i don't think its a real species(duh) but many slapped together no photo shop other than bad shadowing id say just a good taxidermist with some time and spare parts lying around
they have a yearly competition for stuff like this although i don't remember what its called
i do see where someone has blacked out the throat so you cant see the inside why they made that straight line on the k9 is beyond me but what ever
the k9 teeth do look baboon as for the molars they look to have come from something a little larger than a deer small elk maybe
