Camarasaurus supremus

Camarasaurus supremus

Also known as Chambered Lizard

Camarasaurus supremus dominated Late Jurassic floodplains as an enormous high-browsing herbivore equipped with robust, spoon-shaped teeth designed to shear coarse conifer branches and cycad fronds. Its vertebrae featured prominent hollow chambers that dramatically reduced skeletal mass without sacrificing mechanical strength. Herds traveled across broad seasonal river basins, relying on immense bulk and powerful columnar limbs to deter contemporaneous predators.
