The Fossil corner hosts some of the most unique and well preserved specimens from our collection. This ammonite is a cephalopod, a relatives of octopus and squid that actively swam in Earth’s oceans during the Mesozoic Era 252 – 65 Million years ago. The name “ammonite” comes from the spiral shape of the creature’s shell, which was thought to resemble the tight coil of a ram’s horns. Image by Jim Haggart.
