Parapengornis

Parapengornis had a very broad and short tail bone (pygostyle) that was wider than it was long, which is unusual for early birds.2

Its tail bone looked like that of modern woodpeckers, so scientists think Parapengornis could climb up tree trunks and cling to bark.2

This bird had long, slender teeth that were constricted at the base and slightly curved backward, perfect for grabbing slippery prey.2

Parapengornis was one of the largest early Cretaceous enantiornithine birds, about the size of a modern crow.2

The fossil of Parapengornis was found with impressions of its wing and tail feathers, showing it had fully developed flight feathers.2

It lived alongside many other early birds and dinosaurs in the Jehol Biota of China, about 120 million years ago.2
