Whitbyceras Fossil Ammonite – Upper Toarcian, Whitby Jurassic CoastThis impressive fossil ammonite from the genus Whitbyceras originates from the
world-famous Upper Toarcian deposits of Whitby, North Yorkshire, United Kingdom. Dating to approximately 180 million years ago during the Early Jurassic period, this specimen represents a classic example of marine life from one of the most significant fossil-bearing regions in Europe.Discovered by our dedicated team members, Alister and Alison, this ammonite has been carefully cleaned, expertly prepared, and treated by Alison to enhance its natural structure while preserving its authenticity. The fossil shown in the photographs is the exact specimen you will receive, making it a unique and highly collectible piece.Geological Context and StratigraphyWhitby’s Jurassic coastline is renowned for its Lias Group sediments, particularly the fossil-rich shales and mudstones of the Upper Toarcian stage. These deposits were formed in a relatively deep marine basin where fine sediments accumulated slowly under calm conditions.During this time, periodic low-oxygen events on the sea floor contributed to exceptional fossil preservation, allowing delicate shell structures to survive intact. Ammonites such as Whitbyceras are commonly associated with these strata and are important for identifying specific horizons within the Jurassic sequence.Taxonomy and Scientific ClassificationWhitbyceras belongs to the order Ammonitida, an extinct group of marine cephalopods closely related to modern squid and octopus. These animals were highly successful predators in Jurassic seas and are known for their coiled, chambered shells used for buoyancy control.This genus is associated with the superfamily Hildoceratoidea, a group characterised by streamlined shells and evolutionary significance during the Early Jurassic. Ammonites within this group are widely used as index fossils due to their rapid evolution and broad distribution.Morphology and Shell FeaturesThis specimen displays the classic planispiral coiling typical of ammonites, with well-defined whorls and a balanced, symmetrical form. The shell may exhibit fine ribbing or subtle ornamentation, depending on the specific growth stage and preservation.The whorl section is generally compressed, and a keel may be present along the outer margin, contributing to efficient movement through the water. Growth lines can often be observed across the surface, providing insight into the gradual development of the shell during the organism’s life.The natural mineralisation enhances the fossil’s visual appeal, highlighting its structural features and giving it a striking appearance suitable for display.Depositional Environment and PreservationDuring the Toarcian stage, the Whitby region was submerged beneath a marine basin where fine-grained sediments settled over time. These calm depositional conditions, combined with low oxygen levels, created an ideal environment for preserving marine fossils in remarkable detail.Alison’s careful preparation has revealed the ammonite clearly while maintaining elements of the surrounding matrix for context. This approach ensures that the fossil retains its natural character and geological authenticity.Full sizing details can be confirmed via the accompanying photographs.Authenticity and ProvenanceThis fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee card, ensuring complete confidence in its origin and identification. Each specimen is responsibly sourced and handled directly by our team, providing full traceability from discovery through to final preparation.Collector Appeal and Display ValueWhitby ammonites are among the most sought-after fossils in the world, valued for their preservation, historical importance, and aesthetic appeal. This Whitbyceras specimen is an excellent example, combining elegant form with strong visual presence.Ideal for collectors of Jurassic fossils, ammonites, or British geological specimens, this piece offers both scientific interest and display quality. Whether showcased in a cabinet, study, or gallery, it provides a direct connection to the ancient seas that once covered the United Kingdom.
