Description
Eoraptor was a small, lightly built dinosaur with long hind legs and a flexible tail. Its teeth vary in shape and may indicate a mixed diet of small animals and plants. It lived in a seasonal landscape of rivers and woodland. The early dinosaur family tree is difficult to resolve, and Eoraptor's precise position has been revised over time.
Habitat
River-valley and woodland environments in the south-west of Pangaea.
