The Plesiogulo is a Early Gulo Skull and the size is about 19*17*9 cm. It's hard to find such a complete skull. The teeth and bones are very beautiful. Ancient Gulo are still different from modern Gulo. There are some bones next to it. These are fossils formed by river alluvial deposits. Plesiogulo is an extinct genus of giant mustelids that lived during the Miocene and Pliocene epochs. Commonly known as the "near-wolverine," it was one of the largest mustelids in history. Larger species weighed between 35 to 50 kg, roughly twice the size of modern wolverines.
