The dire wolf (Aenocyon dirus [10] / iː ˈ n ɒ s aɪ. ɒ n ˈ d aɪ r ə s /) 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 ...
As of 2018, the global gray wolf population is estimated to be 200,000–250,000. [1] Once abundant over much of North America and Eurasia, the gray wolf inhabits a smaller portion of its former range because of widespread human encroachment and destruction of its habitat, and the resulting human-wolf encounters that sparked broad extirpation.

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.
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 CDFW confirmed the wolves had established territory in California with footage from a trail camera in 2015. Biologists believed the two adult wolves migrated into the state from southern Oregon. [20] One of the grown-up pups was found in northwestern Nevada in 2016, the first wolf verified in Nevada in nearly 100 years.
It looks like this shark is straight out of the movie "Jaws." Marine biologist Hoyos Padilla recorded this incredible footage showing the biggest shark ever caught on camera, which is 20 feet long.
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 ...
