Rare Fossil Ammonite Properisphinctes bernensis Jurassic Callovian Plettenberg Germany | Authentic Fossil

£36.00

This listing features a rare and scientifically significant fossil of Properisphinctes bernensis, an elegant ammonite species from the Callovian stage of the Middle Jurassic period. This beautifully preserved specimen was found in the well-known marine sedimentary layers near Plettenberg, Germany, a classic locality for Jurassic marine fossils.

Geological Context:

  • Fossil Type: Ammonite (Extinct marine mollusc, relative of squid and octopus)
  • Species: Properisphinctes bernensis (Salfeld, 1913)
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea
  • Family: Perisphinctidae
  • Geological Stage: Callovian (c. 166.1 to 161.2 million years ago)
  • Formation: Marine marl and limestone beds of the Swabian Jura
  • Depositional Environment: Shallow marine shelf with carbonate and marl sedimentation

Properisphinctes is a genus known for its gracefully ribbed, evolute shells, and P. bernensis is particularly valued for its stratigraphic importance and aesthetic symmetry. It is a key biostratigraphic species for correlating Callovian sequences across Central Europe.

Morphology & Notable Features:

  • Evolute shell with exposed inner whorls
  • Fine, bifurcating ribs that curve gently across the flanks
  • Rounded to slightly angular venter with no keel
  • Moderate umbilicus and compressed cross-section
  • Typical Perisphinctid suture patterns

Biozone Association: Properisphinctes bernensis is associated with the Bernensis Biohorizon of the Middle Callovian, particularly relevant to German and Swiss Jurassic stratigraphy. It provides key data for ammonite-based zonation schemes.

Specimen Details:

  • Origin: Plettenberg, Baden-Württemberg, Germany
  • Age: Callovian Stage, Middle Jurassic (~163 million years old)
  • Scale: Scale rule square/cube = 1cm. Please refer to the photo for exact size
  • Condition: Selected for completeness and preservation
  • Photo: The fossil shown is the exact specimen you will receive

Certification & Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity. We carefully choose each piece for its scientific integrity, collector value, and natural beauty.

This rare Properisphinctes bernensis ammonite from the classic Jurassic strata of Germany is a collector-grade fossil, ideal for enthusiasts, educators, and palaeontologists seeking high-quality and regionally significant specimens.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
