Taveirosaurus is a tooth taxon of ornithischian dinosaur that lived in Portugal during the late Cretaceous. A tooth taxon is an animal that has only been described by teeth, and in the case of Taveirosaurus there have been many attempts to define what type of ornithiscian dinosaur that it was, almost always with differing results. Most palaeontologists prefer to class Taveirosaurus as a Nomen Dubium, as the teeth are just far too generic to confidently attribute any further remains to the genus.
