Peronoceras abulatum Fossil Ammonite Jurassic Lower Toarcian Whitby UK Genuine Specimen

Description Peronoceras abulatum Fossil Ammonite from Whitby, United Kingdom This listing offers a Peronoceras abulatum fossil ammonite, an uncommon and scientifically significant specimen from the Lower Toarcian stage of the Jurassic period. Discovered in the world-famous fossil beds of Whitby, North Yorkshire, UK, this ammonite represents a key species from one of the most important Jurassic marine successions in Europe. The fossil pictured is the exact piece you will receive, with a 1 cm scale cube included for precise size reference. All of our fossils are 100% genuine and each comes with a Certificate of Authenticity. Geological Age and Setting – Lower Toarcian, Jurassic This ammonite originates from the Lower Toarcian stage, approximately 182–174 million years ago. At that time, the Whitby region was part of a shallow sea within the northern margin of the Tethys Ocean. Fine-grained mudstones and shales accumulated in this environment, forming the famous Whitby Mudstone Formation. These deposits are particularly important to palaeontology because they preserve a remarkable variety of fossils, including ammonites, belemnites, bivalves, marine reptiles, and fish. The Toarcian interval is also marked by the Toarcian Oceanic Anoxic Event (T-OAE), a time of global climate change and oceanic deoxygenation, during which many ammonite lineages—including Peronoceras—flourished. Species and Classification Genus: Peronoceras Species: abulatum Order: Ammonitida Superfamily: Hildoceratoidea Family: Hildoceratidae Peronoceras abulatum is a member of the Hildoceratidae, a family of ammonites known for their strongly ribbed, evolute shells. These ammonites are widely used as biostratigraphic markers, enabling scientists to date and correlate Jurassic deposits across Europe with precision. Morphological Features The Peronoceras abulatum ammonite is identifiable by several distinctive features: Shell form: Evolute, with earlier whorls exposed and prominent. Ribbing: Strong, radial ribs run across the flanks, often accentuated by tubercles or nodal swellings. Whorl profile: Robust and rounded, giving the fossil a powerful appearance. Ornamentation: The ribbing and tuberculation make this ammonite particularly striking, both scientifically and visually. Sutures: Complex suture patterns add further detail and are typical of Hildoceratidae ammonites. These features not only define the species but also make it highly desirable to collectors for both study and display. Stratigraphy and Biozone Importance Peronoceras abulatum is an important fossil for defining and identifying Toarcian ammonite biozones, particularly within the lower succession. Its presence is essential for refining the stratigraphy of the Whitby Mudstone Formation and contributes to the broader correlation of Jurassic strata across Europe. Collector and Scientific Value Collectors will appreciate this specimen for its rarity, distinctive ribbing, and provenance from Whitby, one of the world’s most famous Jurassic fossil sites. Researchers and educators value it as a biostratigraphic marker species that helps define Jurassic successions. For display purposes, its strong ornamentation and robust shell form make it a stunning addition to any fossil collection.
