Description
Rare Pseudovirgatites ascrupulosus Ammonite Fossil
This listing features a rare Pseudovirgatites ascrupulosus Ammonite Fossil from the Tithonian stage of the Late Jurassic, found in Bishberg, Germany. At around 150 million years old, this ammonite represents one of the distinctive species that flourished during the final chapter of the Jurassic. Each fossil we sell is 100% genuine and comes with a Certificate of Authenticity. The exact specimen shown in the photographs is the one you will receive, with a 1 cm scale cube provided for size comparison.
Geological Context – Tithonian of Bishberg, Germany
The fossil was discovered in the Tithonian-aged deposits of Bishberg, Germany, a locality well-known for yielding important Late Jurassic ammonite faunas. During this period, the region was covered by shallow marine seas connected to the Tethys Ocean, where fine sediments of limestone and marl preserved marine organisms in exceptional detail. The Tithonian stage is the last stage of the Jurassic, just before the beginning of the Cretaceous, and ammonites from these layers provide essential data for refining global stratigraphy. Fossils from Bishberg are especially valuable because they represent a well-documented ammonite fauna used in biostratigraphic studies across Europe.
Species Overview – Pseudovirgatites ascrupulosus
The specimen belongs to Pseudovirgatites ascrupulosus, a member of the order Ammonitida, superfamily Perisphinctoidea, and family Virgatitidae. This genus is recognised for its slender, moderately involute shells and its strong, elegant ribbing. In Pseudovirgatites ascrupulosus, the ribs are typically sharp and may bifurcate across the flanks, giving the shell a finely ornamented and highly distinctive appearance.
The morphology of Pseudovirgatites suggests a nektonic lifestyle, with the animal actively swimming in open waters of the Tithonian seas. Its streamlined shape and ribbed ornamentation provided both hydrodynamic efficiency and structural reinforcement, adaptations that helped it thrive in marine ecosystems at the close of the Jurassic.
Paleontological Importance
Pseudovirgatites ascrupulosus is a key index fossil for the Tithonian stage. Its restricted stratigraphic range and distinctive morphology make it ideal for defining ammonite biozones. Paleontologists use this species to correlate Jurassic rock layers across Germany and other regions of Europe. The genus Pseudovirgatites is therefore highly significant in global Jurassic chronostratigraphy.
The fossil also illustrates the evolutionary diversification of ammonites in the Late Jurassic. Species such as Pseudovirgatites ascrupulosus show how ammonites adapted to ecological niches through shell design and ornamentation, helping them remain among the most successful marine organisms of their time.
Collector’s and Educational Value
This Pseudovirgatites ascrupulosus ammonite fossil is a rare and scientifically important specimen, perfect for collectors seeking uncommon Late Jurassic ammonites. Its finely ribbed shell and elegant form make it a visually appealing display piece, while its role in stratigraphic research ensures lasting value. It is equally suitable as a teaching specimen, providing a direct connection to the evolutionary and geological history of the Tithonian seas.
