Concavenator (Con-ca-ven-ah-tor), Hump backed hunter, lived in the Early Cretaceous of Spain. Concavenator was a basal carcharodontosaur with an unusual pointed hump on the spine above its pelvis. Skin is preserved from various parts of the skeleton and represents the earliest occurrence of scale and non-scale skin. It may be related to Becklespinax a potential carcharodontosaur from England that also has tall back bones.

Genera and Species

Classification: Theropoda, Tetanura, Carcharodontosauria

Species: C. corcovatus


Concavenator was had two raised backbones, each 1.3 feet (40 centimeters) taller than the dinosaurs' other vertebrae. A hump possibly supported a mound of fleshy tissue storing fat, as on a camel or display for attracting a mate or intimidating rivals. A series of bumps has on its forearm has been suggested to be similar in structure to quill knobs on birds.


LENGTH: 6 m (20 ft).

WEIGHT: 1.8 - 2.5 tons.


It preyed on sauropods and iguanodonts was probably a powerful runner; and likely ate small dinosaurs, crocodiles, and early mammals.
