RARE Subkossmatia opis Fossil Ammonite – Middle Jurassic Callovian – Bourges France – Genuine with COA – Collector Specimen

Original price was: £31.20.Current price is: £26.40.

Available here is a rare and scientifically notable specimen of Subkossmatia opis, a fossil ammonite from the Middle Callovian stage of the Jurassic period, collected in the region of Bourges, France. This beautifully preserved ammonite comes from marine strata deposited in the western Tethys seaway, a prolific region for Jurassic marine fossils.

Subkossmatia opis is a distinctive member of the family Reineckeiidae, often identified by:

  • Evolute coiling with all whorls visible
  • Broad, strong primary ribs that bifurcate mid-flank
  • A rounded to sub-quadrate cross-section and ventral keel
  • Species: Subkossmatia opis
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea
  • Family: Reineckeiidae
  • Geological Stage: Middle Callovian, Middle Jurassic
  • Location: Bourges, France
  • Depositional Environment: Shallow marine carbonate platform, western Tethyan shelf
  • Biozone: Likely within the Reineckeiidae-bearing upper Callovian zones (e.g., Eucyclum Subzone)

This specimen dates to approximately 165 million years ago, a period marked by diversification and radiation of marine ammonoids. Fossils of Subkossmatia opis are uncommon, making this a particularly valuable item for collectors, museums, or educational displays.

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.
