Castorocauda is a genus of small, semi-aquatic relative of mammals which lived in the Jurassic period, around 154 million years ago. It was found in lakebed sediments of the Daohugou Beds of Inner Mongolia. Castorocauda] was highly specialized, with adaptations like those of modern semi-aquatic mammals such as beavers, otters, and the platypus (convergent evolution). It also had traces of fur.[1]
Castorocauda] is one of the near-mammals in a group called the Docodonta.[1]
