£60.00

A rare and finely preserved Parkinsonia acris Fossil Ammonite, measuring approximately 4 inches (10 cm) in diameter, from the Lower Bathonian Stage of the Jurassic Period, discovered in Calvados, Normandy, France. This striking ammonite is a classic representative of the genus and comes with a Certificate of Authenticity. The actual fossil shown in the image is the exact one you will receive.

Fossil Type & Species:

  • Type: Ammonite (extinct marine cephalopod)
  • Species: Parkinsonia acris
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Parkinsoniidae

Geological Context:

  • Period: Jurassic
  • Epoch/Stage: Middle Jurassic – Lower Bathonian (approx. 168.3 to 166.1 million years ago)
  • Biozone: Likely within the Parkinsonia acris subzone of the Parkinsonia zone (used in parts of NW Europe)
  • Depositional Environment: Shallow marine shelf with calcareous sediments – optimal for ammonite fossilisation

Locality:

  • Region: Calvados, Normandy, France
  • Formation: Bathonian marine limestones and marls of the Paris Basin (specific formation unconfirmed)

Morphology & Features:

  • Strongly ribbed evolute shell
  • High density of fine, bifurcating ribs across the flanks

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.
