The Royal Belgian Institute of Natural Sciences is a museum in the Belgian capital of Brussels dedicated to natural history. Its most important pieces are 30 fossilized Iguanodon skeletons, which were discovered in 1878 in Bernissart. The dinosaur hall of the museum is the world's largest museum hall completely dedicated to dinosaurs. Another famous piece is the Ishango bone, which was discovered in 1960 by Jean de Heinzelin de Braucourt.
Like in most museums, there is a research department and a public exhibit department.
