With eye sockets only 0.6" deep, there's no room for eye muscle attachments, much less for its eyes to roll around. With a flat maxillary hard palate,(not found in any mammal), its tongue was as thick as a piece of cardboard. Its neck was as big around as the average wrist and came out the center of the bottom of the skull. Aluminum was a bone component!!(from the AMS mass spectral analysis of SC bone). And it fits inside the head of a grey alien!
Okay, I quoted the owner of the skull.......but it does. That's the first thing that hits you when you look at it. Sheesh! Here's the dead alien body folks and still you don't believe!
