Sauropodomorpha

Sauropodomorpha was a suborder of dinosaurs that included the herbivorous prosauropods and the more widely known sauropods. These dinosaurs, which evolved from meat-eating ancestors, are characterized by their leaf-shaped teeth, small heads, and long necks that were at least as long as their bodies.12

Prosauropods, the more primitive members, were generally smaller, ranging from less than 2 meters to about 8 meters in length. They appeared in the Late Triassic and Early Jurassic periods and were found globally.1

Sauropods, the descendants of prosauropods, became much larger, with some species reaching lengths of up to 30 meters and weighing up to 80 metric tons. These massive, four-legged herbivores, known for their long necks and tails, dominated the dinosaur landscape from the Late Jurassic to the end of the Cretaceous Period.32
