Ancient skeleton found in underwater cave in Mexico threatened by Maya Train project

A prehistoric human skeleton has been found in a cave system that was flooded at the end of the last ice age 8,000 years ago, according to a cave-diving archaeologist on Mexico's Caribbean coast.

Archaeologist Octavio del Rio said he and fellow diver Peter Broger saw the shattered skull and skeleton partly covered by sediment in a cave near where the Mexican government plans to build a high-speed tourist train through the jungle.

Given the distance from the cave entrance, the skeleton couldn't have gotten there without modern diving equipment, so it must be over 8,000 years old, Del Rio said, referring to the era when rising sea levels flooded the caves.
