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 ...
Megatherium (/ m ɛ ɡ ə ˈ θ ɪər i ə m / meg-ə-THEER-ee-əm; from Greek méga 'great' + theríon (θηρίον) 'beast') is an extinct genus of ground sloths endemic to South America that lived from the Early Pliocene [1] through the end of the Late Pleistocene. [2]
The Page–Ladson archaeological and paleontological site is a deep sinkhole in the bed of the karstic Aucilla River (between Jefferson and Taylor counties in the Big Bend region of Florida) that has stratified deposits of late Pleistocene and early Holocene animal bones and human artifacts.
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.
By Matthew Stock BOURNEMOUTH, England (Reuters) - 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 ...
The earliest megatheriid in North America was Sibotherium which arrived 5.3 million years ago, after crossing the recently formed Panamanian land bridge. At more than five tons in weight, 6 metres (20 ft) in length, and able to reach as high as 5.2 metres (17 ft), Eremotherium when fully erect was taller than an African bush elephant bull.
Over the past 15 years, sinkhole damage costs an average of $300 million a year in the United States. There are several ways to identify a sinkhole in progress.
[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.
