Apatosaurus Research Paper

The cervical vertebrae are less elongated and more heavily constructed than those of Diplodocus, and the bones of the leg are much stockier despite being longer, implying that Apatosaurus was a more robust animal. The tail was held above the ground during normal locomotion. It had a single claw on each forelimb and three on each hindlimb. The skull is similar to that of Diplodocus. It browsed foliage and likely held its head elevated. Air sacs permeated and lightened its vertebrae. In North America during the late Jurassic, Apatosaurus lived alongside
