These are creatures that lived in the seas between 240 - 65 million years ago, when they became extinct along with the dinosaurs. These sea creatures first appeared 415 million years ago. They quickly evolved into a variety of shapes and sizes including some shaped like hairpins. During their evolution the ammonites faced no less than three catastrophic events that would eventually lead to their extinction. The first event occurred during the Permian (250 million years ago), where only 10% survived. These surviving species went on to flourish throughout the Triassic, however at the end of this period (206 million years ago) they faced near extinction, when all but one species survived. This event marked the end of the Triassic and the beginning of the Jurassic, during which time the number of ammonite species grew once more. The final catastrophe occurred at the end of the Cretaceous period when all species were annihilated and the ammonites became extinct. This event apparently coincided with the death of the dinosaurs.
Most ammonite shells are coiled, and all contain a series of linked chambers. The body of the ammonite was contained within the large final, open-ended section called the living or head chamber, from which the tentacles were extended to catch prey. The opening of the shell - called the aperture - was possibly covered by a protective shield that could shut to protect the ammonite from other predators.
