Archaeornithoides was a 1 meter long therapod from the late cretaceous era. It was related to troodon which meant it was probably rather intelligent. It was rather like a bird and might of had feathers (sorry I couldn’t find a picture of a feathered archaeornithoides.) It hunted small mammals and lizards whilst avoiding being troden on by a clumsy t-rex, the complete opposite of Archaeornithoides.
