Protathlitis (meaning "champion") is a potentially dubious and chimeric genus of theropod dinosaur from the Early Cretaceous (Barremian) Arcillas de Morella Formation of Castellón, Spain. The type and only species is Protathlitis cinctorrensis, known from a partial skeleton. It was originally identified as a basal member of the Baryonychinae. If a spinosaurid identity of the material is correct, its discovery, as well as those of the spinosaurids Camarillasaurus, Iberospinus, Riojavenatrix, and the contemporary Vallibonavenatrix shows that the Iberian Peninsula held a diverse assemblage of these theropods during the Early Cretaceous.
== Discovery and naming == The holotype remains, the maxillary fragment 8ANA-109 and caudal vertebrae 3ANA83, 4ANA43, 4ANA69, 4ANA76, and 5ANA78, were recovered from the ANA site of the Arcillas de Morella Formation, which was discovered in 1998 and remained unexplored until 2002. A tooth, 4ANA-11, possibly from the left mandible or right maxilla, was also referred.
