Animal and human bones over 12,000 years old have been found buried in an ancient graveyard at the bottom of an underwater cave in Mexico.
The discoveries include ancient sloths, tapirs, sabertooth cats, cougars, elephant-like gomphotheres, bears, dog-like animals as well as a couple humans
According to RT: Experts say the “underworld of exquisitely preserved fossils” includes human remains that are over 12,000 years old and the skull of a large, short-faced bear. The Hoyo Negro pit is a natural time capsule from the Late Pleistocene era. Before it was underwater, animals would fall 60 meters into the cave to their deaths.
