Sellosaurus

Sellosaurus is a genus of prosauropod dinosaur that lived in Triassic Europe, 225 mya. It was about 23 feet (7 meters) long, 7 feet (2.1 meters) tall and weighed 2,000 pounds (909 kilograms). Like other prosauropods, it had a thumb claw it may have used to defend itself, and reach for food. It physically resembled Plateosaurus, although initially the relationship between these animals was uncertain. A point of contrast between the two genera pertains to the variability in the teeth at the front and back of the jaw. Of the two, Sellosaurus had the highest level of variation.

Discovery
Sellosaurus is one of the more well-known prosauropods. Over twenty skeletons have been so far discovered. These fossils were found in strata dated to the middle Late Triassic and located in Nordwurttemberg, Germany. The remains comprise what is believed to be at least three separate species. The dinosaur Efraasia, a prosauropod from the same location, was long thought to be the same as Sellosaurus, but this has been recently disproved.
