Scientists from Mahasarakham University (Thailand) and the University of Bonn have examined the newly discovered caudal vertebrae of a spinosaurid dinosaur that could belong to Siamosaurus suteethorni. The comparison with finds around the world led to the realization that the Spanish Camarillosaurus is also a spinosaur and that often several species of these giant predators have inhabited the same area. The results have already been published online in the journal Historical Biology, and now an updated version has been published.
