A new article is now available online: Michelle R. Stocker; Sterling J. Nesbitt; Katharine E. Criswell; William G. Parker; Lawrence M. Witmer; Timothy B. Rowe; Ryan Ridgely; Matthew A. Brown (2016). "A Dome-Headed Stem Archosaur Exemplifies Convergence among Dinosaurs and Their Distant Relatives". Current Biology. in press. doi:10.1016/j.cub.2016.07.066. Triopticus is just another one of the many additions of the list of Triassic reptiles that are superficially similar to dinosaurs but fall outside Dinosauromorpha. This discovery brings to mind the putative Triassic pachycephalosaur from India (mentioned in Naish and Martill 2001 and Butler and Sullivan 2009), and it's almost certain that the "Triassic pachycephalosaur" could be a relative of Triopticus, since the putative pachycephalosaur classification of the Indian form, like the ornithomimosaur classification of Shuvosaurus and avialan classification of Protoavis, was greeted with skepticism by Chatterjee's critics.

A pair of fish on one small slab. I believe the ray-finned fish is either Synorichthys sp. or Turseodus sp. You can see the body of a Diplurus newarki just below the other fish scales. Late Triassic, (Rhaetian) Lockatong Formation, Newark Supergroup, North Bergen, New Jersey.© © 2015 Tim Jones

An article you might find interesting…... http://www.alaskapublic.org/2013/09/18/thalattosaur-fossil-discovered-near-kake-may-be-new-species/ I first heard of Thalattosaurus when I read a book about prehistoric reptiles from California, and I didn't know that Mesozoic marine reptiles inhabited the waters off the Pacific Coast of the US until I read about where Shastasaurus has been found. The discovery of a thalattosaur from Alaska shows that North American thalattosaurs roamed the Pacific Coast as far north as Alaska.
