Given its size, Chiappe says, the dino-headed bird would have most likely been a petite hunter, taking down the likes of beetles, grasshoppers and the occasional lizard rather than terrorizing the skies. Cratonavis might have used this impressive digit to hunt like today’s birds of prey, Li’s team says.įilling those shoes may have been too big of a job for Cratonavis, though. And that hefty big toe? It bucks the trend of shrinking metatarsals seen as birds continued to evolve. Rarely seen in Cretaceous birds, enlarged shoulder blades might have compensated for the bird’s otherwise underwhelming flight mechanics, the researchers say. But the new find “builds on our understanding of this primitive group of birds that are at the base of the tree of birds.”Ĭratonavis also had an unusually elongated scapula and hallux, or backward-facing toe.

This means that Cratonavis still hadn’t evolved the mobile upper jaw found in modern birds ( SN: 5/2/18). CT scans revealed that Cratonavis had a skull that was nearly identical (albeit smaller) as those of theropod dinosaurs like Tyrannosaurus rex, paleontologist Li Zhiheng of the Chinese Academy of Sciences in Beijing and colleagues report. The flattened specimen came from the Jiufotang Formation, an ancient body of rock in northeastern China that is a hotbed for preserved feathered dinosaurs and archaic birds.
