    Category: Dinosaur

    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.
