caption: The image shows a fossil of an ammonite on display in a museum, with a rock in the center and a board with text at the bottom. The fossil is a photo of the ammonite, which is a large, oval-shaped shell with a spiral pattern of interlocking ridges and grooves. The rock is a light gray color and has a smooth, glossy finish. The text on the board is written in black ink and is likely a description of the fossil.
