£ 10.20
Genuine Polyplectus bicarinatum Ammonite Fossil from Mende, FranceThis Polyplectus bicarinatum ammonite fossil is a genuine Lower Jurassic
specimen from Mende, Lozère, France. It dates from the Toarcian Stage of the Early Jurassic, making it an attractive and scientifically interesting fossil for collectors of ammonites, French fossils, Jurassic marine life and natural history specimens.The photograph shows the actual fossil you will receive, so this is a carefully chosen individual specimen rather than a stock image or representative example. For full sizing and visible condition, please see the listing photo. This fossil includes a Certificate of Authenticity lifetime guarantee generic card.Fossil Type and Species InterestPolyplectus bicarinatum is a Lower Jurassic ammonite, an extinct marine cephalopod related to modern squid, cuttlefish and nautilus. Ammonites lived within coiled external shells divided into internal chambers. These chambers helped the animal regulate buoyancy in the water column, while the soft-bodied animal occupied the final living chamber.The species name bicarinatum refers to the strongly keeled character associated with this ammonite form. Polyplectus and related Toarcian ammonites are typically recognised for their compressed, coiled shells, ribbed ornament and sharp ventral features. Many examples show fine to moderately strong ribbing that sweeps across the whorl, creating an elegant, highly collectable Jurassic ammonite appearance.Polyplectus bicarinatum has also been recorded in palaeontological literature under related historical classifications, including Osperleioceras bicarinatum. It is associated with the ammonite order Ammonitida and the superfamily Hildoceratoidea, a group of Jurassic ammonites that includes many important forms used in biostratigraphy. Ammonites are highly useful for dating and comparing rock layers because they evolved rapidly, were abundant in ancient seas and spread widely through marine environments.Geology, Age and Toarcian SettingThis specimen is from the Lower Jurassic Toarcian Stage, a time approximately 183 to 174 million years ago. The Toarcian was an important interval in ammonite evolution, with a wide variety of elegant, ribbed and keeled ammonite forms living in warm epicontinental seas across Europe.During the Early Jurassic, the region now known as Lozère in southern France was part of a marine setting connected to wider Jurassic seas. Fine sediments accumulated on the sea floor, preserving ammonites and other marine life as fossils. Many Toarcian ammonites from France are admired for their fine detail, attractive preservation and scientific value, especially where shell form, ribbing and keel structure can be seen clearly.The Mende area in Lozère is particularly associated with Toarcian ammonites, including small, detailed and sometimes pyritised specimens from marine sedimentary deposits. Fossils from this region are popular with collectors because they combine classic Jurassic age, strong ammonite diversity and a desirable French locality.Authenticity and PresentationThis Polyplectus bicarinatum ammonite fossil is a genuine specimen and has been carefully selected for its natural character, geological interest and display appeal. It is supplied exactly as shown in the listing photograph, so the fossil pictured is the actual piece you will receive.The included Certificate of Authenticity lifetime guarantee generic card provides reassurance for collectors, educators, gift buyers and natural history enthusiasts. This makes the fossil suitable for both a serious fossil collection and an attractive display in a cabinet, study, classroom, office or geology-themed collection.Display, Collecting and Educational ValueThis Polyplectus bicarinatum ammonite is ideal for collectors of Jurassic fossils, French ammonites, Lower Jurassic cephalopods and natural history specimens. Its Toarcian age, Mende locality and distinctive ammonite morphology give it excellent appeal as both a display fossil and an educational specimen.As a genuine Lower Jurassic ammonite from Lozère, France, this fossil offers a direct connection to the ancient marine world that existed millions of years before the present day. It would make an excellent fossil gift, collector’s item, teaching specimen or display piece for anyone interested in ammonites, palaeontology, cephalopods, French geology and the fossil-rich marine deposits of the Early Jurassic.
