Info

Lophostropheus airelensis (Ezcurra and Cuny, 2007) > Liliensternus airelensis (Cuny & Galton, 1993)

In the early 1990s a theropod dinosaur found close to the Triassic-Jurassic boundary of France was assigned to a second species of the genus Liliensternus: L. airelensis (Moon Airel Formation). This contribution reveals that common features that purportedly unite “L.” airelensis with L. liliensterni are more widely distributed among coelophysoids and basal dinosaurs than it was thought. A cladistic analysis reveals that “L.” airelensis is more closely related to the Coelophysidae than to L. liliensterni. A feature that supports this systematic arrangement includes a supraacetabular crest forming a well-developed ridge continuous with the lateral margin of the brevis fossa, with non-distinct notch between both structures. The new genus Lophostropheus, gen. nov., is therefore erected to include the species L. airelensis. Thus, the new combination Lophostropheus airelensis is proposed. (Ezcurra and Cuny , 2007)

Description

Lophostropheus airelensis is a new genus name for \\\'Liliensternus\\\' airelensis from Normandy, France. A closer reinspection of the French \\\'L.\\\' airelensis has shown that it is not as closely related to the German Liliensternus, L. liliensterni, but in fact closer to Coelophysis and Syntarsus. Thus, the authors attribute a noval genus name Lophostropheus to \\\'L.\\\' airelensis.
