£ 8.40
GENUINE PROMICROCERAS CALCITE AMMONITE NODULEThis listing is for a genuine Promicroceras calcite ammonite nodule from the
Black Ven Marls, Lower Lias, collected from the Jurassic Coast at Charmouth, Lyme Regis, Dorset, UK. This is a carefully chosen fossil specimen with excellent British Jurassic provenance, selected for its natural character, collectable appeal and attractive calcite preservation.The photograph shows the actual specimen you will receive, allowing you to view the ammonite, nodule, preservation and natural display form before purchase. Full sizing and scale details can be seen in the photo. Your specimen was discovered by our own team members, Alister and Alison, and has been carefully cleaned, prepped and treated by Alison. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming that this is a genuine fossil specimen suitable for collectors, educational displays, natural history cabinets and geology gifts. ABOUT PROMICROCERAS AMMONITESPromicroceras is an extinct genus of ammonite from the Early Jurassic seas. Ammonites were marine cephalopods, related to modern squid, octopus and nautilus, but unlike squid and octopus they lived inside a coiled, chambered shell. The living animal occupied the final outer chamber, while earlier chambers helped regulate buoyancy as it moved through the ancient marine environment.Promicroceras is especially associated with the Lower Jurassic, including the Sinemurian Stage, and is well known from classic fossil localities along the Dorset coast. The genus belongs to the family Eoderoceratidae, within the superfamily Eoderoceratoidea and the order Ammonitida. Promicroceras ammonites are popular with collectors because they are often compact, attractive, well-shaped fossils with distinctive ribbing and classic Jurassic character. CALCITE PRESERVATION AND NODULE FEATURESThis specimen is described as a calcite ammonite nodule, meaning the ammonite is preserved within a natural nodule with calcite mineralisation. Calcite preservation can give Jurassic ammonites an attractive crystalline or pale mineral appearance, enhancing both their display quality and geological interest. Nodules are especially desirable because they preserve the fossil within the rock in which it formed, offering a natural connection to the original Jurassic seabed.Promicroceras ammonites typically show a planispiral coiled shell with rounded whorls and regular ribbing. Their compact form makes them highly appealing for fossil cabinets, study collections and display pieces. The chambered shell structure, original coiling and preserved ornamentation give a direct glimpse into the anatomy of an ammonite that lived in the seas of Dorset millions of years ago. BLACK VEN MARLS AND LOWER LIAS GEOLOGYThis fossil comes from the Black Ven Marls, part of the Lower Lias sequence exposed between Charmouth and Lyme Regis. These deposits are famous for producing a wide variety of Lower Jurassic fossils, including ammonites, belemnites, bivalves, fish remains and marine reptile material.The Black Ven Marls represent an ancient marine depositional environment where fine muds and sediments accumulated on the seabed. Over time, shells and other remains became buried, mineralised and preserved as fossils. Ammonite nodules from these beds are particularly collectable because they combine natural matrix preservation with the scientific interest of one of Britain’s most famous fossil-bearing formations. CHARMOUTH, LYME REGIS AND THE JURASSIC COASTCharmouth and Lyme Regis, Dorset are among the most famous fossil localities in the United Kingdom. This coastline forms part of the Jurassic Coast, a UNESCO World Heritage Site internationally recognised for its exceptional geological record. The cliffs around Black Ven have been studied and collected for generations, producing fossils that help tell the story of ancient marine life from the Early Jurassic.A Promicroceras ammonite from this locality is especially appealing because it carries classic Dorset provenance, strong display value and a direct connection to one of the world’s best-known fossil coastlines. COLLECTABLE BRITISH JURASSIC DISPLAY FOSSILThis Promicroceras calcite ammonite nodule from Charmouth and Lyme Regis is a desirable specimen for collectors of British fossils, Jurassic Coast fossils, Dorset ammonites, Lower Lias specimens, ammonite nodules and natural history display pieces. Its origin from the Black Ven Marls gives it excellent geological context and strong collectable appeal.The specimen has been carefully selected for authenticity, natural appearance and display interest. With its genuine Jurassic age, classic UK locality, actual-specimen photograph and included Certificate of Authenticity lifetime guarantee generic card, this Promicroceras calcite ammonite nodule offers a direct connection to the ancient marine world of Jurassic Dorset.
