Lots of Triassic Themed Presentations at the Annual Geological Society of America Meeting

What can I say, the Triassic is hot right now especially dinosaur origins and the Late Triassic of the American Southwest (of course temnospondyls and marine reptiles always seem to be happening). On Monday I pointed out that over 60 presentations at this years annual SVP meeting dealt with the Triassic. Now the abstracts for the 2009 annual meeting of the Geological Society of America are available online. Again quite a few Triassic presentations. The hot topics for that meeting appear to be the Triassic/Jurassic transition, and U-Pb dates for the Chinle Formation. There is quite a debate growing between those who accept the recent hypothesis of a long Norian (with all of the Chinle being Norian in age) and those who favor the traditional Carnian-Norian split of the Chinle. You can read some of my thoughts on this here and here.
