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]
Ancient footprints from White Sands National Park The White Sands fossil footprints are a set of ancient human footprints discovered in 2009 in the White Sands National Park in New Mexico. In 2021 they were radiocarbon dated , based on seeds found in the sediment layers, to between 21,000 and 23,000 years ago. [ 1 ]
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 ...
Dozens of mammoths were trapped in a South Dakota sinkhole over 100,000 years ago.. A bulldozer uncovered the first fossil 50 years ago, and experts have been finding bones ever since.
[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.
Ground sloths are a diverse group of extinct sloths in the mammalian superorder Xenarthra. They varied widely in size with the largest, belonging to genera Lestodon, Eremotherium and Megatherium, being around the size of elephants. Ground sloths represent a paraphyletic group, as living tree sloths are thought to have evolved from ground sloth ...
