The photographs show the exact fossil you will receive, with a 1 cm scale cube provided for accurate size reference. Every fossil we offer is 100% authentic and comes with a Certificate of Authenticity. Geological Setting – Lower Pliensbachian, Jurassic The specimen dates to the Lower Pliensbachian stage, approximately 190–183 million years ago. At this time, the Yorkshire coast lay beneath shallow seas that deposited fine mudstones and shales, forming the famous Whitby Mudstone Formation. These sediments preserved ammonites, belemnites, and marine reptiles in exceptional detail, making Whitby one of the most important Jurassic fossil localities in the world. The Lower Pliensbachian represents a significant interval in Jurassic time, marked by diversification in ammonite lineages and changes in marine ecosystems. Fossils from this period are key to understanding both palaeontological and geological developments. Species and Taxonomy Genus: Coeloderoceras Species: pruticum Order: Ammonitida Superfamily: Eoderoceratoidea Family: Dactylioceratidae Coeloderoceras pruticum is part of the Dactylioceratidae, a family of ammonites that flourished during the Early Jurassic. This genus is particularly important in biostratigraphy, as its fossils define specific intervals of the Lower Pliensbachian and are used as index species in correlation studies. Morphological Features The Coeloderoceras pruticum ammonite is recognised by several distinctive characteristics: Shell form: Involute with thick, rounded whorls. Ribbing: Bold, strong ribs that bifurcate toward the venter, giving the shell a strikingly ornate appearance. Whorl profile: Deeply rounded with well-developed ornamentation. Ornamentation: Ribbing and suture patterns that add both scientific and aesthetic appeal. These features not only define its taxonomic identity but also make it a visually impressive fossil, ideal for display and study. Stratigraphic and Biozone Importance Coeloderoceras pruticum is associated with the Coeloderoceras Biozone of the Lower Pliensbachian. Its presence in Whitby’s famous mudstones provides a reliable stratigraphic marker, allowing geologists to correlate Jurassic rock layers across Europe. This makes it highly valuable for scientific research as well as fossil collections. Collector and Scientific Significance This specimen appeals to multiple audiences: Collectors appreciate its rarity, bold ribbing, and historic provenance from Whitby. Researchers and educators value it as a stratigraphic marker species and teaching example of Early Jurassic ammonites. Display collections benefit from its ornate ribbing and strong presence, making it a centrepiece in any fossil showcase.
