Carcharodontosaurids are generally large allosauroid theropods (With the exception of Carcharodontosaurids like Concavenator).

Biology

Mostly "huge", Carcharodontosaurids had several distinguished traits.

Most Carcharodontosaurids possessed slender teeth, suitable for slicing and gripping flesh. An example of a fairly unique Carcharodontosaurid would be Concavenator, which possessed a hump upon its back. Indentations in the arm may have suggested that Concavenator and (possibly) other Carcharodontosaurids possessed quill like feathers on the arm.
