A fossil record exists of two adults and a 12.2-m-long (40 ft) juvenile that died together in the Late Jurassic epoch, around 150 million years ago (in northeast Wyoming, United States).

What did Camarasaurus eat?

DIET AND TEETH

Camarasaurus was an herbivore (it ate only plants). It must have eaten a tremendous amount of plant material each day to sustain itself. It swallowed leaves whole, without chewing them, and may have swallowed gastroliths (gizzard stones) to help digest tough plant fibers, like fern leaves and conifers .
