictive laws from such countries, where they do already exist, won't be ignored. I'm sorry. I'm old-fashioned, my first meteorite I got as a boy almost 30 years ago. It causes harm to me, to see that the great collections don't take part in the Golden Age of meteorites, be it because of the complete reduction of their budgets, be it of the misapprehension about the legal status of the NWA-material. One could get the impression, that it isn't a fantastic and welcome circumstance that so many new finds were recovered in these few years, but rather a huge displeasure? Would everyone be more happy, curators, collectors, scientists, the protectionism-group, the involved countries, if never any meteorite would have been found in Sahara and Oman? It almost seems so...

Hi List and Martin! Well said! I bow to you sir! Once again, your mastery of facts and history sets the record straight. The next thing you know, they will be blaming war and starvation on meteorite collectors. ;) Thank you Martin for the lucid and enlightening rebuttal of that article's nonsense.

Endless more harmful are articles like these, where in the perception of the readers, people of an official status are spreading their false pretences. Here for example they read: Caroline Smith, curator of the meteorite collection of London's Natural History Museum, and of course they suppose, that the - sorry - the rubbish, she's telling has to be true, and furthermore it was an article from holy BBC. They can't know, that Smith is relatively new in her job, so that she probably hasn't yet the clue, that ALL of her antecessors purchased the main load of the meteorites in her museum from meteorite dealers and from private collectors and persons - and that they had to pay much, much, much higher prices than what meteorites do cost today; and that she is not able to get her stats right and to use, like everyone else the Meteoritical Bulletins or the Bulletin Database. http://kuerzer.de/lousyPropaganda Read But Ms Smith is worried that the craze for meteorite collecting is having a damaging effect on scientific research. 'The commercial value of meteorites has now been realized, she says. It has affected our work because we are now competing against private collectors to obtain material for our research.' Excuse me, 80 or 90% of the meteorites in the London Nat.Hist. stem from private persons, dealers, collectors. In 1810, curator Koenig purchased the mineral collection of Charles Greville for more than 1 million USD (today's money), Parish donated them a 3.5 ton-Campo, Curator Maskelyne bought like a fool to rival Vienna, of course from dealers and privateers too, more than 200 locales, and most of these specimen he bought from the mineral (and meteorite) dealer August Krantz (1809-1872, a famous Pultusk-looter). Next curator Fletcher was known to be a tough negotiator in buying meteorites - the seller had to tell the price, not he. And famous is the anecdote, when Fletcher bribed the niece of the owner of Crumlin in buying her an organon, for her to convince her uncle to sell that meteorite. (Well, from the last Crumlin we sold to an Irish museum, we hardly could afford a good keyboard). Well and then later curator Hey had a simple maxim about meteorites: Get it, keep it. And in 1959 he bought a part of the collection from the well-known meteorite dealer Harvey Nininger. Some say it was half of the collection, some sources tell a third, some a fifth. (Maybe the discrepancies are because some counted the different locales, some the number of specimens, and some the weight). And he paid more than 1 million of today's USD..

[meteorite-list] 'Dinosaur-killing' Impact Did Not Start Global Wildfires
Hi Ron - Did Morrison referee this one? http://www.nature.com/news/2009/090223/full/news.2009.112.html The impact of a huge asteroid or comet uhhh - the impactor is known to have been a comet, and that has been known for quite some time. at the end of the Cretaceous period 65 million years ago is generally held responsible for the sudden demise of 60???80% of all species on Earth. But new results challenge the common idea that the extinctions were partly caused by global wildfires triggered by the violent impact. Claire Belcher and colleagues at Royal Holloway University of London in Surrey, UK, say in a paper in the Proceedings of the National Academy of Sciences USA that the widespread soot deposits in sedimentary rocks formed at the time of the putative impact are not, as previously asserted, evidence of runaway fires caused by the meteorite's impact. How about soot from the comet itself? The researchers think the soot comes from combustion of hydrocarbons within the rocks of the impact site itself How about soot from the comet's hydrocarbons? However you work the dynamics of the KT impact, you end up with a rain of molten impact debris which was perfectly capable of setting the surface of the Earth on fire. I suspect this team's measurement or laboratory techniques. E.P.

[meteorite-list] Comet Lunin - a heads up.
Hi to all, Anyone else out there check out Comet Lunin. Even through my pee shooter (Meade ETX-90/EC) of a telescope, the comet is quite clear in the dark Arizona skies. It is located between Saturn and Regulus. Regulus is the bottom star in Leo. Go outside and look to the southeast. I needed binoculars to locate it, then the telescope brought it in quite clearly. For those with larger telescopes, you may be able to actually see its green color. I envy you.

[meteorite-list] A Message Form Rob Wesel
Hello all Unfortunately the email account I use for the Met-List is not accessible from the field so I am writing through one our hunting team members and fellow Met-Lister Mike Bandli's account. It's been an awesome time here in west, exhausting but it will be remembered as one of my fondest life experiences. More will come later but I want to jump in and extend a thank you to Ruben Garcia and Sunny for their help in acquiring the Hopper Stone To those who have voiced concern, Hopper is being treated very well for his amazing hunting abilities. Landowners have been accomodating, food is awesome, and sleep comes easy at the end of a 13 hour day hiking uneven terrain over the course of 15-20 miles. Hopper has become fast friends with all the hunters out here. As I said, much more to come when I get back home.

[meteorite-list] Thursday West, Texas hunt
Well, another day has passed and for the second time, I got skunked. However, the rest of my friends did quite well. Robert Ward found one of the largest stones of the West fall yet. You likely saw todays pic of the day by Michael Johnson. Thanks Michael, for letting me send Iphone photos from the dirt to computers around the world in seconds. More hunters are showing up, and I am trying to get everyone who comes a stone. Call or meet me and I will show where all the stones are being found. It seems that there are others here who do not want to let anyone hunt with them, and that is not my style. We were nice enough to even announce that the meteorite had been discovered as Doug and Dima had no plans to do so per the landowner's wishes. We felt that more boots on the ground would lead to many stones recovered, we were correct. No problems with our team, we will hook you up. In fact, I will likely post a google earth map of all 60 or 70 stones I have mapped. I plan to coordinate with over 10 hunters and have already done so, but the map is a couple days behind as we are all very tired each night. Of course, we will not be able to include the other team's information as they are bound by secrecy laws and contracts not to speak about their finds. anyone needing information on the ground can get with me.

Re: [meteorite-list] 'Dinosaur-killing' Impact Did Not Start GlobalWildfires
Hi, EP, List, The very best part of this junk is the correction posted at the end of the news piece. I quote: Corrected: In an earlier version of this story we incorrectly stated that a meteorite impact caused the mass extinctions at the end of the Cretaceous period. Well, that's a big relief... It's very reassuring to know that getting whacked with a 10 to 15 mile diameter impactor won't actually extinct anything. Since this kind of event doesn't cause extinctions, why does it matter if it caused vegetation fires or oil fires? If the impact did no harm, why even bother to argue about it? A man is found dead in a locked room with another, living man. The live one is holding a recently fired pistol. The dead one has a recent bullethole in his forehead and a fresh bullet in his brain. The body is still warm. Did anyone see the living man shoot and kill the now-dead one? Forensics say the bullet in the brain came from that gun; the gun has the living man's prints; his hand has gunshot residues. Oddly, the gunpowder contained iridium... But nobody saw the accused pull the trigger. Nobody saw the bullet leave the gun or strike the victim. Nobody heard the shot. Nobody saw the victim fall dead. Case dismissed... for lack of evidence. Besides, those bullets don't really kill anybody, you know. Sterling K. Webb --- - Original Message - From: E.P.

[meteorite-list] Meteorite Hunting, Texas Style
Dear Listees: Greetings to all from the planet's newest strewnfield. I have not been posting reports partly because we've been working twelve hours a day in the fall zone, and partly because my policy is to spend field time in the field and then compile visuals when I get home. The West, Texas hunt has been a fabulous adventure and I am privileged to have been part of a team that included some of the best meteorite hunters in the world. We have great stories and photos and will be sharing them with you shortly. As a teaser, Rob Wesel was the star of the day, but I'd prefer to let him share his news with the List. Really, it is even better than Park Forest.

[meteorite-list] West, Texas: Two Firsts
Dear Listees: Hearty congratulations are due to two members of our team who found their first meteorites on this expedition: Patrick Thompson (E.T.'s son) and List member Mike Bandli both found their first-ever meteorites while on the ground with our gang. Mike will, I'm sure post details when he gets home. Patrick stunned everyone by going on to find more stones than some of the pros. Definitely a force to be reckoned with in the future. It was a treat to see these gentlemen pull their first-ever space rocks out of the dirt. And a witnessed fall to boot! And that's really it for tonight.
