Odontognathae

Odontognathae is a disused name for a paraphyletic group of toothed prehistoric birds. The group was originally proposed by Alexander Wetmore, who attempted to link fossil birds with the presence of teeth, specifically of the orders Hesperornithiformes and Ichthyornithiformes. As such they would be regarded as transitional fossils between the reptile-like "Archaeornithes" like Archaeopteryx and modern birds. They were described by Romer as birds with essentially modern anatomy, but retaining teeth.
