Ancient species of giant sloth discovered in Mexico
The bottom of a deep sinkhole, in the middle of what today are the idyllic Caribbean beaches of Mexico, was the tomb of a giant sloth that lived some 10,000 years before the common era, whose discovery was announced Wednesday by Mexican scientists.
Remains of the Pleistocene era were found in 2010, but they were so deep into the well filled with water that researchers were only able to gradually unite what the INAH National Institute of Anthropology and History were to announce the finding. 
So far, scientists have dragged the skull, jaw and a mixed bag of vertebrae, claws and other bones, but the rest of the skeleton remains about 50 meters underwater.
