Local dinosaurs included the ornithopod "Camptosaurus", the sauropods "Apatosaurus" and "Diplodocus", and the theropod "Allosaurus". Because of this, Riggs recombined "Brontosaurus excelsus" as "Apatosaurus excelsus". Other prominent dinosaurs contained in this clade include "Apatosaurus", "Supersaurus", and "Brontosaurus". Sauropods dominated the region, and included" Brachiosaurus", "Apatosaurus", "Diplodocus", "Camarasaurus", and "Barosaurus". Being related to both "Apatosaurus" and "Diplodocus", "Dinheirosaurus" probably possessed a squared snout. It shares some attributes with giant quadrupedal sauropods like "Apatosaurus". Compared with most sauropods, a relatively large amount of juvenile material is known from "Apatosaurus". Instead, Winston's former colleagues at Legacy Effects provided an animatronic "Apatosaurus" for the film. It was longer than "Apatosaurus", but its skeleton was less robust. The mount construction was overseen by Adam Hermann, who failed to find "Apatosaurus" skulls. Many species of "Apatosaurus" have been designated from scant material. The other subfamily of diplodocids is Apatosaurinae, which includes "Apatosaurus" and "Supersaurus". A pathology has been identified on the tail of "Apatosaurus", caused by a growth defect. He found that the neck of "Apatosaurus" was very flexible. In "Life's a Beach", Big Guy is seen with another "Apatosaurus", possibly his mate.
