Ikran Skull. maybe.

I was recently watching predator 2 (I know Cameron had nothing to do with the movie) but, in one of the final scenes in the predator ship it shows a wall of skulls which include a human skull and and alien skull. However towards to bottom left of the wall I think, there's a skull which, to me, looks curiously like an ikran. The shot didn't last long so I'm not completely sure, but I like all you people to watch it and post thoughts below.

hmmm good spotting on that one. I haven't watched the movie yet but im searching for that clip to prove that you could be right.

It kind of looks like it, but there are a couple differences. That shot was just to show that there was a connection between Aliens and the Predator.

Yeah, it was a random alien (Not from alien) skull to show that the predators many different species including the humans and aliens (from aliens.)
