RARE 10″ Proplanulites Fossil Ammonite | Lower Callovian Jurassic | Manor Farm Wiltshire UK | Certified Genuine Specimen

£600.00

An impressive and rare 10-inch fossil ammonite: Proplanulites sp., from the Lower Callovian Stage of the Middle Jurassic, collected from the renowned fossil-rich beds of Manor Farm, Wiltshire, United Kingdom. This exceptional example represents an important evolutionary stage in mid-Jurassic ammonite development, making it a desirable piece for collectors and educational display.

The specimen shown is the exact fossil you will receive, photographed with a 1cm scale cube for size reference. Please refer to the images for detailed condition and dimensions.

 

Geological & Palaeontological Information:

  • Fossil Type: Ammonite
  • Genus: Proplanulites
  • Geological Period: Jurassic
  • Stage: Lower Callovian (~165 to 163 million years ago)
  • Location: Manor Farm, Wiltshire, England, UK
  • Depositional Environment: Shallow marine shelf; fine calcareous mudstones and silts from the Oxford Clay Formation
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Kosmoceratidae
  • Biozone (Inferred): Likely within the Macrocephalites herveyi or Bullatimorphites bullatus Zones of the Lower Callovian, based on stratigraphy at Manor Farm

 

Morphological Features:

  • Moderately involute shell with smooth or weakly ribbed flanks
  • Broad, rounded whorls with a flattened venter in later growth stages
  • Sutures typically complex, though less ornamented than later Kosmoceratid forms
  • Potential faint keel or ventrolateral tubercles in some specimens

 

Notable Points:

  • Proplanulites is considered transitional in form, marking key ammonite evolution in the Callovian
  • Manor Farm is a scientifically significant site for Jurassic marine invertebrates
  • Large, display-sized examples of Proplanulites are seldom available on the fossil market

 

Why This Fossil is Special:

  • Rare ammonite genus from a globally important stratigraphic interval
  • Excellent size and preservation from a UK heritage site
  • Supplied with a Certificate of Authenticity
  • 100% genuine and ethically sourced fossil
  • Ideal for collectors, academic institutions, or interior display

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.
