👉 Pteranodontidae is a family of extinct sauropodomorph dinosaurs that lived during the Cretaceous period, around 68 to 72 million years ago. They were a group of dinosaurs with long necks and a large head, which allowed them to climb trees for protection from predators. The pterosaurs are often referred to as "clawed dinosaurs" because they had sharp claws on their forelimbs that could be used for climbing and reaching food sources.
