Yunnanosaurus

† Yunnanosaurus is an Early Jurassic sauropodomorph from the Lufeng Formation of Yunnan Province, China, transitional between true prosauropods and sauropods. Its socketed teeth resemble those of basal sauropods, placing it near the origin of the sauropod lineage.

Time Period

Jurassic Early Mesozoic Era

Yunnanosaurus lived during the Jurassic Early period of the Mesozoic Era, approximately 201,4 to 174,7 million years ago.

After the Triassic-Jurassic extinction, dinosaurs rapidly diversified and became the dominant land vertebrates. Early sauropods and theropods began to evolve larger body sizes.
