Okay, what is it? With its strange anatomical features, enormous eye orbits and somewhat minuscule dentition, it can't be human. These are the type of questions and interest one might expect from students when they are confronted with this unusual mock-alien skull. Brilliantly sculpted, this hypothesized cranium is useful when coupled with real skulls, aiding in understanding the underlying support for muscles and organs. So what is it? A great teaching aid.
