| 説明 | Diplodocus sp. juvenile sauropod dinosaur skull (29.2 cm long) from the Jurassic of Utah, USA (public display, CM 11255, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA).Sauropod dinosaurs were the largest terrestrial animals ever. They all have the same basic body plan: large body with four walking legs, very long neck & tail, and a small head relative to body size. Sauropods were herbivores, and are often perceived as holding their heads & necks up high to reach vegetation normally out of reach to other organisms. Modern reconstructions of many sauropod species depict them with heads and necks held close to the horizontal, or at low angles above the horizontal.This remarkable, complete, juvenlle Diplodocus skull was described in Whitlock et al. (2010). This specimen cannot be identified with certainty to the species level, as it was not associated with post-cranial skeletal elements.Classification: Animalia, Chordata, Vertebrata, Dinosauria, Sauropodomorpha, DiplodocidaeStratigraphy: Brushy Basin Member, Morrison Formation, Upper Jurassic, 151 MaLocality: Carnegie Quarry, Dinosaur National Monument, northeastern Utah, USA-------------Reference cited:Whitlock, J.A., J.A.
