Creature:Pyramidosaurus

Pyramidosaurus is a large carcharodontosaurid distinguished by its "pyramid" hump located on its lower back.

Description
Pyramidosaurus is a large biped with a scaly body, a long tail, a long narrow snout with a pair of "horns" projecting backwards over its head, and a triangular hump on its lower back. It's covered in blue-grey scales, with a darker back and lighter hands and feet. Its hump is the same medium tone of its tail and body, save for a darker base.

Like its closest real-life relative, Concavenator, Pyramidosaurus is depicted with simple quill-like feathers on its arms.
