Klematosphinctes Fossil Ammonite – Lower Oxfordian Jurassic – France – Authentic Specimen with Certificate

Original price was: £9.00.Current price is: £8.10.

This listing features a genuine Klematosphinctes fossil ammonite from the Lower Oxfordian stage of the Jurassic, discovered in France. This beautiful specimen is an excellent example of a classic perisphinctid ammonite from the early part of the Late Jurassic. Its ribbed shell and well-preserved coiling make it both scientifically valuable and visually striking.

The photo shows the exact specimen you will receive, and the scale rule/cube = 1cm gives a clear reference for full sizing.

Species & Classification:

  • Genus: Klematosphinctes
  • Type: Fossil Ammonite (Extinct Marine Cephalopod)
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea
  • Family: Perisphinctidae
  • Phylum: Mollusca
  • Class: Cephalopoda

Geological & Stratigraphic Context:

  • Period: Jurassic
  • Stage: Lower Oxfordian (approx. 163.5 – 160.3 million years ago)
  • Region: France (exact locality unspecified)
  • Depositional Environment: Shallow marine shelf with carbonate and clay-rich sedimentation; low-energy marine environment favorable to ammonite preservation
  • Biozone: Possibly within the Cardioceras cordatum Zone (based on stratigraphic occurrence of genus) – exact zone not determined for this piece

Morphological Features:

  • Typically moderately evolute to involute shell with compressed whorls
  • Prominent, bifurcating ribs radiating across the flanks
  • Rounded venter with fine keel in some specimens
  • Growth lines and suture patterns may be visible under magnification
  • Excellent for educational display and study of Jurassic ammonite morphology

Notable Information:

  • Klematosphinctes is a lesser-known but stratigraphically significant genus, often used to assist in biostratigraphic correlation of Lower Oxfordian deposits
  • It reflects evolutionary trends within the Perisphinctidae family and contributes to our understanding of faunal distribution in European marine basins during the Jurassic
  • French Oxfordian localities are classic fossil beds renowned for their ammonite diversity and exquisite preservation

Why Buy From Us?

  • 100% authentic fossil, responsibly sourced
  • Comes with a Certificate of Authenticity
  • The exact specimen shown in the photo is what you will receive
  • Ideal for collectors, educators, and geology enthusiasts

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.
