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 ...
Little Salt Spring is a feature of the karst topography of Florida, specifically an example of a sinkhole.It is classified as a third magnitude spring. [4] The numerous deep vents at the bottom of the sinkhole feed oxygen-depleted groundwater into it, producing an anoxic environment below a depth of about 5 m (16.4 ft). [4]
Based on fossil trackways and the anatomy of its inner ear, which is considerably different from living sloths and more similar to those of armadillos, species of Megatherium, while probably not capable of moving at considerable speed due to limitations of their skeletal anatomy (with one study estimating a max speed of approximately 2.2 metres ...

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.
The dung has given information about what the environment and vegetation of the area was because the sloth was a herbivore. This ancient plant eater survived on capers, mustards, grasses, agave, yucca, phacelia, borages, mints, grape, globemallow, saltbushes and ephedra. [6]
Two-thirds of the world’s more than 300 sinkholes are in China, scattered throughout the country’s west - with 30 known tiankeng, Guangxi province in the south has more of of them than ...
Natural Trap Cave is a pit cave in the Bighorn Mountains, in northern Wyoming, United States.Excavations in the cave are an important source of paleontological information on the North American Late Pleistocene, due to a rich layer of fossils from animals that became trapped in the cave.
