£60.00

Discover a stunning and RARE example of Acanthoceras jukesbrowni, a beautifully preserved fossil ammonite from the Lower Cenomanian stage of the Cretaceous Period, unearthed from the renowned locality of Southerham, United Kingdom. This particular specimen comes directly from the Alice Purnell Collection and is a carefully curated fossil showing exquisite morphological details. The photo in the listing is of the actual fossil you will receive.

Geological Context:

  • Species: Acanthoceras jukesbrowni
  • Geological Period: Cretaceous
  • Stage: Lower Cenomanian (~100.5 to 93.9 million years ago)
  • Locality: Southerham, East Sussex, UK
  • Depositional Environment: Shallow marine carbonate platform, indicative of warm, tropical seas with high sedimentation rates typical of the early Late Cretaceous transgressions.

Taxonomic Details:

  • Family: Acanthoceratidae
  • Superfamily: Acanthoceratoidea
  • Order: Ammonitida

Morphological Features: Acanthoceras jukesbrowni is notable for its heavily ornamented shell with prominent tubercles (nodes) and strong, pronounced ribs. These features likely helped in buoyancy control and possibly defense against predators. This specimen exhibits exceptional preservation of these diagnostic features, including the sharp ribbing and spiny projections typical of the genus.

Rarity & Significance: This is a rare and highly collectable ammonite, both due to its specific taxon and the quality of preservation from the Southerham locality. The Lower Cenomanian rocks in this area are known for their fossiliferous chalk and marls, which have yielded scientifically significant ammonite assemblages.

Additional Information:

  • All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.
  • Scale Rule Squares / Cube = 1cm: Full sizing available in the photo.
  • From the prestigious Alice Purnell Collection, this fossil is a one-of-a-kind collector’s item.

Ideal for collectors, educators, or as a standout display piece, this ammonite is not only scientifically valuable but aesthetically impressive.

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.
