WCIF: Skeletons

Basically I want to build a Natural & Unnatural History Museum. So I've been trying to find various skeletons. Suffice it to say that I haven't had much luck.

Any kinds of skeletons or skeleton related stuff would be helpful; be it fossils, skulls, whatever. Real creatures, sci-fi creatures, and fantasy creatures are all welcome.

And if I could get a lead on some Taxidermy animals or maybe some specimen jars, that would be greatly appreciated. Oh, and also insect collections. 

Thanks for the help!
