Adeopapposaurus mognai

†Adeopapposaurus mognai was a prosauropod sauropodomorph from the Early Jurassic (~193 Ma) of San Juan Province, Argentina. About 3-4m long, it was a bipedal herbivore with a small head and long neck. Named by Martínez in 2009 from multiple specimens, it contributes to the diverse prosauropod fauna of Early Jurassic South America.

Time Period

Jurassic Early Mesozoic Era

Adeopapposaurus mognai 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.
