Omeisaurus maoianus

† Omeisaurus maoianus is a Late Jurassic sauropod from China. This long-necked herbivore of the Dashanpu Formation had more than 17 cervical vertebrae and reached lengths of ~18 m in lush Jurassic floodplain environments.

Diet & Feeding

Herbivore

Omeisaurus maoianus 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

Omeisaurus maoianus 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.
