The figure on the slab could plausibly be a shaman with an exposed penis or be dressed up as an animal, in which case the protuberance could be a tail.

Last I checked, one is in the front, the other is in the back... Can't the scientist figure out which one it is?

“....be a shaman with an exposed penis ….”

That’s how you tell if your shaman is any good!
