👉 Ancistrothyrsus is a genus of extinct mammals from the Late Cretaceous period, which occurred around the same time as the Cambrian Period in the Earth's history. These animals are characterized by long, slender bodies and an elongated head with a short snout. They were primarily herbivorous and had large brains for their size. Ancistrothyrsus is believed to have been a major predator of its prey, which included other mammals and birds.
