During the Ice Age, a group of giant ground sloths died together after swallowing their own feces in a contaminated pool of shallow water.

Scientists discovered the bones of nearly two dozen ground sloths (Eremotherium laurillardi) in a pit at a fossil-rich site called Tanque Loma in southwestern Ecuador. The bone bed dates to the end of the Pleistocene epoch (around 2.6 million to 11,700 years ago) and holds thousands of bones from large mammals.
