Info
Genus - Typespecies
Based on 5+ teeth, the basioccipital, and cervicals 1 to 3, Mongolosaurus haplodon from the Early Cretaceous of Mongolia is difficult to classify. The basioccipital is relatively shorter than those of Camarasaurus and Brachiosaurus, and the heavy descending processes are considerably shorter than those of Camarasaurus and shorter dorsoventrally than those of Diplodocus. The teeth are unique among sauropods. They are slender and cylindrical and convex on both faces of the crown, which tapers to a slightly blunted point at the tip. Carinae develop on either edge and extend to the apex of the crown. In some of the teeth, the carina is slightly serrate.
