A recent paper
by MacDougall et al. (2013) reported on the post-crania of the Early Triassic reptile, Sauropareion (Fig. 1). The description was excellent.
A phylogenetic analysis was performed by them (Fig. 2) to nest Sauropareion. While their test included several taxa I have not tested (everyone needs a new project for the new year), the large reptile tree found a much different nesting (color notes in Fig 2), at the base of the owenettids, and, by extension, at the base of the Lepidosauriformes, close to Paliguana.
We need to take a large look at procolphonids
Unfortunately Procolophonidae has become a wastebasket taxon for any small reptile with short toes and a large orbit. A large gamut phylogenetic analysis is needed to correctly nest the many taxa that have been attributed to it — and to correctly nest the Procolophonidae itself.
Phonodus nests with bolosaurs in the large reptile tree, not far from procolophonids and diadectids.
Assumptions and traditions
need to be tested in a larger gamut analysis. If I have any influence over the study of paleontology, this is what I want, a large gamut analysis by someone else to test the large reptile tree.
