Remains: Fathead Skulls 1

Robert Connolly has photographed a similar, more complete skull. In most respects it appears to be that of a human, except that it has an extraordinarily large cranium and eye sockets. The eye sockets are about 15 percent larger than a modern human's. The age and date of the skull are unknown. Similar skulls appear in photos by Karen Scheidt of remains found in a Mexican cave. Could they all be genetic mutations, some unknown species of creature or something not of this world?
