[QUOTE] Other paleontologists, however, believe that the very proximity of El Peñón to the impact site makes the results not more reliable, but less. Earthquakes and tsunamis that resulted from the collision could have wrought havoc on the sedimentary record, causing discrete strata to swirl together and completely scrambling timelines [/QUOTE]
I'm no geologist but as I was reading this article I was thinking the same thing. I've seen computer recreations of the impact (on Discovery) and it completely liquefies the area of impact. I can see that screwing with timelines. According to the article they say that this asteroid hit and life thrived for another 300,000 years? [QUOTE] They conducted surveys at numerous sites in Mexico, including a spot called El Peñón, near the impact crater. They were especially interested in a 30-ft. layer of sediment just above the iridium layer. That sediment, they calculate, was laid down at a rate of about 0.8 in. to 1.2 in. per thousand years, meaning that all 30 feet took 300,000 years to settle into place.
