Hunterian Museum at The Royal College of Surgeons of England in London has this fascinating medical specimen on display that shows what a child’s skull looks like when its adult teeth are waiting in the wings. It won’t be long before those deciduous (baby) teeth are booted out.
Jaws. In 1888, seven skeletons were found in a burial mound near Clearwater Minn. They were anatomically correct, except that the skulls featured double rows of teeth in the upper and lower jaws and had been buried in a sitting position, facing the lake. The foreheads were unusually low and sloping, with prominent brows.
No it's not the Nephilim or an alien. Artificial cranial deformation, head flattening, or head binding is any practice of intentionally deforming the skull of a human being. It is done by distorting the normal growth of a child's skull by applying force. Flat shapes, elongated ones (produced by binding between two pieces of wood), rounded ones (binding in cloth) and conical ones are among those chosen. It is typically carried out on an infant, as the skull is most pliable at this time.
