Chilesaurus diegosuarezi

Tyrannosaurus rex had a vegetarian cousin with a tiny head, long neck and stubby fingers.  Chilesaurus diegosuarezi had a bird-like beak with leaf-shaped teeth, evidence that it feasted on plants, but with hind leg features similar to theropod dinosaurs, the group into which it was slotted with notorious killers like Tyrannosaurus rex,Velociraptor and the horned Carnotaurus.
