Concavenator

“Cuenca hunter”
TheropodcarnivoreEarly Cretaceous

A Spanish predator with a strange hump before the hips and possible quill knobs

Overview

Concavenator is a genus of carcharodontosaurid dinosaur that lived in Spain during the Early Cretaceous epoch, about 125 million years ago. The genus contains a single species, Concavenator corcovatus, named and described in 2010 from a nearly complete skeleton collected from the Las Hoyas fossil site of the La Huérguina Formation.

Why it matters

  • Described in 2010 from a near-complete skeleton in Las Hoyas, Cuenca.
  • Two tall vertebrae formed a pointed hump of unknown purpose.
  • Bumps on the forearm may be quill knobs, which would put feathers in a lineage far from birds.
