According to a cave-diving archaeologist on Mexico's Caribbean coast, an ancient human skeleton was unearthed in a tunnel system flooded 8,000 years ago.
Octavio del Rio and Peter Broger spotted the broken head and bones in a cave near where the Mexican government proposes to construct a tourist railway through the forest.
The skeleton couldn't have gotten there without current diving equipment, therefore it must be over 8,000 years old
"It is. "We don't know whether the corpse was put there or if this individual died there," Del Rio added.
The skeleton was found 26 feet underwater, nearly a third of a mile inside the cave system.
Del Rio, who has worked with the National Institute of Anthropology and History, reported the find.
