Prehistoric human skeleton found in Mexican cave threatened by new tourist train

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.
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.
