Camarasaurus grandis

† Camarasaurus grandis was a large species of the sauropod genus Camarasaurus from the Late Jurassic Morrison Formation of North America. Among the larger Camarasaurus species, it was a quadrupedal herbivore with a deep skull, robust spatulate teeth, and excavated vertebrae. Well-represented by multiple specimens including near-complete skulls, C. grandis contributed substantially to early understanding of sauropod anatomy. It browsed on high and low vegetation in the semi-arid Late Jurassic flood-plains of western North America.

Diet & Feeding

Herbivore

Camarasaurus grandis was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Camarasaurus grandis lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
