An Aetosaur (reptilia:archosauria) from the Upper Triassic Chinle Group, Canyonlands National Park, Utah
A partial skeleton of the aetosaur Stagonolepis sp. is the first tetrapod body fossil recovered from Upper Triassic strata in Canyonlands National Park. The specimen consists of a partial tooth and numerous disarticulated vertebrae, ribs, and scutes found in the Blue Mesa Member of the Petrified Forest Formation (Chinle Group) near Upheaval Dome. Stagonolepis is an index taxon of the Adamanian ...
متن کاملFirst Report on Reptile Tracks from the Moenkopi Formation (lower-?middle Triassic) in Dinosaur National Monument, Utah
The Lower-Middle Triassic Moenkopi and Red Peak formations, which crop out throughout western North America, contain ubiquitous occurrences of tetrapod tracks attributed to reptiles (Peabody, 1948; Klein and Lucas, 2010; Lovelace and Lovelace, 2012). Although reptile skeletal remains from these formations are rare to non-existent, and largely restricted to the Holbrook Member in Arizona (e.g., ...
متن کاملAlgae (Dasycladales) from the Upper Triassic Nayband Formation (northeast Iran)
Dasycladales are relatively abundant in the bedded limestones of the Bidestan and Howz-e Khan members of the Late Triassic Nayband Formation in central Iran. In a locality south of the town of Naybandan (northwest of Dig-e Rostam), several Rhaetian dasycladacean algae were found in thin sections. The following taxa are described: Diplopora phanerospora Pia, Naybandoporella rhaetica nov. gen. no...
متن کاملUnusual tetrapod teeth from the Upper Triassic Chinle Formation, Arizona, USA1
Two teeth collected from the Upper Triasssic Chinle Formation of northeastern Arizona are described here and named Kraterokheirodon colberti gen. et sp. nov. These teeth are novel in having an occlusal ridge with six cusps and a posterior shelf lacking dentine. Evidence for thecodont implantation of the root suggests amniote affinities for these teeth. They do not match any teeth known for basa...
متن کاملKrzyzanowskisaurus, a New Name for a Probable Ornithischian Dinosaur from the Upper Triassic Chinle Group, Arizona and New Mexico, Usa
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 K. hunti appear more derived than R. c...
