The famed Coelophysis quarry of Ghost Ranch, as it appears in 2019.. The type species of Coelophysis was originally named as a species of Coelurus. [11] Edward Drinker Cope first named Coelophysis in 1889 to name a new genus, outside of Coelurus and Tanystropheus, which C. bauri was previously classified in, for C. bauri, C. willistoni, and C. longicollis.

He described dozens of new taxa and authored major systematic reviews, including the discovery of more than a dozen complete skeletons of a primitive small Triassic dinosaur, Coelophysis at Ghost Ranch, New Mexico, in 1947 (one of the largest concentrations of dinosaur deposits ever recorded), [2] publication of their description, and a review ...
This unit is best exposed at Ghost Ranch, where it has produced the famous Whitaker Quarry, also known as the Coelophysis quarry due to a high concentration of fossils belonging to the theropod dinosaur Coelophysis bauri. The "siltstone member" may be equivalent to the Rock Point Member, and some authors refer to it as such. [22] [21] [19]
The only known fossil is a skull and neck fragments from deposits of the latest Triassic Chinle Formation at Ghost Ranch. Daemonosaurus was an unusual dinosaur with a short skull and large, fang-like teeth. It lived alongside early neotheropods such as Coelophysis, which
Its discovery alongside the relatives of Coelophysis and Herrerasaurus supports the hypothesis that the earliest dinosaurs arose in Gondwana during the early Late Triassic period in what is now South America, and radiated from there around the globe. [2] The specific name honours Ruth Hall, founder of the Ghost Ranch Museum of Paleontology. [3]
The Whitaker quarry of Ghost Ranch, New Mexico is believed to be located in the Rock Point Formation, although these beds have also controversially been assigned to the Owl Rock Formation.
