The image shows a display case with three pieces of fossilized shells on it. The shells are arranged in a triangular formation, with the largest one in the center and two smaller ones on either side. All three shells appear to be made of a light-colored material, possibly bone or a similar material. The shell on the left is slightly larger than the one on the right, and the one in between is slightly smaller. The display case is made of cardboard and has a black label at the bottom with Chinese characters. The background is a beige-colored surface.
