With more than 70 million specimens, ranging from microscopic slides to mammoth skeletons, the Museum is home to the largest and most important natural history collection in the world.
It all started with Sir Hans Sloane, an 18th century collector, whose collection of 80,000 items was bought by the nation. Over the years, voyages of discovery, such as Cook's epic journey aboard the HMS Endeavour, have boosted our collections. Many benefactors have also made contributions.
The scope of our specimens is simply vast. They include material from the ill-fated dodo, meteorites from Mars and a full-size blue whale skeleton. They cover almost all groups of animals, plants, minerals and fossils, and range in size from cells on slides to whole animals preserved in alcohol.
