[19], The species Megatherium filholi Moreno, 1888 of the Pampas, previously thought to be a junior synonym of M. americanum representing juvenile individuals, was suggested to be a distinct valid species in 2019. [14], The species Megatherium (Pseudomegatherium) tarijense, appears to be a junior synonym of M. americanum, and merely a small individual. [25] A kill site dating to around 12,600 BP is known from Campo Laborde in the Pampas in Argentina, where a single individual of M. americanum was slaughtered and butchered, which is the only confirmed giant ground sloth kill site in the Americas.

The oldest (and smallest) species of Megatherium is M. altiplanicum of Pliocene Bolivia. [A] Carbon isotope analysis has found that Megatherium has isotope values similar to other megafaunal herbivores such as mammoths, glyptodonts, and Macrauchenia, and significantly unlike omnivorous and carnivorous mammals, suggesting that Megatherium was an obligate herbivore. You hike down, down, and even farther down into the “Bowl” of the forest: a deep, biodiverse lowland of the Tambopata National Reserve.

The Sumerians mention a land in the West called Kuga-ki where they mined valuable metals. [33] The use of bioclimatic envelope modeling indicates that the area of suitable habitat for Megatherium had shrunk and become fragmented by the mid-Holocene. [9], According to one study, Megatherium was probably mostly hairless (like modern elephants) due to its large size giving it a small surface-area-to-volume ratio, making it susceptible to overheating. While it has been suggested that the giant sloth may have been partly carnivorous, this is a controversial claim. [11] Megatherium also possessed the narrowest muzzle of all ground sloths from the Pleistocene, possibly meaning it was a very selective eater, able to carefully pick and choose which leaves and twigs to consume.

The family to which Megatherium belongs, Megatheriidae, is related within superfamily Megatheroidea to the extinct families Nothrotheriidae and Megalonychidae, and to living three-toed sloths of family Bradypodidae, as deduced recently from collagen[22] and mitochondrial DNA[23] sequences obtained from subfossil bones. Only a few other land mammals equaled or exceeded M. americanum in size, such as large proboscideans (e.g., elephants) and the giant rhinoceros Paraceratherium. Andean bears' thick coats are usually either black or brown, occasionally tinged with red. [3] It is best known for the elephant-sized type species M. americanum, sometimes called the giant ground sloth, or the megathere, native to the Pampas through southern Bolivia during the Pleistocene.

Xenarthrans were largely unaffected and continued to thrive in spite of competition from the northern immigrants. [12] In Megatherium, the stylohyal and epihyal bones (parts of the hyoid bone which supports the tongue and is located in the throat) were fused together, and the apparatus lies farther upwards the throat, which, together with the elongated, steeply inclined mandibular symphysis, indicates a relatively shorter geniohyoid muscle and thus more limited capacity for tongue protrusion.

[7][8] It is the largest-known ground sloth, as big as modern elephants, and would have only been exceeded in its time by a few species of mammoth.

The giant ground sloth was a herbivore, feeding on leaves such as yuccas, agaves, and grasses. The oldest records of M. americanum are from the latter half of the Middle Pleistocene, around 0.4 Ma.[25].
