Description
Presenting a genuine and scientifically notable Oxycerites limosus fossil ammonite, from the Lower Bathonian Stage of the Middle Jurassic Period, collected in Sengenthal, Germany. This species is a classic representative of slender and compressed ammonites found in European Jurassic marine deposits.
Taxonomic Classification:
- Genus: Oxycerites
- Species: limosus
- Order: Ammonitida
- Superfamily: Stephanoceratoidea
- Family: Oppeliidae (sometimes classified within Perisphinctidae depending on taxonomic framework)
- Originally described in the 19th century, Oxycerites includes ammonites with narrow shells and simple ribbing, used widely in biostratigraphic studies
Geological Context:
- Stage: Lower Bathonian (Middle Jurassic)
- Age: Approx. 168 to 166 million years ago
- Locality: Sengenthal, Germany
- Formation: Jurassic marine limestones and marl facies of the Franconian Basin
- Depositional Environment: Shallow marine epicontinental sea with stable carbonate deposition, ideal for ammonite preservation
- Biozone: Typically associated with early Bathonian zones including the Procerites and Oxycerites assemblages
Morphological Features:
- Highly compressed, involute shell with a narrow profile and small umbilicus
- Smooth or weakly ribbed flanks with a sharp ventral keel
- Shell cross-section is lens-shaped or elliptical, giving the ammonite a hydrodynamic profile
- Suture lines may be visible in well-preserved specimens, showing relatively simple lobe-saddle arrangements
Scientific & Collector Importance:
- Oxycerites limosus is an index fossil in regional biostratigraphy of the Bathonian in central Europe
- Known for its elegant, streamlined form and excellent preservation in German Jurassic localities
- Sought after by fossil collectors for its rarity and sleek morphology, and by researchers for its stratigraphic utility
The fossil is photographed with a 1cm scale cube, and the exact specimen shown is the one you will receive. It has been carefully prepared to highlight key morphological details.
Authenticity Guaranteed: All fossils are 100% genuine natural specimens, accompanied by a Certificate of Authenticity. This ammonite is perfect for collectors, students, educators, and enthusiasts of Jurassic marine life.
