This piece is inspired by the scene from Predator 2, where you see a skull resembling a xenomorph from the alien franchise, mounted on the wall of a trophy room.
It measures 26 inches long. And is the most authentic and realistic one out there - using ivory detailing rather than grey for more pronounced realism.
The stand is modified with a rod for pitch stability when the skull is mounted. So the skull can still be removed. Otherwise it would just flop all the way back, not fully suspended in air.
