The image shows a display case with six fossilized shells on it. The shells are arranged in a row and are of different sizes and shapes. Each shell has a unique design on its surface, with some having a spiral pattern and others having a smooth texture. The display case is made of wood and has a beige background. Below the display case, there is a text in Chinese that translates to "Shell tools of Ken-tong site (Pingtong)". The text also mentions that the shells are from the Middle Neolithic Age, Ken-Tong Culture, and are approximately 500-3,000,000 B.P.
