• 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
  • 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, an era when rising sea levels flooded the caves.
  • Some of the oldest human remains in North America have been discovered in the sinkhole caves known as “cenotes” on the country’s Caribbean coast, and experts say some of those caves are threatened by the Mexican government’s Maya Train tourism project.
