Update/Context from the University: The University Services of Laghouat has officially clarified this. It turns out these are the remains of a bull that first-year Veterinary students were dissecting as a "scientific experiment."The administration issued a statement saying the room was actually broken into and filmed while students were away to make it look like something else and "mislead the public." Since they are now pursuing legal action against anyone sharing the photos for "violating privacy" and spreading false data, I’m updating this to reflect the official word.It’s definitely a bizarre place and way to do a dissection, but that’s the "scientific" explanation behind the mess.
