Geological Setting – Black Ven Marls, Lower Lias This fossil originates from the famous Black Ven Marls, part of the Lower Lias Group, dating to the Early Jurassic approximately 190–200 million years ago. During this period, Dorset lay beneath a warm, shallow marine sea rich in ammonites, belemnites, fish, and large marine reptiles such as ichthyosaurs and plesiosaurs. The Black Ven Marls were deposited in a calm offshore environment where fine muds settled onto the seafloor. Low oxygen conditions helped preserve shells and skeletal remains before they were disturbed, allowing fossils to form with exceptional clarity. Stonebarrow Cliff and Charmouth are internationally recognised for producing some of the finest Jurassic ammonites in the world, making fossils from this locality highly sought after. Fossil Species – Caenisites Ammonite Caenisites is a distinctive ammonite genus from the Lower Jurassic, belonging to the extinct subclass Ammonoidea, within the class Cephalopoda. Ammonites were marine molluscs related to modern squid and cuttlefish, and they were among the most successful predators of Jurassic seas. Caenisites ammonites are valued for their elegant coiling, clear ribbing, and well-defined whorl structure. Like many Jurassic ammonites, Caenisites serves as an important fossil for understanding Early Jurassic marine ecosystems and for correlating strata along the Jurassic Coast. Ammonites such as this were active swimmers, using jet propulsion and buoyancy control to navigate the ancient seas of Dorset nearly 200 million years ago. Calcite Preservation and Fossil Features This specimen displays attractive calcite preservation, formed when mineral-rich fluids replaced or infilled the original shell during fossilisation. Calcite ammonites often show enhanced contrast and subtle crystalline highlights, making them especially appealing collector fossils. The ammonite retains its natural spiral geometry and shell ornamentation, preserving the unmistakable aesthetic that makes ammonites some of the most popular fossils worldwide. This fossil is ideal for display in cabinets, on desks, or within educational collections, offering a direct connection to Jurassic marine life from one of Britain’s most famous fossil sites.
