The 24 foot Ouranosaurus was an interesting ornithopod from Early Cretaceous Africa, where it coexisted with the fish-eating theropod Suchomimus. Its name means “brave lizard”, and some distinguishing traits of Ouranosaurus were its thumb spikes and the elongated neural spines of its back. It was once assumed that these spines supported a skin sail, but their robust form makes it seem more likely that they were for muscle attachment or supported a hump similar to a camel’s.
