Ammonites are arguably the most widely known fossil, possessing a signature ribbed spiral-form shell. They belong to a group of ancient predators known as cephalopods, which includes living relatives such as the octopus, squid, cuttlefish and nautilus. Ammonites function as excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geological time periods. They lived from the Devonian period up until the catastrophic extinction that wiped out the dinosaurs in the late Cretaceous period.
This gorgeous pair of polished ammonite fossils makes an excellent conversation piece, or gift for the biology or fossil enthusiast in your family or circle of friends. Great for display or experiment in the classroom.
