Original price was: £14.40.Current price is: £12.96.

This listing is for an authentic Perisphinctes pickeringius fossil ammonite, preserved in Ampthill Clay from the Oxfordian Stage of the Upper Jurassic, discovered at Portland, Dorset, United Kingdom. This is a classic example of a finely ribbed Perisphinctes ammonite, known for its elegant morphology and importance in Jurassic biostratigraphy.

The photo shows the actual specimen you will receive, and the scale cube = 1cm provides accurate sizing. Please refer to the image for full dimensions and detail.

Species & Classification:

  • Species: Perisphinctes pickeringius
  • Type: Fossil Ammonite (extinct marine cephalopod)
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea

  • Phylum: Mollusca
  • Class: Cephalopoda

Geological & Stratigraphic Context:

  • Period: Jurassic
  • Epoch: Late Jurassic
  • Stage: Oxfordian (~163.5 – 157.3 million years ago)
  • Formation: Ampthill Clay Formation
  • Locality: Portland, Dorset, England, UK
  • Depositional Environment: Shallow marine shelf – low-energy clay-rich seafloor with episodic sediment influx, ideal for fossil preservation

Morphological Features:

  • Planispiral shell with strongly ribbed, finely detailed ornamentation
  • Moderately involute coiling with a visible umbilicus
  • Ribs are bifurcating or trifurcating from nodes on the flank and cross over the venter

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.
