👉 Apalos are a group of extinct marine mammals that lived during the Paleocene and Eocene periods. They were found in various parts of the world, including Africa, Asia, Australia, and North America. Apalos had large brains, long necks, and strong jaws, which allowed them to hunt for prey and defend themselves against predators. Some species of apalos are thought to have been closely related to modern whales and dolphins, while others lived in solitary groups.
