Carefully chosen for its scientific value and aesthetic appeal, it represents a rare and fascinating example of Jurassic marine life. The photographs show the exact specimen you will receive, with a 1 cm scale cube included for accurate measurement. Every fossil is accompanied by a Certificate of Authenticity, confirming it is 100% genuine.

Geological Age and Origin

Dating back around 166–163 million years, this ammonite was formed during the Lower Callovian stage of the Jurassic Period. At that time, the area that is now the Kursk region of Russia was submerged beneath shallow seas connected to the wider Tethys Ocean. These warm marine environments provided the perfect conditions for the flourishing of ammonites and other cephalopods. The fine-grained sediments of the Kursk Iron Ore Basin helped preserve these marine creatures in excellent detail, leaving behind spectacular fossils that continue to captivate scientists and collectors alike.

Species Identification and Classification

Kepperlerites vardekloftiensis is classified within the class Cephalopoda, order Ammonitida, superfamily Stephanoceratoidea, and family Cardioceratidae. Ammonites of this genus are distinctive Callovian fossils, often noted for their ribbing patterns and compressed shell form. The species vardekloftiensis plays an important role in Callovian stratigraphy, helping to define biostratigraphic zones that allow geologists to date and correlate Jurassic rock layers with precision across vast regions of Europe and Russia.

Morphology and Key Features

This specimen displays the defining characteristics of Kepperlerites vardekloftiensis. Its shell is planispiral, meaning it coils in a flat spiral, with compressed whorls and strong ribbing. The ribs are typically regular and radiate across the flanks, converging towards the outer shell edge in a rhythmic pattern. This structural design not only reinforced the shell but also enhanced its hydrodynamic properties, allowing the ammonite to navigate effectively in Jurassic seas. The bold ribbing and symmetry give the fossil both scientific importance and visual appeal.

Scientific and Stratigraphic Value

Ammonites like Kepperlerites vardekloftiensis are invaluable index fossils. Their relatively short stratigraphic range, distinct features, and wide distribution make them essential for subdividing the Callovian stage into finer biozones. These fossils provide critical data for reconstructing Jurassic paleoenvironments, cephalopod evolution, and global marine correlations. For collectors, owning a specimen like this is not only about its aesthetic beauty but also about holding a piece of geological history that has directly contributed to our understanding of Earth’s deep past.

Condition and Presentation
