This specimen is accompanied by an acrylic display stand.
Ammonites had a strong existence; they survived most major extinction events. With every extinction event, there were some ammonite species that came extinct and those that survived. The last ammonites got extinct in the same extinction event as the dinosaurs, approximately 65 million years ago. Some of the ammonite fossils have been found with triangular holes in them, believed that these were puncture holes created by mosasaurs (large marine reptiles that existed at that time).
History indicates that humans have always been fascinated by ammonites. In our times, the different species of ammonites that are found in the rocks, were and still are, a key to biostratigraphy (the study of different layers of rock and their age estimation). And definitely they are still much appreciated for their spectacular and beautiful features.
