Somewhat related to my recent posting about that prehistoric big marine 'fish'....

excerpts...
Around the end of the last Ice Age, about 13,000 years ago, animals could roam through subterranean passageways in what is now Mexico. But the creatures who reached the end of those passageways often plunged to their death in a pit descending 180 ft (55 m) into the Earth from which there was no escape. Researchers have been exploring that pit, which is now underwater, and discovering a remarkable collection of fossils.

About three million years ago, thanks to the collision of the Pacific and Caribbean tectonic plates and significant volcanic activity, the Panamanian land bridge emerged. This strip of land not only cut off the Atlantic and Pacific ocean, dramatically altering those giant bodies of water, but it also allowed the intermingling of species between the North American and South American continents

Perhaps most interestingly of all, the pit contains a significant female human skeleton. "This represents the oldest and most complete early human skeleton in the Americas, and she co-existed with a variety of megafauna," said Schubert.
