Yandusaurus

† Yandusaurus is a Middle Jurassic ornithopod from the Dashanpu Formation of Zigong, Sichuan, China. This small, lightly built herbivore was one of the most common small dinosaurs at the Jurassic Dashanpu site, coexisting with large sauropods and carnivores.

Diet & Feeding

Herbivore

Yandusaurus 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

Yandusaurus 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.
