Nuthetes destructor Owen
Early Cretaceous (Berriasian)
Chevres-Richemont Quarry
Chevres-de-Cognac, Charente, SW France

Extremely rare 11mm theropod.

Nuthetes is a theropod known only from teeth and jaw sections collected in western Europe so paleontologists haven’t been able to assign it to a particular family.  It has been considered an early dromaeosaur but it might be a relative of early tyrannosaurs. 

Few teeth reach the market so you better grab this one before a French collector sees it.
