The autopsy is describing the result of wolf-dog hybridization. It had canine dentition. The lower body resembled a wolf, the front resembled a dog. Its rib cage was different than a wolf's. Its coloring was different than a wolf's. It had a squarish, more box-like head resembling a dog but an elongated snout, reminiscent of a greyhound or, in my opinion, a Charnaigre. A Charnaigre was a European hunting dog around during the time of these events. They were incredibly fast, agile, and could leap astounding distances.They pretty much disappeared around the 19th century. Here is a picture:
And here is La Bete du Gevaudan, the ferocious Beast.
See the resemblance?
The Beast was NOT a wolf. Fact. Autopsy proves that. Now which do you trust, the Marin Report suggesting a wolf-dog, or the Natural Museum of History in Paris which has a log of receiving the body of the Beast of Gevaudan in 1766, and that they identified it as a Striped Hyena? That's up to you.
It was either a.) a wolf-dog hybrid
or b.) a striped hyena.
Simple as that.
Are you familiar with Jay Smith's work? He presents a very compelling case that the BoG was, in fact, a wolf or pack of wolves.
