👉 Ancodonta is a group of extinct sauropod dinosaurs that lived in the late Cretaceous period, approximately 69 million years ago. They were characterized by their large size and powerful jaws, which allowed them to climb trees and dig burrows. Their unique skull had five mandibles, which they used for chewing vegetation and other foods. Ancodonta likely evolved from a large sauropod that became extinct due to the loss of their diet or their inability to adapt to changing environments
