Concavenator was a genus of theropod dinosaur that lived approximately 130 million years ago during the early Cretaceous period. The type species is Concavenator corcovatus which means "hump backed predator from Cuenca".The fossil was discovered in Spain by paleontologists José Luis Sanz, Francisco Ortega and Fernando Escaso.
Two extremely tall vertebrae in front of the hips formed a tall but narrow and pointed crest (possibly supporting a hump) on the dinosaur's back. The function of such crests is currently unknown. Paleontologist Roger Benson from Cambridge University speculated that one possibility is that "it is analogous to head-crests used in visual displays", but the Spanish scientists who discovered it noted it could also be a thermal regulator.
The forelimb (ulna) of Concavenator preserved evidence of what may be quill knobs or homologous structures, an anatomical feature so far known only in animals with large, quilled feathers on the forelimb. No impressions of any kind of integument were found near the arm, although extensive scale impressions were preserved on other portions of the body, including broad, rectangular scales on the underside of the tail and bird-like scutes on the feet. Feathers or related structures would then likely have been present...
