Coelophysis bauri
读音: SEE-loh-FY-sis BOW-er-eye
Neotheropoda · Coelophysidae
One of the earliest known theropods, a slender, 3 m predator from the Late Triassic of New Mexico. Hundreds of skeletons from the Ghost Ranch quarry make it one of the best-known early dinosaurs.

概览
此内容目前仅提供英文版。
Coelophysis bauri lived at the end of the Triassic in what is now northern New Mexico, near the equator of the supercontinent Pangaea. Edward Drinker Cope named its first, fragmentary bones as Coelurus bauri in 1887 and moved them to the new genus Coelophysis in 1889.
In 1947 George Whitaker, in Edwin Colbert's American Museum crew, found a bonebed at Ghost Ranch packed with complete skeletons of all sizes. Because Cope's scrappy type bones could not be matched to them with certainty, the ICZN made a complete Ghost Ranch skeleton, AMNH 7224, the neotype in 1996.
It was a lightly built, two-legged hunter up to about 3 m long with a long, narrow head and grasping hands. Some Ghost Ranch skeletons were long said to hold eaten juveniles of their own kind, but Nesbitt and colleagues (2006) showed the "gut contents" were small crocodile-line reptiles, not young Coelophysis.
名称含义
"Hollow form", from Greek koilos ("hollow") and physis ("form"), for its hollow bones; bauri honours the palaeontologist Georg Baur (Cope 1887, 1889).

Rhaetian bin of the Ghost Ranch neotype quarry in PBDB. Cope's original sites are binned as Norian (227.3-205.7 Ma); the Petrified Forest Member is dated to about 211.9 Ma (secondary), and the age of the Ghost Ranch beds is debated.
