Liliensternus (formerly Halticosaurus , the "jumping lizard") was a medium-sized theropod dinosaur that lived in the Upper Triassic (late Norium ) in what is now Germany. The approximately 5.15 m long Coelophysoid is estimated to weigh about 127 kg.
The predatory dinosaur was named after Hugo Rühle von Lilienstern , who opened a palaeontological museum in the outbuildings of his castle in Bedheim on August 1, 1934 , in which the recently discovered dinosaur finds from Gleichberg near Römhild were shown. The museum was closed in 1969, the finds are now in the Museum für Naturkunde (Berlin) .
relationship
Although its membership of the Coelophysoidea is considered to be certain, it is still unclear to which family Liliensternus belongs. In the older literature the Halticosauridae is often used for this. However, this family is controversial. It is much more likely, however, that it belongs to a group of Coelophysoids, which branched off from the family tree of the Coelophysidae and possibly stood at the starting point for the later dilophosaurs .
In the past, in addition to the type species Liliensternus liliensterni , a dinosaur found in France was also included in the genus Liliensternus and described as Liliensternus airelensis . According to recent studies, this species was placed in its own genus ( Lophostropheus ).
