The dire wolf (Aenocyon dirus[10] / iːˈnɒsaɪ.ɒn ˈdaɪrəs /) is an extinct canine. The dire wolf lived in the Americas (with a possible single record also known from East Asia) during the Late Pleistocene and Early Holocene epochs (125,000–9,500 years ago). The species was named in 1858, four years after the first specimen had been found.
The largest dinosaurs, and the largest animals to ever live on land, were the plant-eating, long-necked Sauropoda. The tallest and heaviest sauropod known from a complete skeleton is a specimen of an immature Giraffatitan discovered in Tanzania between 1907 and 1912, now mounted in the Museum für Naturkunde of Berlin. It is 12–13.27 m (39.4 ...
Diet. [] Location of a dog's carnassials; the inside of the 4th upper premolar aligns with the outside of the 1st lower molar, working like scissor blades. Isotopic bone collagen analysis of the specimens indicated that Pleistocene wolves ate horse, bison, woodland muskox, and mammoth — i.e., Pleistocene megafauna.
The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids ...
The Bohemian wolf is an extinct short-legged wolf that first appeared 800,000 years ago (MIS 20, the Rhumian Interglacial of the early Cromerian stage, Middle Pleistocene) and once inhabited what was part of the mammoth steppe. It is proposed as the ancestor of Canis lupus mosbachensis.
The maned wolf is the tallest of the wild canids; its long legs are likely an adaptation to the tall grasslands of its native habitat. [18] Fur of the maned wolf may be reddish-brown to golden orange on the sides with long, black legs, and a distinctive black mane. The coat is marked further with a whitish tuft at the tip of the tail and a ...
[42] [169] The largest wolf (Canis lupus) subspecies ever existed in Europe is the Canis lupus maximus from the Late Pleistocene of France. Its long bones are 10% larger than those of extant European wolves and 20% longer than those of C. l. lunellensis. [170] The Late Pleistocene Italian wolf was morphometrically close to C. l. maximus. [171]
The northwestern wolf (Canis lupus occidentalis), also known as the Mackenzie Valley wolf, [ 5 ]Alaskan timber wolf, [ 6 ] or Canadian timber wolf, [ 7 ] is a subspecies of gray wolf in western North America. Arguably the largest gray wolf subspecies in the world, it ranges from Alaska, the upper Mackenzie River Valley; southward throughout the ...
