A Split Pair Of Colourful Fossilised Ammonites On Stands

A split pair of fossilised ammonites from Madagascar. Ammonites first appeared 415 million years ago in the form of a small, straight shelled creature, known as Bacrites. 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. They lived outside their shells which were infact gaseous chambers that allowed them to rise and sink in the ocean. On their stands they measure 6.5″ high.

“These ammonites that date at least 120 million years old look great when put together as a grouping and more pairs of various sizes can be supplied if required."
