Skull of the Altamura Man

The Altamura Man is a fossil of the genus Homo discovered in 1993 in a karst sinkhole in the Lamalunga Cave near the city of Altamura, Italy.  Remarkably well preserved but embedded in stalagmites and covered in a thick layer of calcite the find was left in situ in order to avoid damage

Altamura Man is one of the most complete Paleolithic skeletons ever to be discovered in Europe as "even the bones inside the nose are still there" and as of 2016 it represents the oldest sample of Neanderthal DNA to have been sequenced successfully
