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 ...
The largest deer of all time was the broad-fronted moose (Cervalces latifrons). The extinct Irish elk (Megaloceros giganteus) and the stag-moose (Cervalces scotti) were of similar size to the Alaskan moose. However, the Irish elk could have antlers spanning up to 4.3 m (14 ft) across, about twice the maximum span for a moose's antlers. [27]
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 order Carnivora is the sixth largest order of mammals, [22] comprising at least 279 species on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. Carnivorans exhibit a wide array of body plans, varying greatly in size and shape.
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 ...
One of the largest known perissodactyls, and the second largest land mammal (see Palaeoloxodon namadicus) of all time was the hornless rhino Paraceratherium. The largest individual known was estimated at 4.8 m (15.7 ft) tall at the shoulders, 7.4 m (24.3 ft) in length from nose to rump, and 17 t (18.7 short tons) in weight.
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.
