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. It may have been a spinosaur, according to a 2019 paper, or a ceratosaur, according to the 2014 paper in which it was described. 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 describers considered it to be a basal ceratosaur, somewhat unusual given its young age. However, in an abstract given at the EAVP 2019 conference, Oliver Rauhut and colleagues suggested it is a member of the Spinosauridae rather than a ceratosaur, based on characters of the posterior caudal vertebrae and newly excavated material at the type locality, a 2019 dissertation by Adun Samathi concurred with that conclusion.
