Liliensternus ‭(‬Rühle von Lilienstern’s one‭)

Liliensternus is a genus of theropod dinosaur that lived in the Late Triassic period, around 210 million years ago. Its name is derived from the German paleontologist Hugo Rühle von Lilienstern, who discovered the first fossil remains in Germany in 1934. The type species is Liliensternus liliensterni.

Liliensternus was a medium-sized theropod, measuring about 4-5 meters (13-16 feet) in length and weighing around 200-300 kilograms (440-660 pounds). It was bipedal and carnivorous, with sharp teeth and claws for hunting and feeding on small to medium-sized prey.

Liliensternus is classified as a basal or early member of the theropod group, which includes more well-known dinosaurs like Allosaurus and Tyrannosaurus. As such, it provides valuable information on the evolution and diversification of these predatory dinosaurs during the Triassic period.
