Eshanosaurus
Eshanosaurus was an early relative of the strange, long-clawed therizinosaurs. It lived about 200 million years ago in what is now China. Only a piece of its lower jaw has been found, so scientists are still debating what it really was.1

Eshanosaurus is known only from a partial left lower jaw and some teeth.1
If Eshanosaurus is a therizinosaur, it would be the oldest known coelurosaur, living about 60 million years before other early therizinosaurs like Falcarius.12
The name Eshanosaurus means 'Eshan lizard,' after the region in China where it was found.1
Its species name, deguchiianus, honors Hikaru Deguchi, who encouraged the scientist Xu Xing to study dinosaurs.1
Eshanosaurus lived during the Early Jurassic Period, between about 201 and 199 million years ago.4
Some scientists think Eshanosaurus might actually be a prosauropod (a long-necked plant-eater) rather than a therizinosaur.1
