The fourth gallery depicts the existance of the famous Dodo in mauritius in early years .A model of the Dodo, the centrepiece of the museum, is displayed in this gallery. The skeleton of the Dodo, collected by E. Thirioux, a barber, in 1900, is unique in the sense that all the bones come from one individual bird. The extinction of the Dodo, within 80 years of its discovery, made man realize for the first time that he could induce the extinction of plants and animals. The oldest stuffed specimen in the museum is the Mauritian Dutch Pigeon which was killed in 1826. A skeleton of the Rodrigues Solitaire, discovered in Caverne Patate in 1900, is also exhibited in this gallery. Other important scientific treasures in the museum are the unique and incomplete skeletons of the Mauritian Red Rail.
