Yuanmousaurus jiangyiensis

† Yuanmousaurus jiangyiensis is a Middle Jurassic mamenchisaurid sauropod from the Yuanmou Formation of Yunnan Province, China. This giant-necked sauropod inhabited the ancient lake basins of Yunnan alongside early stegosaurs and carnivorous theropods.

Diet & Feeding

Herbivore

Yuanmousaurus jiangyiensis 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

Yuanmousaurus jiangyiensis 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.
