Classification: Saurischia. Theropoda. Carcharodontosauridae.
Genus: Concavenator (“Cuenca [Province in Spain near where its remains were discovered] Hunter with a Hump”)
Species: C. corcovatus
Concavenator lived in an inland habitat with numerous lakes. It was a meat-eater, and while it was not as large as some of its later relatives, like Giganotosaurus, Carcharodontosaurus, and Acrocanthosaurus, it may still have been an apex predator in its environment.
Scientists aren’t sure about the purpose of its strange hump, but theorize that it may have been used for display.
A two-legged meat-eating dinosaur, Concavenator’s most notable feature were two distinctly tall vertebrae along its spine, which may have formed a hump or crest on the dinosaur's back.
Unique structures on the bones of its forearm are similar to quill knobs, which are mainly found in birds and indicate the presence of feathers. However, there is some debate among scientists about whether the structures on Concavenator are truly quill knobs.
