Coelophysis bauri (Cope, 1887) theropod dinosaur from the Triassic of New Mexico, USA. This is a remarkable complete skeleton of the small early theropod Coelophysis. It comes from a nearly monospecific concentration of numerous complete to disarticulated skeletons in reddish-colored fluvial siltstones, often called a "Coelophysis graveyard". This occurrence has been interpreted as a carcass-jammed channel filling following mass mortality of dinosaurs by regional drought (see Schwartz & Gillette, 1994).

Geology and taphonomy of the Coelophysis Quarry, Upper Triassic Chinle Formation, Ghost Ranch, New Mexico. Journal of Paleontology 68: 1118-1130. Theropod were small to large, bipedal dinosaurs. Almost all known members of the group were carnivorous (predators and/or scavengers). They represent the ancestral group to the birds, and some theropods are known to have had feathers. Some of the most well known dinosaurs to the general public are theropods, such as Tyrannosaurus, Allosaurus, and Spinosaurus. © James St. John · CC BY 2.0 · Wikimedia

Un nouveau dinosaure carnivore du Trias identifié à Ghost Ranch
États-Unis Trias supérieur Trias fossile spécimen +5
Des chercheurs de Virginia Tech (Virginie, États-Unis) ont identifié une nouvelle espèce de dinosaure du Trias supérieur.  Le dinosaure a été nommé Ptychotherates bucculentus.  Ce nouveau taxon de dinosaure carnivore a été érigé sur la base de l'examen détaillé d'un fossile de crâne incomplet, bien conservé mais mélangé (numéro de spécimen CM 31368).  Le crâne provient de la Coelophysis de renommée mondiale
