RARE Erymnoceras coronatus Ammonite Fossil | Callovian Jurassic | Russia | Genuine Specimen w/ COA

Original price was: £120.00.Current price is: £108.00.

This listing features a RARE and well-preserved specimen of Erymnoceras coronatus, a distinctive ammonite from the Callovian stage of the Middle Jurassic, sourced from classic fossil-bearing strata in Russia. This genus is notable for its striking ornamentation and coiling, making it a favourite among collectors and paleontologists.

You will receive the exact fossil shown in the photo, with a 1cm cube scale included for size reference—please refer to the image for full measurements. As always, this is a 100% genuine fossil, carefully selected and provided with a Certificate of Authenticity.

Geological & Scientific Information:

  • Species: Erymnoceras coronatus
  • Type: Fossil Ammonite (extinct marine cephalopod)
  • Geological Period: Jurassic
  • Stage: Callovian (approx. 166–163 million years ago)
  • Location Found: Russia
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Stephanoceratidae
  • Morphological Features: Erymnoceras is recognised by its robust, involute shell with prominent ribbing and characteristic coronate tubercles (nodes or spines along the whorl). The suture lines are complex and deeply lobed. This specimen displays the genus’s signature spiny appearance and dense ribbing, typical of mid-Callovian ammonite fauna.
  • Depositional Environment: Shallow marine shelf environment composed of marl and limestone, indicative of calm to moderately dynamic seafloor conditions. These conditions were optimal for the fossilisation of ammonite shells in fine-grained sediments.
  • Scientific Importance: Erymnoceras is biostratigraphically important and often used in regional correlation within the Callovian of Europe and Asia. Its ornate features also reflect evolutionary responses to predation and environmental changes during the Middle Jurassic.

Additional Notes:

Specimens like this are prized not only for their scientific value but also for their aesthetic appeal. Erymnoceras coronatus is a hallmark species for Callovian ammonite collections and makes a standout display piece.

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.
