Re: [meteorite-list] Volcanoes, Not Impacts, Caused End Triassic Mass Extinction
Hi Paul - May I suggest looking for a large impact event as the trigger of those volcanic eruptions? It has been known to happen. good hunting,everyone - Ed __ Visit our Facebook page https://www.facebook.com/meteoritecentral and the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list
