The London Natural History Museum was much more of a typical natural history museum than The Dead Zoo in Dublin. I went in what I later learned was actually a side entrance, and even that was pretty impressive.
This natural history museum was pretty standard, with the story about the solar system and the history of the earth, as well as the geology lesson (sedimentary, igneous, and metamorphic rocks anyone?), with all the rocks and minerals. I did find out that Kryptonite is real! Scientists found it in Serbia.
They also had their own taxidermied animals (Dodo birds were huge!), as well as a giant moving scorpion, and a couple of dinosaurs!
