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.

History
Sacrum and centrum

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.[1] 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,[2] a 2019 dissertation by Adun Samathi concurred with that conclusion.[3]
