£ 24.00
DACTYLIOCERAS COMMUNE FOSSIL AMMONITE FROM WHITBY, YORKSHIREThis listing features a well-preserved Dactylioceras commune fossil ammonite
from the world-famous Whitby locality in Yorkshire, United Kingdom. Dating to the Lower Toarcian stage of the Jurassic period, this specimen is a striking example of one of the most iconic ammonites of Britain. Every fossil we offer is a genuine specimen, carefully selected and individually photographed so you know exactly which piece you are buying. A 1 cm scale cube is shown in the photographs for accurate sizing. All our fossils are accompanied by a Certificate of Authenticity for your assurance. GEOLOGICAL AGE AND LOCALITY – LOWER TOARCIAN, JURASSICThe fossil originates from the Lower Toarcian stage of the Early Jurassic, approximately 182–174 million years ago. During this time, Whitby and the surrounding Yorkshire coast were submerged beneath warm epicontinental seas. These seas deposited rich black shales and fine sediments, which preserved marine life in extraordinary detail. The Whitby area is world-renowned for its ammonites, and Dactylioceras commune is one of the most abundant and scientifically important species from this region. Fossils from this site are highly sought after for their preservation, beauty, and scientific value. TAXONOMY AND CLASSIFICATION
• Genus: Dactylioceras
• Species: commune
• Order: Ammonitida
• Superfamily: Hildoceratoidea
• Family: DactylioceratidaeDactylioceras commune is one of the most recognisable members of the Dactylioceratidae, a family known for its tightly coiled shells and fine ribbing. These ammonites are widely used as biostratigraphic markers for the Lower Toarcian, making them essential in geological studies. MORPHOLOGICAL FEATURESThis ammonite species exhibits several defining characteristics:
• Shell coiling: Strongly involute, with inner whorls often obscured.
• Ribbing: Numerous fine ribs extend across the shell, curving elegantly toward the aperture.
• Whorl shape: Relatively compressed with a narrow venter, contributing to its hydrodynamic form.
• Ornamentation: The regular ribbing and symmetry create a visually striking fossil, highly prized by collectors.These features not only make Dactylioceras commune instantly recognisable but also provide insight into its evolutionary adaptations and role in Jurassic marine ecosystems. STRATIGRAPHIC AND BIOZONE IMPORTANCEDactylioceras commune is widely distributed and serves as a key index fossil for the Lower Toarcian. Its presence is strongly associated with the Dactylioceras commune Zone, a subdivision of the Toarcian stage. This makes it a fossil of great importance for correlating sedimentary layers across Europe and beyond. The abundance and clarity of preservation in Whitby specimens have made this species a cornerstone of Jurassic palaeontology. SCIENTIFIC AND COLLECTOR VALUEThis ammonite holds value both as a collector’s specimen and a scientific reference fossil:
• For collectors, it offers a classic Whitby ammonite, well-preserved and display-ready.
• For researchers and educators, it provides a clear example of an important stratigraphic marker species.
• For display, its elegant ribbing and natural form make it an attractive piece of natural history. AUTHENTICITY AND GUARANTEEAs with all our fossils, this Dactylioceras commune ammonite is 100% genuine and responsibly sourced. It has been carefully cleaned and prepared to highlight its natural features while maintaining authenticity. Every purchase includes a Certificate of Authenticity, ensuring confidence in its provenance. KEY INFORMATION AT A GLANCE
