Original price was: £42.00.Current price is: £37.80.

This listing features a RARE and scientifically valuable fossil of Euryptychites latissimus, an ammonite species from the Tithonian Stage of the Late Jurassic, found in Russia. Dating to approximately 152–145 million years ago, this transitional fossil lies close to the Jurassic-Cretaceous boundary, offering exceptional geological significance.

This is a 100% genuine specimen, and you will receive the exact fossil pictured. A Certificate of Authenticity is included. Scale cube = 1cm. Please see the photo for accurate sizing.

Geological & Scientific Information:

  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Species: Euryptychites latissimus
  • Family: Perisphinctidae
  • Superfamily: Perisphinctoidea
  • Order: Ammonitida
  • Geological Stage: Tithonian, Upper Jurassic (~152–145 million years ago)
  • Location: Russia
  • Depositional Environment: Marine shelf, likely from offshore silty to clay-rich sediments in a low-energy Jurassic basin
  • Biozone Relevance: Euryptychites species are useful in the correlation of Upper Jurassic stratigraphy in Eurasia, bridging the Jurassic–Cretaceous boundary

Morphological Features:

  • Strongly ribbed, compressed shell with slightly evolute coiling
  • Wide body whorl with ornamented ribbing that may bifurcate at mid-flank
  • Typically features low keel or flattened venter and distinct suture patterns
  • Shell ornamentation is well defined and enhances visibility in prepared matrix

Scientific and Collector Significance: Euryptychites latissimus is notable for its placement within the latest Jurassic ammonite succession and for its rarity on the fossil market. The genus provides insight into ammonite diversification and paleoecology at a time of major faunal transition preceding the Early Cretaceous.

Display & Collector Value:

  • A highly collectible ammonite species rarely available from Russia
  • Stunning surface detail and rib structure make it ideal for display
  • Valuable addition for advanced collectors, educators, and museums

Why Buy from Us?

  • Every fossil is 100% genuine and responsibly sourced

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.
