Binatisphinctes Ammonite Fossil Jurassic Switzerland Genuine COA Card Specimen - Callovian Middle Jurassic Collector Display
£ 48.00
Binatisphinctes sp. Ammonite Fossil from SwitzerlandThis is a genuine Binatisphinctes sp. ammonite fossil from the Middle Jurassic,
Callovian stage, collected from Switzerland. This carefully chosen fossil is an attractive European Jurassic marine cephalopod specimen, selected for its natural form, geological interest, and collectable display appeal. It is supplied with a Certificate of Authenticity lifetime guarantee generic card, making it a trusted addition to an ammonite collection, fossil cabinet, educational geology display, natural history collection, or prehistoric gift selection.The photograph shows the actual fossil specimen you will receive. Full sizing and scale can be seen in the photo.Geological Age and LocationThis ammonite dates to the Callovian stage of the Middle Jurassic, approximately 166 to 163 million years old. The Callovian was an important period in ammonite evolution, with many diverse and highly ornamented ammonite groups spreading through the warm marine seas of Europe. Ammonites from this stage are especially valued by collectors and geologists because their distinctive shell forms help date and correlate Jurassic rock layers.During the Middle Jurassic, parts of what is now Switzerland were covered by shallow to moderately deep marine environments linked to the wider European seaways and the ancient Tethys Ocean. These seas deposited limestones, marls, clays, and shell-rich sediments that preserved a wide range of marine fossils, including ammonites, belemnites, bivalves, brachiopods, gastropods, echinoids, crinoids, fish remains, and other prehistoric sea life.Fossil Type and IdentificationThis fossil is identified as Binatisphinctes sp., an extinct ammonite from the Middle Jurassic. The “sp.” designation means the specimen has been identified to genus level, while the exact species is left open. This is commonly used where preservation, natural variation, or visible diagnostic details make a precise species-level identification unsuitable.Binatisphinctes belongs to the perisphinctid ammonite group, a major Jurassic ammonite lineage known for evolute coiled shells and strong ribbing. Perisphinctid ammonites are among the most recognisable Jurassic ammonites and are widely collected for their attractive spiral form, detailed ornament, and importance in biostratigraphy.Ammonites were extinct marine molluscs related to modern squid, cuttlefish, octopus, and nautilus. They had hard external shells divided internally into chambers. The living animal occupied the outer body chamber, while earlier chambers helped regulate buoyancy, allowing the ammonite to move through the water column.Morphology and Notable FeaturesBinatisphinctes ammonites are appreciated for their classic Jurassic appearance, often showing an evolute shell with visible inner whorls and a defined central umbilicus. The whorls are typically arranged in a balanced spiral, creating the iconic ammonite shape that makes these fossils so popular with collectors.Perisphinctid-style ammonites commonly display strong ribbing across the flanks of the shell. These ribs may divide, curve, or continue across the outer edge of the shell, depending on the growth stage and preservation of the specimen. This ornament gives the fossil depth, texture, and visual interest, while also reflecting the growth of the animal during life.The shell was divided into chambers by internal walls called septa. Where these septa met the shell surface, they formed suture lines, which are important in ammonite classification. Even when sutures are not fully visible, the shell shape, whorl proportions, ribbing, and overall structure preserve valuable evidence of the ammonite’s biology and Jurassic marine environment.As a genuine fossil, this specimen may show natural matrix, mineralisation, fossil shell texture, colour variation, weathering, small chips, cracks, or areas of natural wear caused by fossilisation and geological history. These features are normal for authentic fossils and add to the individuality of the piece. The photo shows the exact specimen being offered, allowing the buyer to view its preservation, condition, size, and display quality before purchase.Middle Jurassic Marine EnvironmentThis Binatisphinctes ammonite lived in the warm marine waters that covered parts of Switzerland during the Callovian. These ancient seas supported a rich ecosystem of swimming cephalopods, fish, and seabed-dwelling invertebrates. Ammonites were active swimming or drifting animals, likely feeding on small prey in the water column using tentacles.After death, the ammonite shell could settle onto the seabed and become buried by sediment. Over millions of years, mineralisation, compaction, and geological change transformed the shell and surrounding sediment into fossil-bearing rock. This fossil is a direct link to the Middle Jurassic seas of Europe, when dinosaurs lived on land and ammonites flourished in the oceans.Authenticity and CollectabilityThis Binatisphinctes sp. ammonite fossil is a genuine specimen from Switzerland, dating to the Callovian stage of the Middle Jurassic, and includes a Certificate of Authenticity lifetime guarantee generic card. It is suitable for collectors of Jurassic ammonites, Swiss fossils, Middle Jurassic marine fossils, European fossils, natural history specimens, educational geology pieces, and display fossils.This carefully selected fossil includes a Certificate of Authenticity lifetime guarantee generic card, and the fossil shown in the photo is the actual specimen you will receive.
