Krzyzanowskisaurus hunti (Heckert, 2005) > Revueltosaurus hunti (Heckert, 2002)
Heckert, A. B. 2005. Krzyzanowskisaurus, a new name for a probable ornithischian dinosaur from the Upper Triassic Chinle Group, Arizona and New Mexico, USA; pp. 77-83 in A. B. Heckert and S. G. Lucas (eds.), Vertebrate Paleontology in Arizona. New Mexico Museum of Natural History and Science Bulletin 29. New Mexico Museum of Natural History and Science, Albuquerque.
Abstract
\\\"Recent discoveries have demonstrated that Revueltosaurus callenderi Hunt is not an ornithischian dinosaur, so it is probably not congeneric with the putative ornithischian Revueltosaurus hunti Heckert. Revueltosaurus Hunt, 1989 is the senior generic name, so I propose here the generic name Krzyzanowskisaurus for ?Revueltosaurus ?hunti.
Because the teeth of Krzyzanowskisaurus hunti appear more derived than Revueltosaurus callenderi, and are in fact more ?typically? ornithischian than those of Revueltosaurus callenderi, I tentatively suggest that it does in fact represent an ornithischian dinosaur.
Both Revueltosaurus callenderi and Krzyzanowskisaurus hunti have biostratigraphic significance. The former is an index taxon of the Revueltian land-vertebrate faunachron (lvf), and the latter is an index taxon of the Adamanian lvf. Indeed, the stratigraphic range of Revueltosaurus callenderi discriminates a discrete interval of Revueltian time (Barrancan) and that of Krzyzanowskisaurus hunti a subset of Adamanian time (St. Johnsian).\\\"
Based on teeth.
