Hogs and pigs don't have their teeth configured like that. Hogs have molars and tusks and pigs have teeth in the very front, small canines, and molars. And I don't think I've ever seen a pig that had the ears flopped over either. Although the beak like bone is somewhat similar to what's behind the pigs nose.
Probably fake as people are saying that it came from the water yet I see no gills or anything else for that matter implying that it lived in the water. It just doesn't have the skeletal structure to be a good swimmer. There's a reason fish have fins and not legs.
If it's not fake, it's probably a product of the gov't test facility like mentioned in the article.
