New theropod paper: *Sarcosaurus* and *Zupaysaurus* are coelophysoids.
Carrano, M.T. & S.D. Sampson, 2004. A review of coelophysoids (Dinosauria:
Theropoda) from the Early Jurassic of Europe, with comments on the late
history of the Coelophysoidea. N. Jb. Geol. Palaont. Mh. 2004 (9): 537-558.
Abstract: We review the available materials of Early Jurassic European
theropods and confirm several as belonging to the clade Coelophysoidea.
These include the holotypic partial skeleton of *Liliensternus arielensis*
(France), fragmentary remains referred to as *Sarcosaurus woodi* and
*Sarcosaurus andrewsi* (England), and a distal tibia (Scotland). Although
incomplete, these specimens indicate that a wide size range of coelophysoids
existed in Europe throughout the Early Jurassic, much as in North America.
The record of coelophysoids from other continents is also reviewed, with
particular attention to the later history of the clade. Coelophysoids
apparently remained common worldwide into the Early Jurassic. They appear
to have gone extinct by the end of the Early Jurassic, although the poor
Middle Jurassic record may yet reveal late survivors of the group.
