"Here's a strange skull in a museum in Brazil. It was mummified when it was presumably brought from Egypt." Or, a "grey alien skull". No idea what this was modeled with (human + ??), but it's not a real primate skull... Indicating, obviously, that it's an ALIEN!!! Or model from http://www.boneclones.com/CC-05.htm
Several human skulls with horns protruding from them were discovered in a burial mound at Sayre, Bradford County, Pennsylvania, in the 1880's. With the exception of the bony projections located about two inches above the eyebrows, the men whom these skeletons belonged to were anatomically normal, although at seven feet tall they were considered to be giants. Burial was believed to have been in the neighborhood of 1200 AD.
