👉 Gorteriinae is a family of extinct marine animals that lived during the late Cretaceous period, around 65 million years ago. They were part of a large group known as "Cretaceous Plesiosaurs," which included various species that are now classified in the order Plesiopeida. These plesiosaurians had a distinctive body shape with long necks and powerful jaws, which allowed them to reach high places on land.
