Mammoth skull, 40,000 years old, put up for auction in Évreux. Auctioneer: "It’s my first mammoth skull,” says Nicolas Fierfort.

The tip of its tusks, 98 centimeters long, is nevertheless broken, but the fracture adds history to this skull. A dinosaur tooth, butterflies, a parrotfish, a sperm whale eardrum and “magnificent” megalodon tails are also on the menu.
