This listing presents a RARE 8-inch Fossil Ammonite, identified as Puzosia mayoriana dibley, from the Turonian Stage of the Cretaceous Period. This spectacular fossil was discovered at Southerham, Sussex, United Kingdom, and originates from the esteemed Alice Purnell Collection, known for its premium, scientifically documented specimens.

Geological Details:

  • Locality: Southerham, Sussex, United Kingdom
  • Geological Period: Cretaceous
  • Geological Stage: Turonian (~93.9 to 89.8 million years ago)
  • Depositional Environment: Calm, offshore chalk sea environment with fine-grained calcareous sedimentation
  • Formation: Upper Chalk (Lower to Middle Turonian strata of southern England)

Paleontological Context: Puzosia is a genus within the Desmoceratidae Family, featuring strongly ribbed, planispiral ammonites. Puzosia mayoriana is well-represented in Turonian sequences, and the variety dibley is a regionally significant form. It is often used in biostratigraphic correlation and paleoenvironmental reconstruction.

  • Order: Ammonitida
  • Superfamily: Desmoceratoidea
  • Family: Desmoceratidae
  • Genus: Puzosia
  • Species: mayoriana
  • Variety/Subspecies: dibley
  • Biozone: Turonian – potentially within the Mammites nodosoides or Collignoniceras woollgari biozones depending on stratigraphic level
  • Formally Described by: Wright & Wright (subspecies attribution)

Morphological Features:

  • Large, 8-inch shell with strongly developed radial ribs
  • Planispiral coiling with involute form
  • Rounded venter with minimal tuberculation

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
