Minotaurasaurus - Challenge - 48

This hulking brute is Minotaurasaurus ramachandrani, a Late Cretaceous ankylosaur from... Well, we actually don't know for sure. The dinosaur is known only from its fossilized head, which was purchased by famed neuroscientist V. S. Ramachandran from a Japanese fossil dealer based in Arizona for $10,000. It likely originated in the Gobi Desert, but was collected and sold illegally and, as such, belongs properly to China - however, Dr. Ramachandran refuses to turn it over to the Chinese without any proof that it truly belongs to them. It was made available for study at a museum in California in 2007, and was thus officially described and named in 2009, but it is now once again held privately, and the outcome of the battle over ownership is still undecided.
