Field notes

About Dysalotosaurus

What it was like

Dysalotosaurus was a small, fast plant eater, a close relative of Dryosaurus. It had long legs, a beak and a stiff tail for balance.

Thousands of its bones have been found, from young animals and adults, which has let scientists study how it grew and even find signs of illness in its bones.

Its world

It lived in the Late Jurassic in what is now Tanzania, in eastern Africa. Its bones come from the Tendaguru beds, where it shared the land with the giant long-necked Giraffatitan and Dicraeosaurus, the stegosaur Kentrosaurus and the hunters Elaphrosaurus and Ceratosaurus.

How it was found

Virchow named Dysalotosaurus in 1919. Its bones were found in a bone bed that seems to hold a herd that died together.
