👉 Hypsimetopidae is a group of extinct, large-bodied mammals that lived during the Late Cretaceous period around 68 million years ago. These animals were characterized by their long necks and elongated bodies, which allowed them to reach high places with ease. They are known for being highly specialized in their diet, including a variety of plant-based foods, and had a streamlined body structure that made it easy to move through the sand.
