This is a list of the largest rodents. Rank Common name Scientific name Status Maximum body mass [kg (lb)] Image Notes 1: Giant pacarana: Josephoartigasia monesi:
Paraceratherium is one of the largest known land mammals that have ever existed, but its precise size is unclear because of the lack of complete specimens. [4] Its total body length was estimated as 8.7 m (28.5 ft) from front to back by Granger and Gregory in 1936, and 7.4 m (24.3 ft) by the palaeontologist Vera Gromova in 1959, [ 33 ] but the ...
This makes J. monesi the biggest rodent ever discovered. It was much larger than J. magna , giant hutia or the largest living rodent, the capybara , which averages 60 kg (130 lb). J. monesi also had a massive bite force of approximately 1,400 N (310 lb f ) at the incisors (on par with large carnivores) and 5,000 N (1,100 lb f ) at the third ...
It grew over 8 ft (2.4 m) in length and weighed roughly 60 to 100 kg (130 to 220 lb), also making it one of the largest rodents to ever exist. The largest species in the squirrel family is the hoary marmot (Marmota caligata) of the Pacific Northwest, at up to 13.5 kg (30 lb) and 0.8 m (2.6 ft) long. [118] [119]
The elephant Palaeoloxodon namadicus has been suggested to have been the largest land mammal ever, based on a particularly large partial femur which was estimated to have belonged to an individual 22 t (24.3 short tons) in weight and about 5.2 m (17.1 ft) tall at the shoulder, though the author of the estimate said that this was speculative and ...
The largest land mammal extant today is the African bush elephant. The largest extinct land mammal known was long considered to be Paraceratherium orgosensis, a rhinoceros relative thought to have stood up to 4.8 m (15.7 ft) tall, measured over 7.4 m (24.3 ft) long and may have weighed about 17 tonnes.
Tango was brought to the zoo in 2010 after he was found wandering the parking lot of the Falls mall in South Miami-Dade. Patagonian maras live on average to about 14 years old in the wild.
Assuming it was about 20% larger, Larramendi calculated an extrapolated femur length of 1.9 metres (6.2 ft) and a speculative size estimate of 5.2 metres (17.1 ft) tall at the shoulder and 22 tonnes (49,000 lb) in body mass, which if correct would make P. namadicus possibly the largest land mammal ever, exceeding even paraceratheres in size.
