Although the sculptor, Conal McCabe, called this work merely "Fossil", it is very clearly the depiction of an ammonite. It is made of Cadeby stone and originally stood on a plinth on the ground outside Beveridge House. However, vandals managed to lever the entire sculpture away from its setting, chipping it while doing so. It has now been reset into the side wall of the Baptist Chapel.

Ammonites look like tightly-coiled, flattened snail shells but in fact, were relatives of squids, octopi and cuttlefish. Their thin soft bodies were coiled inside the compartmented shell with the head and tentacles trailing outside as they swam backwards. They lived in the warm shallow seas that covered Barrow between 180 to 200 million years ago. There are many ammonite fossils in Barrow limestone.
