Illustration of the first specimen of Megatherium americanum from 1796 Life illustration of Megatherium americanum from 1863, depicting it with a short trunk. The earliest specimen of Megatherium americanum was discovered in 1787 by Manuel de Torres, a Dominican friar and naturalist, from a ravine on the banks of the Lujan River in what is now northern Argentina, which at the time was part of ...
The Paleontological Museum Megatherium (Spanish: Museo Paleontológico Megaterio) is a museum in the province of Santa Elena in Ecuador, located in the Universidad Estatal Península de Santa Elena. It is considered the first museum of paleontology in Ecuador .
The group includes the heavily built Megatherium (given its name 'great beast' by Georges Cuvier [4]) and Eremotherium. An early genus that was originally considered a megatheriid, the more slightly built Hapalops, reached a length of about 1.2 metres (3.9 ft). The nothrotheres have recently been placed in their own family, Nothrotheriidae. [5]
The humerus widened considerably downwards and measured between 13.6 and 16.2 cm at the end of the joint (elbow joint). The ratio of the lower width to the total length of the bone thus corresponded approximately to that of Megatherium and was significantly larger than in Pyramiodontherium and Megatheriops. Most of the other long bones are ...
A number of kill sites are known for ground sloths in the Americas, these include Campo Laborde in the Pampas of Argentina, where an individual of Megatherium americanum was butchered at the edge of a swamp, dating to approximately 12,600 years Before Present (BP), [63] with another potential Megatherium kill site being Arroyo Seco 2 in the ...
Eremotherium laurillardi skeleton at the Smithsonian National Museum of Natural History. Eremotherium was slightly larger than the closely related Megatherium in size, reaching an overall length of 6 metres (20 ft) and a height of 2 metres (6.6 ft) while on all fours, possibly up to 4 metres (13 ft) when it reared up on its hind legs.

Within the Megatheriidae there are two (possibly three) subfamilies; the Megatheriinae and the Planopsinae. The phylogenetically older group is represented by the Planopsinae from the Lower and Middle Miocene.
Priestia megaterium [1] (Bacillus megaterium prior to 2020) [2] is a rod-like, Gram-positive, mainly aerobic, spore forming bacterium found in widely diverse habitats. [3] [4] It has a cell length up to 100 μm and a diameter of 0.1 μm, which is quite large for bacteria. [5]
