Amelia Island is practically in my back yard, about 40 miles from my location, so this story strikes a higher interest level for me. On Amelia island multiple burial mounds were found containing skeletons, and artifacts. Out of the hundreds of skeletons only perfect teeth were found.
A skull was found on the island that i hope to replicate with some information. An extremely large skull with perfect teeth, and perfectly preserved was found on the island a massive skull with two rows of teeth, and one with three rows. The third set being the start of a nucleus of a tooth. The skull was dry, not filled with soil in the cavities, perfect and complete.
Within a short time span of a couple of hours the skull crumbled to dust upon exposure to air.
