In 2014, divers were searching for Maya artifacts in a deep sinkhole in central Belize when they stumbled across the remains of a creature that long predated this ancient civilization. They found a humerus, a femur and part of a tooth belonging to the sloth. The area is a system of 25 lakes and cenotes, or natural sinkholes. The giant ground sloth, which could reach over 13 feet tall, was desperate for water. It found relief in a deep sinkhole, but it was never able to climb out.
