The Museum of Natural Sciences of Belgium (, ) is a museum dedicated to natural history, located in Brussels, Belgium. The museum is a part of the Royal Belgian Institute of Natural Sciences. Its most important pieces are 30 fossilised Iguanodon skeletons, which were discovered in 1878 in Bernissart, Belgium. 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 in the Belgian Congo. The museum also houses a research department and a public exhibit department. History The Museum of Natural Sciences was founded on 31 March 1846, as a descendant of the Musée de Bruxelles of 1802. It was based on the collection established by Prince Charles Alexander of Lorraine, dating from the 18th century. The scientist and politician Bernard du Bus de Gisignies became the first director of the museum in 1846, and on this occasion, he donated 2,474 birds from his own collection to the museum. In 1860, during the construction of new fortifications around Antwerp, several fossils were found, mainly of whales, and they were acquired by the museum. The museum also obtained the skeletons of a bowhead whale (Balaena mysticetus) and a young blue whale (Balaenoptera musculus), which are still on display today. The same year, the skeleton of a mammoth was unearthed near Lier, in Antwerp, Belgium, and due to the prompt action of the archaeologist François-Joseph Scohy, it was preserved and brought to the museum, where it has been exhibited since 1869. At that time, the only other skeleton of a mammoth on display was in the museum of Saint Petersburg in Russia. In 1878, the largest find of Iguanodon fossils to date occurred in a coal mine at Bernissart, in Hainaut, Belgium. At least 38 Iguanodon (Iguanodon bernissartensis) skeletons were uncovered, at a depth of , of which 30 were brought back to the museum and put on display. They were mounted by Louis Dollo and set the standard that was followed for over a century. Found alongside the Iguanodon skeletons were the remains of plants, fish, and other reptiles, including the crocodyliform Bernissartia. Between 1889 and 1891, the museum moved from its original home at the Palace of Charles of Lorraine into a former convent located on the heights of the park. The building quickly became too
