This set of three massive dinosaur fossil bone rib sections from a Camarasaurus, is a fantastic educational or display set as it demonstrates the sheer massiveness of these Jurassic giants. Each rib section has been cleaned and repaired with minor crack filling, in our lab. Each dinosaur rib bone is stable and safe to handle making this a great teaching specimen set.
Camarasaurus was a genus of quadrupedal, herbivorous dinosaurs. It was the most common of the giant sauropods to be found in North America. Its fossil remains have been found in the Morrison Formation of Colorado and Utah, dating to the Late Jurassic epoch (Kimmeridgian to Tithonian stages), between 155 and 145 million years ago.
Camarasaurus possessed a distinctive cranial profile of a blunt snout and an arched skull that was remarkably square. 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.
The maximum size of the most common species, C. lentus, was about 15 meters (49 ft) in length. The largest species, C. supremus, reached a maximum length of 23 meters (75 ft) and maximum estimated weight of 47 tonnes (51.8 tons).
