Clepsydrops sp.

Clepsydrops was a primitive amniote that was related to Archaeothyris and the synapsids - the ancestors of mammals. It lived one or two million years earlier than Archaeothyris. But it was not as old as Protoclepsydrops, a possible primitive synapsid and ancestor. Like many other terrestrial early amniotes, it had the diet of insects and smaller animals, and it laid eggs on land rather than on water, as most of its ancestors did. Its jaws were slightly more advanced than Paleothyris, and Hylonomus.
