Properisphinctes variocostatus Ammonite Fossil – Upper Oxfordian Jurassic – France – Genuine with Certificate
£9.00Original price was: £9.00.£8.10Current price is: £8.10.
This listing features a finely preserved Properisphinctes variocostatus ammonite fossil from the Upper Oxfordian Stage of the Late Jurassic, discovered in France. You will receive the exact specimen shown in the photos, with a 1cm scale cube or rule included for accurate size reference. Full measurements are available in the image gallery.
Geological and Scientific Information:
Fossil Type: Ammonite (extinct marine cephalopod)
Species:Properisphinctes variocostatus
Genus:Properisphinctes
Family: Perisphinctidae
Super Family: Perisphinctoidea
Order: Ammonitida
Geological Stage: Upper Oxfordian (Late Jurassic, approx. 158–154 million years ago)
Location: France (specific regional data not supplied)
Depositional Environment: Shallow marine environments with carbonate sedimentation and fine marl beds typical of the northern Tethyan margin
Biozone: Potentially associated with the Perisphinctes bifurcatus or Gregoryceras transversarium ammonite biozones
Morphology Features: Moderately evolute shell, well-marked radial ribbing with variable rib strength (“variocostatus”), and visible suture patterns; diagnostic of the genus
Notable Feature: The variability of ribbing makes it a key species for distinguishing Upper Oxfordian ammonite assemblages in Western Europe
Formally Identified By: Recognised and described by European palaeontologists working on Jurassic ammonite faunas in the 19th and 20th centuries, refining Perisphinctid classifications
Scientific Context:Properisphinctes variocostatus is an important ammonite species used in Upper Jurassic biostratigraphy. Known for its diverse ribbing and consistent preservation in French deposits, it aids in correlating sedimentary sequences across Western Europe. These fossils provide valuable insight into Jurassic marine biodiversity and evolutionary patterns.

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.
