Fossils for Sale - High-quality BRITISH and WORLDWIDE Fossils. An impressive selection of fossils, including Ammonites, Trilobites, Belemnites, Fossil Fish, Fossil Shark Teeth, Fossilised Insects in Amber, Dinosaurs, and Reptiles. UK Fossils was formed in 1988 and collects and preps our own fossils in the heart of the Jurassic Coast, collecting fossils from Lyme Regis, Charmouth and Somerset. Our passion for fossils is reflected in our carefully curated collection, which includes some of the rarest and most unique specimens available.
This listing features a Microsphinctes mitus fossil ammonite, originating from the Oxfordian Stage of the Late Jurassic, discovered in Vienne, France. This genuine specimen is a fine example of a small but scientifically important ammonite, and it reflects both the evolutionary refinement of ammonoids and the rich paleontological heritage of southern France.
Fossil Type: Ammonite (extinct marine cephalopod)
Species: Microsphinctes mitus
Geological Period: Jurassic
Geological Stage: Oxfordian (~163.5 to 157.3 million years ago)
Provenance: Vienne, Nouvelle-Aquitaine, France
Scientific & Geological Details:
Order: Ammonitida
Superfamily: Perisphinctoidea
Family: Perisphinctidae
Morphology Features:
Typically small-sized ammonite with evolute coiling
Well-defined ribs, often simple or bifurcating
Shallow umbilicus with visible inner whorls
Biozone:
Commonly found in the upper Oxfordian ammonite zones, potentially within the Perisphinctes bifurcatus or Gregoryceras transversarium zones depending on local stratigraphy
Depositional Environment:
Formed in a shallow, warm marine shelf environment with excellent fossil preservation
Sediments consist primarily of marly limestones and fine-grained silts common to the Jurassic of southern France
Notable:
Microsphinctes mitus is valued for its finely preserved ornamentation despite its smaller size
Acts as a zonal fossil in correlation studies of Upper Jurassic strata in Western Europe
Formal Identification:
Originally described by distinguished European ammonite specialists working on Oxfordian faunas
Why This Fossil is Significant:
Authentic Oxfordian ammonite from a key Jurassic location in France
Carefully chosen for preservation quality and scientific clarity
Suitable for fossil collectors, educators, and Jurassic-era enthusiasts
Comes with full provenance and a Certificate of Authenticity
Additional Notes:

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.
