£ 12.60
Genuine Mantelliceras saxbii Ammonite FossilThis listing is for a genuine Mantelliceras saxbii ammonite fossil from the
Lower Cenomanian stage of the Cretaceous, collected from Steyning, West Sussex, United Kingdom. This is a carefully chosen fossil specimen, and the photo shows the actual fossil you will receive. Full sizing and scale details can be seen in the photograph.The fossil includes a Certificate of Authenticity lifetime guarantee generic card, giving confidence that this is a genuine natural fossil specimen suitable for collectors, educational use, display, gifting, or as an addition to a Cretaceous ammonite collection.Geological Age and LocalityThis ammonite comes from the Lower Cenomanian, an important interval at the beginning of the Cenomanian stage of the Cretaceous. Fossils from this age are highly valued because the Cenomanian represents a major period of marine expansion, when warm shallow seas covered large areas of what is now southern England.The Steyning area of West Sussex lies within a classic southern English Cretaceous fossil region, known for marine deposits formed in ancient chalk and marl seas. During the time this ammonite lived, the area would have been part of a warm, open marine environment rich in shelled invertebrates, planktonic life, and predatory marine reptiles. Fine calcareous sediments settled on the sea floor and helped preserve the remains of ammonites and other marine organisms.Fossil Type and Species DetailsMantelliceras saxbii is an extinct ammonite species belonging to the ammonoid cephalopods, a group of marine molluscs related to modern squid, octopus, and nautilus. Ammonites had coiled chambered shells and were active swimmers in prehistoric seas. Their shells are among the most recognisable and collectible fossils from the Mesozoic Era.Taxonomically, Mantelliceras is placed within the Order Ammonitida, Superfamily Acanthoceratoidea, and Family Acanthoceratidae. The species Mantelliceras saxbii was formally described by Daniel Sharpe in 1857. It is an important Cenomanian ammonite and is associated with Lower Cenomanian biostratigraphy, including the Mantelliceras mantelli Zone and Mantelliceras saxbii Subzone.Shell Form and Ammonite FeaturesMantelliceras ammonites are known for their distinctive ribbed shells. Typical features include a moderately coiled shell, visible whorls, a defined umbilicus, and strong ribs running across the flanks. These ribs helped strengthen the shell and are one of the key visual features that make this genus attractive to collectors.The shell form of Mantelliceras saxbii reflects an active marine cephalopod adapted to life in the Cretaceous seas. Like other ammonites, it would have used its chambered shell for buoyancy control, allowing it to move through the water column while hunting or scavenging for food. Its preserved shell provides a direct link to the marine ecosystems of Cretaceous Britain.Collector AppealThis Mantelliceras saxbii fossil ammonite is a desirable specimen for collectors interested in British fossils, Cretaceous ammonites, Sussex geology, and classic marine fossils. Its Lower Cenomanian age, named species identification, and West Sussex locality make it a particularly interesting piece for both display and study.The specimen has been selected for its visual and scientific interest. As with all natural fossils, small variations, natural wear, matrix, surface texture, and preservation features are part of its authenticity and character. The photograph shows the exact fossil being offered, so you can buy with confidence knowing the pictured specimen is the one supplied.Authenticity and PresentationThis fossil is a genuine specimen and is supplied with a Certificate of Authenticity lifetime guarantee generic card. It is ideal for fossil collectors, geology enthusiasts, students, teachers, natural history displays, or anyone looking for a real piece of Cretaceous marine history from the United Kingdom.
