Permian Maps

Dr Ron Blakey has an interesting set of paleogeography maps of the world and especially NorAm. These are interesting to constrast with Dr Scotese's.

The Permian globe.

NorAm's Permian Geography

The PT Boundary in the SW US:

Now you know where to go hunting for potential Permian-Triassic Boundary sequences. I'd be itching to see if there are any terrestrial vertebrate - especially therapsid - fossils to be found in the sequences. NorAm at the time was close to equatorial, iirc, and theories state it would have been hot. Damned hot.
