  • Fossils had been disarticulated however discovered shut collectively
  • Additionally discovered a doable neck vertebra, that was later discovered to be too small to be a part of the identical Camarillasaurus specimen, and even belong “to the identical taxon as Camarillasaurus”, in response to Samathi and others in 2021
  • Initially considered a ceratosaur, then considered a spinosaur as of 2021
  • When Camarillasaurus was considered a ceratosaur, it was vital as a result of it helped fill within the hole (ceratosaurs identified from the Center and Late Jurassic, after which the Late Cretaceous, and Camarillasaurus lived within the Early Cretaceous)
  • Oliver Rauhut and others recommended Camarillasaurus was a spinosaur in 2019 primarily based on its tail vertebrae and after evaluating it to new fossils discovered the place Camarillasaurus was discovered
  • In 2021, Adun Samathi and others tentatively agreed (discovered Camarillasaurus to be a megalosauroid and probably a spinosaur), and likewise discovered similarities between Camarillasaurus and spinosaur fossils present in Thailand
  • Want extra fossils to know for certain
  • For instance, discovered tail vertebrae in Thailand that appeared much like Baryonyx, primarily based on grooves and depressions within the bones
  • Samathi and others discovered the proof for Camarillasaurus being a ceratosaur to be “doubtful and restricted”, and that the unique paper describing Camarillasaurus didn’t cite options distinctive to ceratosaurs, and lots of the options described are seen in tetanuran theropods and a few had been misinterpreted or misidentified
  • One in every of 4 spinosaurs identified from the Iberian peninsula, in Spain and Portugal: Camarillasaurus, Baryonyx, Vallibonavenatrix, Iberospinus
  • Different dinosaurs that lived across the identical time and place included sauropods, dromaeosaurs, ornithischians
  • Different animals that lived across the identical time and place included turtles, snakes, fish, mammals, and crocodilians
