Some Things to Do, and a Progress Update
In the meanwhile, we’re still trying to pull together a few last measurements for the analysis. We have gotten a few new data submissions, and these all require verification entries. There are also a few papers that can be combed for measurements. So, there is still an opportunity to make a contribution.
Notes on Phylogeny
Updates on non-dinosaurian archosaurs from Nesbitt 2011 analysis:
Scleromochlus – position retained from old tree (not included in Nesbitt phylogeny)
Gracilisuchus and aetosaurs resolved arbitrarily at “base” of Pseudosuchia (position of clades not resolved in Nesbitt’s analysis)
Hallopus placed as per previous version of cladogram
Polacanthus is arbitrarily placed as sister to Gastonia+Tatankacephalus (i.e., made as an ankylosaurid rather than a nodosaurid; will need discrete reference to justify this decision).
Position of Tatankacephalus follows Parsons & Parsons 2009
