In 1993, scientists found an extraordinarily intact skeleton of an ancient human amidst the stalactites and stalagmites of the limestone cave of Lamalunga, near Altamura in southern Italy — a discovery they said had the potential to reveal new clues about Neanderthals.
"The Altamura man represents the most complete skeleton of a single nonmodern human ever found," study co-author Fabio Di Vincenzo, a paleoanthropologist at Sapienza University of Rome, told Live Science. "Almost all the bony elements are preserved and undamaged."
The Altamura skeleton bears a number of Neanderthal traits, particularly in the face and the back of the skull. However, it also possesses features that usually aren't seen in Neanderthals — for instance, its brow ridges were even more massive than those of Neanderthals. These differences made it difficult to tell which human lineage the Altamura man might have belonged to. Moreover, the Altamura skeleton remains partially embedded in rock, making it difficult to analyze.
