The following list contains the largest terrestrial members of the order Carnivora, ranked in accordance to their maximum mass. List. Rank Common name
Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores. Carnivora is the fifth largest order of mammals and currently comprises 291 extant species, which are grouped into 131 genera.
The largest carnivorous synapsid was Anteosaurus at 5–6 m (16–20 ft) and 500–600 kg (1,100–1,300 lb). [67] Caseasaurs (Caseasauria) The herbivorous Alierasaurus was the largest caseid and the largest amniote to have lived at the time, with an estimated length around 6–7 m (20–23 ft). [68]
The largest and most diverse family of carnivores, the mustelids, reaches their maximum size (by mass) in the sea otter (Enhydra lutris) of the North Pacific coasts, at up to 54 kg (119 lb), and (by length) the giant otter (Pteronura brasiliensis) of the Amazonian rainforests, at up to 2.4 m (7.9 ft) in total.
The largest carnivorous non-mammalian synapsids was the dinocephalian Anteosaurus, which was 5–6 m (16–20 ft) long, and weighed 500–600 kg (1,100–1,300 lb). [16] [17] Fully grown Titanophoneus from the same family Anteosauridae likely had a skull of 1 m (3.3 ft) long. [17]
The fossa is the largest mammalian carnivore on Madagascar and has been compared to a small cougar, as it has convergently evolved many cat-like features. Adults have a head-body length of 70–80 cm (28–31 in) and weigh between 5.5 and 8.6 kg (12 and 19 lb), with the males larger than the females.
The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
Spinosaurus is the longest known terrestrial carnivore; other large carnivores comparable to Spinosaurus include theropods such as Tyrannosaurus, Giganotosaurus and the coeval Carcharodontosaurus. The most recent study suggests that previous body size estimates are overestimated, and that S. aegyptiacus reached 14 m (46 ft) in length and 7.4 t ...
