Real looking dead things freak me out

A recent trip to the Museum of Natural History exposed me to wild animals all around the world. What I couldn't understand was, were they stuffed a la taxidermy style or merely replicated? Should I know this already? Is this a strange question to wonder instead of basking in the intrigue of seeing so many animals in one place? I have to admit. It does help that they weren't alive, better for the picture taking. The kind scientists that arranged the animals were brilliant enough to place them in action poses, to make it almost seem as though this Natural History trip was one to the Zoo.

Night at the Museum anyone? I still have yet to see the 2, I bet it's good!
