RARE FOSSIL AMMONITE – Orthaspidoceras liparum – KIMMERIDGIAN STAGE – UPPER JURASSIC – LA ROCHELLE, FRANCE

This exceptional fossil specimen is a rare example of the ammonite species Orthaspidoceras liparum from the Kimmeridgian Stage of the Late Jurassic Period, found near La Rochelle, France. It represents a stunning relic of ancient marine life from approximately 157 to 152 million years ago.

This piece comes directly from the Alice Purnell Collection, renowned for its quality and curation. Every fossil we sell is 100% genuine and comes with a Certificate of Authenticity for guaranteed provenance. The photo provided shows the actual specimen for sale, and a scale cube with 1cm squares is included in the image—please refer to this for exact sizing.

GEOLOGICAL & TAXONOMIC DETAILS:

  • Species: Orthaspidoceras liparum
  • Geological Age: Late Jurassic (~157–152 Ma)
  • Stage: Kimmeridgian
  • Location: La Rochelle, Nouvelle-Aquitaine, France
  • Formation: Likely from the Upper Kimmeridgian marl-limestone successions typical of western France
  • Depositional Environment: Epicontinental marine shelf; warm, shallow, oxygen-rich seas with moderate sedimentation
  • Family: Aspidoceratidae
  • Superfamily: Perisphinctoidea
  • Order: Ammonitida
  • Class: Cephalopoda
  • Phylum: Mollusca

MORPHOLOGY & FEATURES:

Orthaspidoceras liparum is a member of the Aspidoceratid family, known for:

  • Broad, discoidal, and involute shells
  • Typically flattened flanks and wide umbilicus
  • Strong ribbing and frequent tubercles along the whorl shoulders
  • Size variability, with many specimens exceeding 10–15 cm in diameter
  • Suture patterns complex and deeply lobed

This particular specimen exhibits the classic robust ribbing and suture definition characteristic of the species.

BIOSTRATIGRAPHIC & SCIENTIFIC SIGNIFICANCE:

  • Orthaspidoceras liparum serves as a biostratigraphic marker in the Kimmeridgian of Western Europe.
  • Ammonites of this genus assist geologists in correlating marine strata across France, Germany, and the UK.
  • It is part of the diverse Aspidoceratidae family, an evolutionary offshoot noted for its ornamental shell structures and significance in Upper Jurassic ammonite biozones.

SUMMARY OF SPECIMEN:

  • Species: Orthaspidoceras liparum
  • Age: Kimmeridgian, Upper Jurassic (~157–152 Ma)
  • Formation: Likely Kimmeridgian marls/limestones
  • Locality: La Rochelle, France
  • Preservation: Excellent detail with defined ribbing and shell morphology
  • Provenance: Alice Purnell Collection
  • Authenticity: Supplied with Certificate of Authenticity
  • Photo: Shows actual specimen with 1cm scale cube

This is a rare and scientifically notable ammonite fossil, ideal for advanced collectors, educational institutions, or natural history displays. A perfect specimen with established provenance and biozone relevance.

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.
