Step-by-step explanation:
Bernissart is famous as a graveyard of Iguanodon. In 1878, a significant discovery was made in Bernissart, Belgium, where a large number of Iguanodon skeletons were found in a coal mine. The Iguanodon was a genus of herbivorous dinosaurs that lived during the Early Cretaceous period, and this discovery was remarkable because it provided extensive insight into the species, including how they may have lived and looked. The site provided paleontologists with a wealth of information, leading to a leap in understanding dinosaur anatomy and behavior.
