Pontolis reached more than 4 m (13 ft) in body length, [4] rivaling the extant southern elephant seal as the largest pinniped [5] and member of the order Carnivora of all time. Weight estimates for Pontolis range between 2,000 to 4,000 kg (4,400 to 8,800 lb).
This meant that the plantigrade Palaeonictis was at least a part-time scavenger. The biggest species, Palaeonictis peloria (meaning "terrible ancient weasel") is known from an incomplete jaw that must have measured over 20 centimetres (7.9 in) in length. This animal was the largest carnivore in its ecosystem.
The largest New World monkey is the southern muriqui (Brachyteles arachnoides), up to 15 kg (33 lb) and 1.6 m (5.2 ft) in total length. [107] The largest lemur is the indri (Indri indri) which can weigh up to 12 kg (26 lb) and 90 cm (3.0 ft) in total length, though one fossil lemur, Archaeoindris, was gorilla-sized at 200 kg (440 lb).

Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. 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.
The largest known metatherian carnivore, Proborhyaena gigantea, apparently reached 600 kilograms (1,300 lb), also close to this limit. [10] A similar theoretical maximum size for mammalian carnivores has been predicted based on the metabolic rate of mammals, the energetic cost of obtaining prey, and the maximum estimated rate coefficient of ...
The blue whale is the largest mammal of all time, with the longest known specimen being 33 m (108.3 ft) long and the heaviest weighted specimen being 190 tonnes. [ 15 ] [ 60 ] [ 61 ] The extinct whale species Perucetus colossus was shorter than the blue whale, at 17.0–20.1 meters (55.8–65.9 ft) but it is estimated to have rivaled or ...
By far the largest carnivore in its environment, T. rex was most likely an apex predator, preying upon hadrosaurs, armored herbivores like ceratopsians and ankylosaurs, and possibly sauropods. [207] Enamel δ 44/42 Ca values also suggest the possibility that T. rex occasionally fed on carcasses of marine reptiles and fish washed up on the ...
