It is supplied with a Certificate of Authenticity lifetime guarantee generic card, confirming that this is a genuine fossil specimen and making it ideal for collectors, natural history displays, educational use and Jurassic fossil enthusiasts. ABOUT HILDOCERAS SUBPLANATUMHildoceras subplanatum is an extinct ammonite species from the Jurassic seas. Ammonites were marine cephalopods, related to modern squid, octopus and nautilus, but they lived inside a coiled, chambered shell. The living animal occupied the final outer chamber, while the earlier chambers helped control buoyancy as it moved through the water.Hildoceras is one of the most recognisable ammonite genera of the Lower Jurassic and is especially associated with the Toarcian Stage. This genus belongs to the family Hildoceratidae, within the superfamily Hildoceratoidea and the order Ammonitida. Hildoceras ammonites are highly valued by collectors and geologists because they are attractive, distinctive and important for understanding Jurassic rock sequences. SHELL FORM AND MORPHOLOGYHildoceras ammonites are known for their elegant planispiral coiling, clear whorl structure and attractive ribbed ornament. The shell is typically compressed in form, with curved ribs that sweep across the flanks and a recognisable outer edge. Many Hildoceras species display a lateral groove or sulcus along the whorl, helping to give the shell its distinctive appearance.Hildoceras subplanatum is particularly appealing as a display fossil because of its classic ammonite shape and scientific interest. The species name suggests a comparatively flattened or gently planed shell form, a feature that fits well with the compressed profile seen in many hildoceratid ammonites. These details make Hildoceras specimens excellent examples for anyone interested in ammonite anatomy, Jurassic marine life and fossil shell ornamentation. GEOLOGICAL AGE AND BEACON LIMESTONEThis specimen comes from the Beacon Limestone, a fossiliferous Jurassic limestone unit known from the Ilminster area of Somerset. The Beacon Limestone is well regarded for producing British Jurassic ammonites and other marine fossils preserved within hard limestone beds.Hildoceras is associated with the Lower Jurassic Toarcian Stage, a time around 182 to 174 million years ago when much of southern Britain lay beneath warm marine waters. Ammonites from this interval are important index fossils because they evolved rapidly and were widely distributed across ancient seas. Their presence allows geologists to date and correlate Jurassic rock layers with great precision. ILMINSTER, SOMERSET FOSSIL LOCALITYIlminster, Somerset is a classic British Jurassic fossil locality, known for ammonites and other marine fossils from the surrounding limestone beds. During the Jurassic Period, this region formed part of a shallow marine environment where carbonate-rich sediments accumulated on the seabed.The ancient sea supported a diverse ecosystem of ammonites, belemnites, bivalves, brachiopods, fish and marine reptiles. When ammonites died, their shells could settle onto the seabed, become buried by sediment and, over millions of years, fossilise within the limestone. Fossils from Ilminster are valued for their historic British provenance and their connection to the famous Jurassic geology of southwest England. COLLECTABLE BRITISH JURASSIC DISPLAY FOSSILThis Hildoceras subplanatum ammonite fossil is a desirable specimen for collectors of British fossils, Jurassic ammonites, Somerset fossils, natural history items and educational geological material. Its recognised genus, Beacon Limestone origin and classic Ilminster locality make it an excellent addition to a fossil collection, display cabinet or teaching set.The specimen has been carefully selected for its natural character and display appeal. As the photograph shows the exact fossil supplied, you can buy with confidence knowing precisely which piece will be received. With its genuine Jurassic age, British provenance and included Certificate of Authenticity lifetime guarantee generic card, this Hildoceras subplanatum fossil offers a direct connection to the ancient seas of Jurassic Somerset.
