Megadicynodon

Megadicynodon is an extinct Dicynodont that lived in South Africa during the Late Triassic and was the most bizarre and largest of the Dicynodonts, being about 28 feet long and weighed about 7 tons, and it resembled a sauropod but with a beak. Megadicynodons probably lived in large herds much like sauropods and like them, they laid large clutch of eggs in similar-looking nests. They lived alongside the largest prosauropods and the earliest sauropods, and were probably preyed on by early large theropods. It may have became extinct from an extinction relating to the end of the Triassic period.
