Rare Paltechioceras ebriolum Ammonite Fossil Jurassic Lyme Bay Dorset UK Genuine Authentic COA

Description Authentic Jurassic Fossil from Lyme Bay, Dorset This rare Paltechioceras ebriolum ammonite fossil is a genuine specimen from the Upper Sinemurian stage of the Early Jurassic, discovered in Lyme Bay, Dorset, United Kingdom. Carefully chosen for both its quality and scientific value, it offers a direct connection to life in the seas nearly 195 million years ago. The photographs show the actual specimen you will receive, with a 1 cm scale cube provided for accurate size reference. Each fossil is supplied with a Certificate of Authenticity, guaranteeing that it is 100% genuine. Geological Age and Provenance The fossil dates to the Upper Sinemurian stage of the Lower Jurassic, approximately 197–190 million years ago. During this time, Lyme Bay and the Dorset coast were part of shallow epicontinental seas on the margins of the Tethys Ocean. The fine mudstones and silts deposited in these environments created ideal conditions for fossil preservation. Dorset’s Lower Lias formations are world-famous for their abundance of ammonites and are a designated UNESCO World Heritage Site, forming part of the renowned Jurassic Coast. Fossils from this area are internationally important for both collectors and researchers. Species Identification and Classification Paltechioceras ebriolum belongs to the class Cephalopoda, order Ammonitida, superfamily Eoderoceratoidea, and family Echioceratidae. The genus Paltechioceras is known for its compressed shells, fine ribbing, and slender planispiral whorls. The species ebriolum occurs in ammonite-bearing horizons of the Upper Sinemurian, contributing to the subdivision of Jurassic ammonite zones. As such, it is a key fossil for paleontologists working on stratigraphy and evolutionary history within the early Jurassic seas. Morphology and Distinctive Traits This specimen displays the diagnostic features of Paltechioceras ebriolum, including compressed, tightly coiled whorls with delicate ribbing. The ribs are fine, evenly spaced, and sweep symmetrically across the flanks of the shell, producing an elegant ornamentation. These traits would have reinforced the shell’s structure while also aiding hydrodynamics in the water column. The refined ornamentation makes this species highly recognisable and desirable to collectors, with its aesthetic qualities complementing its scientific significance. Scientific and Stratigraphic Importance Paltechioceras ebriolum is scientifically significant as part of the Upper Sinemurian ammonite assemblages that define internationally recognised biozones. Ammonites of this genus and species are used as index fossils, enabling precise dating and correlation of strata across Europe. This makes them central to the construction of the Jurassic timescale and the reconstruction of ancient marine ecosystems. Collectors value specimens of ebriolum not only for their beauty but also for their role in documenting one of the most important periods of ammonite diversification. Condition and Presentation This fossil has been professionally prepared to preserve its natural integrity while highlighting the features that make it distinct. The ribbing, shell curvature, and whorl development are clearly visible, making it both an attractive and scientifically valuable specimen. It is a one-of-a-kind fossil, not a cast or replica.
