Red wolves were once distributed throughout the southeastern and south-central United States from the Atlantic Ocean to central Texas, southeastern Oklahoma and southwestern Illinois in the west, and in the north from the Ohio River Valley, northern Pennsylvania, southern New York, and extreme southern Ontario in Canada [2] south to the Gulf of Mexico.

The red wolf is an enigmatic taxon, of which there are two proposals over its origin. One is that the red wolf is a distinct species (C. rufus) that has undergone human-influenced admixture with coyotes. The other is that it was never a distinct species but was derived from past admixture between coyotes and gray wolves, due to the gray wolf ...
The mandibles of canids are buttressed behind the carnassial teeth to crack bones with their post-carnassial teeth (molars M2 and M3). A study found that the modern gray wolf and the red wolf (C. rufus) possess greater buttressing than all other extant canids and the extinct dire wolf. This indicates that these are both better adapted for ...
Mesonychians were depicted as "wolves on hooves" and were the first major mammalian predators, appearing in the Paleocene. [47] Early mesonychians had five digits on their feet, which probably rested flat on the ground during walking ( plantigrade locomotion), but later mesonychians had four digits that ended in tiny hooves on all of their toes ...
In the largest species, the red fox, males weigh between 4.1 and 8.7 kg (9.0 and 19.2 lb), [7] while the smallest species, the fennec fox, weighs just 0.7 to 1.6 kg (1 + 1 ⁄ 2 to 3 + 1 ⁄ 2 lb). [8] Fox features typically include a triangular face, pointed ears, an elongated rostrum, and a bushy tail. They are digitigrade (meaning they walk ...
In May 2011, an examination of 48,000 single nucleotide polymorphisms in red wolves, eastern wolves, gray wolves, and dogs indicated that the red and eastern wolves were hybrid species, with the red wolf being 76% coyote and 20% gray wolf, and the eastern wolf being 58% gray wolf and 42% coyote, finding no evidence of being distinct species in ...
The dhole (/ d oʊ l / dohl; [2] [3] Cuon alpinus) is a canid native to South, East and Southeast Asia.It is anatomically distinguished from members of the genus Canis in several aspects: its skull is convex rather than concave in profile, it lacks a third lower molar and the upper molars possess only a single cusp as opposed to between two and four.
When in such a pose, wolves are referred to as being ravissant. [1] Wolves are also common in German heraldry. The town of Passau (Bavaria) bears a red wolf rampant on a white shield. In Saxony, a black wolf rampant on a yellow shield features on the crest of von Wolfersdorf family. A green wolf grasping a dead swan in its jaws on a yellow ...
