£ 42.00
Genuine 5.5 Inch Harpoceras Ammonite Fossil from Ilminster, SomersetThis 5.5 inch Harpoceras fossil ammonite is a genuine Jurassic specimen from the
Beacon Limestone of Ilminster, Somerset, UK. It is a carefully chosen fossil with classic ammonite character, strong natural display appeal and a desirable British Jurassic locality. The photograph shows the actual specimen you will receive, so this is a unique individual fossil rather than a stock image or representative example.For full sizing and visible condition, please see the listing photo. This fossil has been selected for its attractive natural form, geological interest and suitability for display in a fossil collection, natural history cabinet, study, classroom or educational setting.Species and Scientific InterestHarpoceras is a well-known genus of Jurassic ammonite, belonging to an extinct group of marine cephalopods related to modern squid, cuttlefish and nautilus. Ammonites lived inside coiled external shells divided into a series of internal chambers. These chambers helped the animal regulate buoyancy in the water, while the living body occupied the final outer chamber.Harpoceras ammonites are especially admired for their compressed, disc-like shell form and elegant Jurassic appearance. Many specimens show curved ribs sweeping across the whorl, together with a pronounced keel around the outer edge of the shell. This keeled, streamlined form is one of the notable features that makes Harpoceras popular with fossil collectors and geology enthusiasts.The genus is part of the ammonite order Ammonitida and is associated with the superfamily Hildoceratoidea. Harpoceras and related hildoceratid ammonites are significant in Jurassic palaeontology because ammonites evolved rapidly and were widely distributed across ancient seas. This makes them useful index fossils for comparing and dating fossil-bearing rock layers.Geology, Age and LocalityThis specimen comes from the Beacon Limestone at Ilminster in Somerset, a classic British Jurassic fossil locality known for ammonites and other marine fossils. The Beacon Limestone forms part of the Jurassic rock succession of southwest England and preserves evidence of an ancient seabed environment where marine shells and organic remains accumulated over millions of years.During the Jurassic Period, the area that is now Somerset was covered by warm marine waters. These seas supported a rich ecosystem including ammonites, belemnites, bivalves, brachiopods and other marine life. When ammonites died, their shells could settle into the sediment, where they were gradually buried, mineralised and preserved within limestone and related deposits.Ilminster fossils are valued by collectors for their connection to historic British palaeontology and the fossil-rich Jurassic rocks of Somerset. A Harpoceras ammonite from this locality combines a recognisable ammonite form with a desirable UK origin, making it an appealing addition to a fossil collection.Preparation and AuthenticityYour specimen was discovered by our own team members, Alister and Alison, and has been cleaned, prepped and treated by Alison. This careful preparation helps present the fossil clearly while preserving its genuine natural character as an authentic geological specimen.This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. It is supplied exactly as shown in the listing photograph, so the fossil pictured is the actual specimen you will receive.Display, Collecting and Educational ValueThis 5.5 inch Harpoceras ammonite fossil makes an excellent display piece for fossil collectors, natural history enthusiasts, geology students and anyone interested in British Jurassic fossils. Its size gives it strong visual appeal while remaining practical for cabinet display, desk display or educational handling.As a genuine British Jurassic ammonite from Ilminster, Somerset, this specimen offers a direct link to the ancient marine world that existed long before modern Britain was formed. It would make a thoughtful fossil gift, teaching specimen or collector’s item for anyone interested in ammonites, cephalopods, British fossils, Jurassic geology and the fossil-bearing limestone deposits of southwest England.
