English: This is a stereograph showing some fossils and artifacts belonging to the Smithsonian collection, in Washington, D.C., USA. This image was captured in the original United States National Museum, now called the Arts and Industries building, before 1910 when these collections moved to their current building, the National Museum of Natural History. At least one skeletal mount of a Megatherium (a cast, mounted and sold to the Smithsonian by Henry Augustus Ward in the 1870s or 1880s) and one skeletal mount and full-scale model of a Megaloceros are also seen in the image. Both skeletons are casts, not original fossilised bone, and only one of them, the Megaloceros, still is nowadays kept in the Smithsonian collections. The Megatherium cast was too damaged after being in contact with the public through years, and this Smithsonian Megatherium had to be discarded (or maybe even destroyed) before 1910, when the original national museum moved to its current building. Henry A. Ward produced this Megatherium cast out of original bones preserved in London by the British Museum of Natural History. The original bones were never mounted but Richard Owen mounted a cast in 1861, still on display in the Natural History Museum in London.
