Description: Ammonites were cephalopods with tightly wound outer shells. These swirly-shelled creatures lived in the Jurassic and Cretaceous periods. Their name originated from the Greek ram-horned god called Ammon. When first born, ammonites had very small shells; as they grew, a new chamber was built to accommodate their bodies. The smaller chamber was then sealed off. In order to move through water, ammonites would expel water through an opening shaped like a funnel, which would propel them forward. These creatures were the predators of their day, eating mussels, fish, and fellow cephalopods. Their sturdy shells made ammonites more likely to leave a fossil as they were able to survive under sediment for millions of years! They became extinct at the end of the Cretaceous when a huge asteroid hit the Earth causing the extinction of many of the animals including the dinosaurs.This pair each measures approx. 4 1/2" across and together weigh 605g. The colors and sparkling crystal cavities as well as the iridescent sheen and intricate patterns of the outer shell makes this pair a wonderful addition to any collection.
