👉 Centrorhynchidae are a family of extinct marine reptiles that lived during the late Paleocene and early Eocene, approximately 63 million years ago. They were characterized by their large, elongated jaws with serrations on the edges, which allowed them to grasp and hold onto prey. Centrorhynchids were also known for their long, slender necks and distinctive beak-shaped teeth that served as a key tool for hunting and other foraging activities.
