Dicraeosaurus

Dicraeosaurus, meaning “double-headed lizard, or two-forked lizard”, is a genus of diplodocid dinosaur from the Late Jurassic Period. It was named for the spines on the back of its neck. It was discovered in rock bed on Tendaguru Hill in Tanzania. It was first described by paleontologist Werner Janensch in 1914.

This dinosaur was about 41 feet in length (smaller than other diplodocids). It had a large head with a short and wide neck, and a stiffened tail, unlike other diplodocids. Dicraeosaurus was a herbivore and was found with much larger herbivores of the time. It was able to co-exist without competition, as it most likely fed from a lower vegetation level than the larger specimens.
