£ 60.00
Genuine 6.5 Inch Harpoceras Ammonite Fossil from Ilminster, SomersetThis 6.5 inch Harpoceras fossil ammonite is a genuine Jurassic specimen from the
Beacon Limestone of Ilminster, Somerset, UK. It is a carefully chosen fossil with excellent natural character, strong display appeal and classic British Jurassic interest. The photograph shows the actual specimen you will receive, making this 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 collectors, natural history enthusiasts and anyone looking for an authentic ammonite from one of Somerset’s well-known Jurassic fossil localities.Species and Scientific InterestHarpoceras is a distinctive genus of ammonite, an extinct group of marine cephalopods related to modern squid, cuttlefish and nautilus. Unlike squid, ammonites lived inside a coiled external shell divided into internal chambers. These chambers allowed the animal to control buoyancy while the living body occupied the final outer chamber.Harpoceras ammonites are particularly recognisable for their compressed, disc-like shell shape, often with a pronounced keel running around the outer edge of the whorl. Many examples show elegant curved ribbing that sweeps across the shell towards the ventral margin. This streamlined shell form is one of the features that makes Harpoceras popular with fossil collectors, as it gives the ammonite a very classic Jurassic appearance.Harpoceras belongs to the ammonite order Ammonitida and is associated with the superfamily Hildoceratoidea. Members of this group are important in Jurassic biostratigraphy because ammonites evolved rapidly and were widely distributed in ancient seas, making them useful fossils for comparing and dating rock layers.Geology, Age and LocalityThis specimen comes from the Beacon Limestone at Ilminster in Somerset, a historic Jurassic fossil-bearing deposit known for ammonites and other marine fossils. The Beacon Limestone is generally associated with the Lower Jurassic to early Middle Jurassic succession of southwest England, depending on the local bed and exposure.During the Jurassic Period, the area that is now Somerset was covered by warm marine waters. Sediments accumulated on the ancient sea floor, preserving the remains of ammonites, bivalves, belemnites and other marine life. Over millions of years, these remains became fossilised within limestone and related deposits, creating the fossil-rich beds now collected and studied by geologists and palaeontologists.Ilminster fossils are valued for their link to Britain’s classic Jurassic geology. A Harpoceras from this locality is especially appealing because it combines an attractive ammonite form with a well-regarded British fossil location.Preparation and AuthenticityYour specimen was discovered by our own team members, Alister and Alison, and has been cleaned, prepped and treated by Alison. This preparation helps reveal the fossil’s natural form while preserving its genuine 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 piece pictured is the actual fossil you will receive.Display, Collecting and Educational ValueThis 6.5 inch Harpoceras ammonite makes an excellent display fossil for a cabinet, study, office, classroom, geology collection or natural history display. Its size, classic coiled ammonite shape and Somerset Jurassic origin make it suitable for both experienced collectors and those beginning a fossil collection.As a genuine British Jurassic ammonite from Ilminster, Somerset, this specimen offers a direct connection to an ancient marine world that existed millions of years ago. It would make a thoughtful natural history gift, educational specimen or collector’s item for anyone interested in ammonites, cephalopods, British fossils, Jurassic geology and the fossil-rich limestone deposits of southwest England.
