Riojavenatrix
''Riojavenatrix'' (meaning "La Rioja, Spain, La Rioja huntress") is a genus of spinosaurid theropod from the Early Cretaceous Enciso Group of La Rioja, Spain. The type species is ''Riojavenatrix lacustris''. ''Riojavenatrix'' represents one of five known spinosaurid taxa from the Iberian Peninsula, the others being ''Camarillasaurus'', ''Iberospinus'', ''Protathlitis'', and ''Vallibonavenatrix''. Discovery and naming Fossils of ''Riojavenatrix'' were discovered in 2005 at the Virgen del Villar-1 site in La Rioja, Spain. The holotype of ''Riojavenatrix'' is a fragmentary dorsal vertebra, pelvic girdle, and hindlimb elements that were initially assigned to ''Baryonyx''. Apparently, all the material belonged to the same individual because it was recovered in association with bones of consistent size and no duplicated elements. The Virgen del Villar-1 site is a part of the Enciso Group, dated as uppermost Barremian–lower Aptian. The age of this site is likely to be lower Apt ...

Camarillasaurus
''Camarillasaurus'' (meaning " Camarillas lizard") is a genus of theropod dinosaur from the Early Cretaceous period (Barremian) of Camarillas, Teruel Province, in what is now northeastern Spain. Described in 2014, it was originally identified as a ceratosaurian theropod, but later studies suggested affinities to the Spinosauridae. If it does represent a spinosaur, ''Camarillasaurus'' would be one of several spinosaurid taxa known from the Iberian peninsula, the others being '' Iberospinus'', '' Protathlitis'', ''Baryonyx'', '' Riojavenatrix'', and '' Vallibonavenatrix''. Discovery and naming Fossils of ''Camarillasaurus'' were discovered in the Camarillas Formation. The type species, ''Camarillasaurus cirugedae'', was described by palaeontologists Bárbara Sánchez-Hernández and Michael J. Benton. The generic name, "Camarillasaurus''", combines a reference to the geologic formation in which the holotype was found with the Greek "sauros", meaning "lizard". The specific name, ...
