caption: The image shows a pair of white shells from the Neolithic period, known as seraphididae, on a black surface with a box and a piece of paper with text written on it. The shells have a smooth, glossy finish and are arranged in a symmetrical pattern. The box is rectangular in shape and has a lid that can be opened to reveal the shells inside. The text on the paper is written in a bold font and is likely a description of the shells.
