Liliensternus liliensterni (Welles 1984) = "Halticosaurus" liliensternus (Huene 1934)
Fossilsite: Keuper Formation, Thueringen (Germany)
Age: 228 - 208,5 Mya (Norian, Upper Triassic)
Syntype: MB.R.2175
Description
Liliensternus liliensterni, originally described as Halticosaurus liliensternus, was a genus of big coelophysoid dinosaurs from late Triassic Germany. It reached a length of at least five metres and weighted approximately 200 lbs. Like other coelophysoids L.liliensterni was rather gracile, it had a relative long neck, the skull was quite small (~400mm). Because of its size, L.liliensterni was probably the apex predator in its ecosystem, but maybe competed against rauisuchids like Teratosaurus. Furthermore Liliensternus is often illustrated with crests similar to the crests of Dilophosaurus, but actual there is no evidence for that.
The fossils of L.liliensterni belong to two or more probably subadult specimen.

Systematics
Just like coelophysoidea in general the taxonomic position of Liliensternus was often discussed. Welles originally described it as a member of the today invalid Halticosauridae. In 1990 T. Rowe and J. Gauthier considered Liliensternus just like Dilophosaurus belong to Ceratosauria. Carrano et al. put it to Coelophysidae, but since 2004 L.liliensternus is seen as a coelophysoid and maybe somewhere at the basis of Dilophosauridae.
In 1993 Guny and Galton described a possibly second species from France called Liliensternus airelensis. Today it belongs to its own genus Lophostropheus.
