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.
[126] [134] [125] [129] There possibly existed a panmictic wolf population with gene flow spanning Eurasia and North America until the closing of the ice sheets. [126] [135] [129] Once the sheets closed, the southern wolves were isolated and north of the sheets only the Beringian wolf existed. The land bridge became inundated by the sea 10,000 ...
The Beringian wolf was similar in size to the modern Alaskan Interior wolf (C. l. pambasileus). [8] The largest northern wolves today have a shoulder height not exceeding 97 cm (38 in) and a body length not exceeding 180 cm (71 in). [30] The average weight of the Yukon wolf is 43 kg (95 lb) for males and 37 kg (82 lb) for females.
[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 wolf, whose rich mammoth-like fur and impressive fangs are still intact, was fully grown and aged from two to four years old when it died. 'This is a unique discovery of the first ever remains of a fully grown Pleistocene wolf with its tissue preserved.
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 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 ...
