👉 Neoanthrenus is a type of extinct mammal that lived during the Late Cretaceous period, around 65 million years ago. It was characterized by its large size and elongated body shape, which allowed it to adapt to the harsh conditions of the desert environment in which it lived. Neoanthrenus had a long neck and could reach heights of up to 3 meters, making it an early example of a powerful land animal.
