Taveirosaurus

Taveirosaurus (meaning "Taveiro lizard") is a genus of possibly eutriconodontan mammal from the Late Cretaceous Argilas de Aveiro Formation of Portugal, and also Laño, Spain. The genus is based solely on teeth, and the type species is T. costai.

== Discovery and naming == In 1968, Miguel Telles Antunes and Giuseppe Manuppella uncovered fossils at the Cerâmica do Mondego quarry near Taveiro, a village in Portugal, southwest of Coimbra. Among them were a number of low triangular teeth of a herbivorous dinosaur. In 1991 these were named and described by Telles Antunes and Denise Sigogneau-Russell as the type species, Taveirosaurus costai. The generic name refers to Taveiro. The specific name honours the Portuguese geologist João Carrington da Costa.
