Camarasaurus
The arched skull of Camarasaurus was remarkably square and the blunt snout had many fenestrae (openings). It was sturdy and is often found in good condition by paleontologists. The 19 centimeter long (7.5 in) teeth were shaped like chisels (spatulate) and arranged evenly along the jaw. The strength of the teeth indicates that Camarasaurus probably ate coarser plant material than the slender-toothed diplodocids.
