Here are a few new Triassic papers officially out today, all open access. A couple were out as early access, but the new phytosaur phylogeny paper is new today in PeerJ. This represents the bulk of the senior authors dissertation, is an exhaustive analysis of the phytosaurs, and a great exercise in database exploration for a group that has been particularly troublesome to deal with taxonomically and phylogenetically.
Phytosaurs are an incredible group of archosauriforms, common in Late Triassic rocks. Although problematic they serve as a great group for students to learn basic cranial and skeletal anatomy and we use them for this purpose at the Petrified Forest. Numerous and diverse they go extinct at the end of the Triassic and that is a mystery that colleagues such as Randall Irmis from the University of Utah are trying to solve. This research was featured last week on Science Friday.
