Omeisaurus jiaoi

† Omeisaurus jiaoi is a Middle Jurassic mamenchisaurid-grade sauropod from China. This large quadrupedal herbivore with an extremely elongated neck browsed high vegetation in Jurassic East Asian forest environments.

Diet & Feeding

Herbivore

Omeisaurus jiaoi 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 Middle Mesozoic Era

Omeisaurus jiaoi lived during the Jurassic Middle period of the Mesozoic Era, approximately 174.7 to 161.5 million years ago.

Dinosaur diversity continued to increase, with the evolution of large sauropods and diverse theropods. Stegosaurs first appeared, and the supercontinent Pangaea was breaking apart.
