The fossil of the minotaur Ankylosaurus is a complete skull, which was found in the Gobi desert of Mongolia. Minotaur Ankylosaurus' skull is similar in shape to a bull's head with bone armor. The skull is quite primitive and has the typical characteristics of Ankylosauridae. The minotaur Ankylosaurus was named by Clifford Myers and Clark Myers in 2009.

C.A. Miles and C.J. Miles published "The Neocretaceous Ankylosaurus-The Skull of Minotaurasaurus ramachandrani" in Contemporary Science. The type specimen inb 2 1004, including the skull and mandible, was preserved in California, USA, and was found in Gobi in Asia, but it is not clear whether it is Mongolian or China.

A new genus and species of Ankylosaurus was discovered in Upper Cretaceous in Gobi. It shows many characteristics of Ankylosaurus in the late Cretaceous. In the new specimen, the intact skull, two mandibles, and incisors were preserved in their original forms. There is almost no backlog and damage to this skull. There is an equilateral triangle on the back of its skull; A huge, tall, decorated nasal bone plate with huge nostrils, much like a bull. This skull is more primitive than other Ankylosaurus found in Gobi.
