Before you even ask, no, it probably isn’t a dire wolf. Dire wolves were real, if not magical, things, but, according to the scientists studying it, this probably wasn’t one of them. The giant severed wolf head was found in 2018, but images were only recently released.
The giant Pleistocene wolf head was discovered, buried in the permafrost, by a local in Eastern Siberia. The wolf would have been between two and four years old when it was decapitated by, what I have to assume was, some Pleistocenic badass. Whoever they were, it seems they never got to take their trophy home, since the wolf’s fur, teeth, and brain were preserved intact. The head is 40 cm long and, for comparison, your average modern wolf’s head is around 28 cm, with the dire wolf’s coming in around 31 cm.
