Dicraeosaurus (Gr. dikraios, dikraios “bifurcated, double-headed” + Gr. sauros, “lizard”) is a Genus of diplodocoid sauropod dinosaurs that lived in the area of Tanzania in the latter part of the Jurassic period. The genus’ name was derived from the neural spines found on the back of the neck. First fossils were first described by the paleontologist Werner Janensch in 1914.

In contrast to most diplodocoids Dicraeosaurus had a rather large head and a long and broad neck. The neck had 12 vertebrae that were unusually small that could be a sign of an extremely low-level searcher of vegetation that was less than 3 meters (9.8 feet) from the ground. Dicraeosaurus was also devoid of it’s “whiplash” tail tip typical of diplodocoids. It was also smaller than other diplodocoids, measuring only 12 meters (39 feet) of length but it was still among the more well-known members of the family of Dicraeosauridae. The genus is famous for its rather large neural spines protruding out of the vertebrae that the genus is named after. They weren’t straight like in other relatives, but instead they formed the shape of a rough “Y” shape. The spines could have served as muscles with attachment points.
