Perisphinctes Fossil Ammonite – Oxfordian Jurassic – Poland (Niegowonice/Ogndzemiec) – Genuine Fossil with COA

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

This listing features a genuine Perisphinctes fossil ammonite from the Oxfordian Stage of the Late Jurassic, collected from the classic fossil-rich localities of Niegowonice/Ogndzemiec, Poland. Ammonites of this genus are renowned for their beautifully ribbed spiral shells, which served as buoyant chambers for life in Jurassic seas.

The specimen shown in the photo is the exact fossil you will receive, and the scale rule = 1cm per square/cube. Please see the image for complete sizing and detail.

Species & Classification:

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

Geological & Stratigraphic Context:

  • Period: Jurassic
  • Stage: Oxfordian (approx. 163.5 – 157.3 million years ago)
  • Formation: Possibly the Plicatilis or Transversarium Zone (based on locality, though exact zone depends on precise bed)
  • Locality: Niegowonice/Ogndzemiec, Poland
  • Depositional Environment: Warm shallow marine shelf with carbonate sedimentation, ideal for nektonic ammonites
  • Preservation: Typically calcitic shell preserved within fine-grained limestone or marly layers

Morphological Features:

  • Planispiral shell, generally compressed with fine radial ribbing
  • Ribs may bifurcate or trifurcate at mid-flank, typical of Oxfordian Perisphinctes
  • Umbilicus is moderately wide, exposing inner whorls
  • Sutural complexity reflects evolutionary advancement in buoyancy control

Notable Information:

  • Ammonites such as Perisphinctes are valuable biostratigraphic markers for Jurassic marine sediments
  • Oxfordian Perisphinctes species are especially common across Europe, including England, France, Germany, and Poland
  • Their global distribution and rapid evolution make them key index fossils for correlation

Why Buy From Us?

  • 100% genuine and responsibly sourced fossil
  • Supplied with a Certificate of Authenticity
  • Exact specimen pictured – no substitutes
  • Ideal for collectors, students, educators, or palaeontology 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.
