Inaccuracies Edit

  • Saltopus is no longer considered a Dinosaur, but rather a dinosauriform
  • The reconstructions of certain dinosaurs (such as Oviraptor and Velocirapror) would have shown them with feathers
  • Teratosaurus is no longer considered a Dinosaur, but rather a rauisuchian
  • Spinosaurus is illustrated with a skull similar to Tyrannosaurus then to Baryonyx
  • Also, Baryonyx would be considered in the family Spinosauridae, it didn't have its own family Baryonychidae
  • Sauropods didn't raise their necks in the traditional swan-like fashion
  • Dinosaurs like Pachycephalosaurus didn't butt heads like goats
  • Anatosaurus isn't a valid genus
  • The scales of Stegosaurus and Triceratops are over-sized
  • The shields of ceratopsians were not used for defense
  • Palaelodus ambiguus is reconstructed with an incorrect head
  • The illustrations of Zygorhiza and Basilosaurus do not have vestigial fins
