RARE 6.75″ Pictonia baylei Fossil Ammonite – Lower Kimmeridgian, Jurassic – Osmington Mills Dorset UK – COA – Alice Purnell Collection

£180.00

Offered here is a beautifully preserved and rare 6.75-inch specimen of Pictonia baylei, a fossil ammonite from the Lower Kimmeridgian Stage of the Late Jurassic, collected at the world-renowned site of Osmington Mills, Dorset, United Kingdom. This specimen is from the highly respected Alice Purnell Collection, and the photo shows the actual ammonite you will receive.

Geological Context:

  • Species: Pictonia baylei
  • Geological Period: Jurassic
  • Stage: Lower Kimmeridgian (~157.3 to 155.7 million years ago)
  • Location: Osmington Mills, Dorset, United Kingdom
  • Depositional Environment: Shallow marine shelf, primarily organic-rich clays and silts typical of the Kimmeridge Clay Formation, formed during a high sea-level phase in a warm, epicontinental sea

Taxonomic Classification:

  • Family: Aulacostephanidae
  • Superfamily: Perisphinctoidea
  • Order: Ammonitida
  • Suborder: Ammonitina
  • Formally Described By: Oppel, 1863

Morphological Features:

Pictonia baylei is recognised for its broad, evolute shell with strong, bifurcating ribs that curve gracefully across the flanks and venter. The ribs are well-defined and spaced, often displaying subtle tuberculation. The umbilicus is wide and open, typical of the genus, and the shell has a flattened to slightly rounded venter. This particular specimen retains crisp ribbing and well-defined ornamentation, making it a strong representative of the species.

Stratigraphic and Scientific Importance:

Pictonia baylei is a zonal index species in the British ammonite biozonation scheme, typically representing the Baylei Zone within the Lower Kimmeridgian. Its presence is instrumental in correlating marine sequences across the UK and northwestern Europe. The genus Pictonia is a hallmark of Late Jurassic ammonite evolution and is associated with the proliferation of highly ornamented forms in organic-rich, offshore settings.

Additional Details:

  • All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
  • Scale Rule Squares / Cube = 1cm. Please refer to the listing photo for exact size and visual detail.
  • This fossil is part of the carefully curated Alice Purnell Collection.

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.
