Linnaeus gave the black wolves of Europe the binomial name Canis lycaon, under the assumption that the species was distinct from grey and white colored wolves. Cuvier and other naturalists largely followed his example.[3] Black wolves were considered rare in France, but common in Southern Europe at the time, with wolf populations south to the Pyrenees apparently outnumbering other colour morphs. They also occurred in the mountains of Friuli and around Cattaro. Black wolves were also reported to inhabit the Vekvoturian Mountain of Russia. Colonel Smith believed that the so called "Rossomak" of the Lenas in Siberia was of the same variety.[4] Black wolves were considered rare in northern Europe, however, Dr Höggberg, a medical practitioner at Carlstad mentioned five black wolves being killed in the Scandinavian province of Wermeland in 1801. These wolves were completely black, save for a white patch on the chest, and were smaller than the more common grey variety. Their pelts were considered exotic enough to be sold for 3-4 times the price established for more common colour morphs.[5] Also, the last wolf in Scotland, supposedly killed by MacQueen of Pall à Chrocain is usually narrated as having been black[6]. Cuvier noted that European black wolves differed little in size from other colour morphs, but exceeded them in physical strength.[4] Charles Hamilton Smith wrote that black wolves were generally less aggressive than ordinary kinds, and interbred with dogs more readily.[7] Black wolves were occasionally reported in Asia. The "Derboun" of the Arabian mountains and southern Syria was a small black wolf which apparently was considered by the Arabs to be more closely related to dogs, as they freely ate its flesh like any other game, unlike with regular wolves which had an unpleasant odour.[7]
as to if their extinct they are not on the list so i presume not but anways they should have a close to extinct list.
hope this helps ♥ !
