Field notes

About Dicraeosaurus

What it was like

Dicraeosaurus was a smallish sauropod with a short neck for its kind, and tall, forked spines rising from its neck and back bones. Those spines may have supported a ridge along its neck.

It probably fed on low plants and was a relative of Amargasaurus, which had even longer spines.

Its world

It lived in the Late Jurassic in what is now Tanzania, in eastern Africa. Its bones come from the rich Tendaguru beds, where it shared the land with the much larger long-necked Giraffatitan, the spiky stegosaur Kentrosaurus and the slender hunter Elaphrosaurus.

How it was found

Janensch named Dicraeosaurus in 1914. With 19 finds, it is one of the best known dinosaurs from Africa.
