At the same time, Tarascosaurus is based on a very fragmentary specimen and I suspect its position is so unstable among Abelisauroidea that it's possible that every time a few modification in the phylogeny is added it alters Tarascosaurus position and thereforeAndrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-9930014334907414202012-03-14T06:06:13.932+01:002012-03-14T06:06:13.932+01:00It'd be a combination of plesiomorphies and ap...It'd be a combination of plesiomorphies and apomorphies (those characters placing it with Deltadromeus and Elaphrosaurus, or inside Noasauridae).Mickey Mortimerhttps://www.blogger.com/profile/08831823442911513851noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-42617727498378635372012-03-13T19:57:01.862+01:002012-03-13T19:57:01.862+01:00I suspect most of the reviewers of a paper suggest...I suspect most of the reviewers of a paper suggesting such a diagnosis for Tarascosaurus would consider it as a nomen nudum arguing that it's based on plesiomorphies.Andrea Cauhttps://www.blogger.com/profile/10855060597677361866noreply@blogger.comtag:blogger.com,1999:blog-2156944512466583246.post-3353696619580684972012-03-13T19:27:51.583+01:002012-03-13T19:27:51.583+01:00But if your analysis places it closest to Deltadro...But if your analysis places it closest to Deltadromeus/Bahariasaurus and Elaphrosaurus, and the femur differs pretty clearly from both (e.g. more distally placed and cylindrical anterior trochanter is different from Deltadromeus, femoral head not strongly tilted anteriorly is different from Elaphrosaurus), how can Tarascosaurus be a nomen dubium?
