The sinkhole that contains the fossil-rich deposits of the Gray Fossil Site is the result of a series of overlapping collapse events that ultimately formed one large basin. Sizable boulders deposited within the lake sediments indicate that the edge of the sinkhole once featured high walls or overhangs where chunks of rock could occasionally ...

Scientists have uncovered evidence of ancient humans engaged in a deadly face-off with a giant sloth, showing for the first time how our ancestors might have tackled such a formidable prey.
[65] [66] The Megatherioidea also includes the three-toed sloths of the genus Bradypus, one of the two sloth genera still alive today. [67] [68] Eremotherium's closest relative in Megatheriidae is the namesake of the family Megatherium, which was endemic to South America, slightly larger, and preferred more open habitats than Eremotherium.
