The Royal Belgian Institute of Natural Sciences is part of the Belgian Science Policy Office.

It is located close to the Berlaymont Palace, the headquarters of the European Commition, the main executive power of the European Union.

The access to the museum is on the southern side of Leopold Park in Rue Vautier.

The building is divided into three levels and 14.000 m2 of exibitions divided in a minerary show, the gallery of life with several hundreds of taxidermized fishes, birds and mammals, and a magnificent area dedicated to evolution and dinosaurs.

The latter is particularly devoted to Iguanodon bernissartensis, a bipedal Ornitischian dinosaur. The best representative discovery of such large herbivorous was in the Belgian site of Bernissart, where almost 30 individuals of different ages had been discovered buried together, with anatomically connected bodies, probably a consequence of an ancient catastrophic event that driven them to die. Such discovery allowed researchers to assume that Iguanodon lived in packs.

The importance of such discovery in the deep galleries of a coal mine was so unexpected and so important that the animal have been chosen as official logo of the Museum of Natural Sciences.

Iguanodon was a massive and agile animal, with a short beak-like on the mouth, robust hindlimbs and rather long forelimbs. Hands had 5 digits, with a thumb reduced in number of phalanxes but quite prensile, and with a long distal claw. On the other side, last finger was reduced. Second, third and fourth fingers probably had hoofs.
