Dinosaur teeth from the Barremian of Uٌa, Province of Cuenca, Spain

The dinosaur fauna from the Barremian locality of Uٌa, east-central Spain, is described on the basis of isolated teeth. Apart from an unidentified sauropod and a probably new basal euornithopod, the fauna is noteworthy for its high diversity of theropods. The latter clade is represented by teeth of velociraptorine and dromaeosaurine dromaeosaurids, as well as Richardoestesia -like and Paronychodon -like teeth, making the theropod tooth fauna from Europe strikingly similar to the Late Cretaceous faunas from North America. However, the reported presence of more basal theropods from other Early Cretaceous localities in Europe indicate that this was a transitional fauna between the typical Late Jurassic and the typical Late Cretaceous theropod faunas of the Northern Hemisphere.
