Original price was: £14.40.Current price is: £12.24.

This listing features a well-preserved Anahoplites planus ammonite fossil, collected from the classic marine deposits of the Gault Clay Formation at Folkestone, Kent, United Kingdom. This elegant ammonite dates to the Middle Albian Stage of the Cretaceous Period, approximately 105 million years ago.

The fossil shown is the exact specimen you will receive, chosen for its completeness, clear morphological features, and rarity. It’s ideal for collectors, educators, and natural history enthusiasts interested in England’s rich palaeontological heritage.

Geological & Palaeontological Details:

  • Species: Anahoplites planus
  • Fossil Type: Ammonite
  • Family: Hoplitidae
  • Superfamily: Hoplitoidea
  • Order: Ammonitida
  • Geological Period: Cretaceous
  • Stage: Middle Albian (approx. 107–104 million years ago)
  • Formation: Gault Clay
  • Location: Folkestone, Kent, UK
  • Biozone: Often found in the Anahoplites planus Zone, an important subunit within the Middle Albian biozonation of the Gault Clay
  • Depositional Environment: Open marine setting with deep clay-rich sea floor sediments. The low-energy and anoxic conditions allowed for exceptional fossil preservation, including intricate shell details.

Morphology & Features:

  • Anahoplites planus is distinguished by its broad, planispiral coiling, and relatively flat-sided shell profile
  • Exhibits fine, closely spaced ribs, generally simple or gently flexuous, without strong tuberculation
  • The whorl cross-section is compressed and rounded, with a clean ventral edge
  • This clean morphology sets it apart from more heavily ornamented ammonites of the same age

Notability: Anahoplites planus is a valuable biostratigraphic marker for the Middle Albian and is especially prized from Folkestone’s Gault Clay, one of the most famous fossil localities in Europe. First described by Spath (1923), its well-defined features and limited stratigraphic range make it important to researchers and collectors alike.

Additional Details:

  • All our fossils are 100% genuine specimens
  • Comes with a Certificate of Authenticity
  • The photo shows the exact fossil for sale
  • Scale cube = 1cm – please refer to images for full sizing

This ammonite offers a superb window into the marine ecosystems of the Cretaceous and represents a striking and scientifically meaningful addition to any fossil collection.

Description

Fossil Identification

This listing features a fossil ammonite identified as Anahoplites planus. The specimen is associated with Gault Clay of Middle Albian age within the Cretaceous Period, and the listed location is Folkestone, Kent, United Kingdom. It is a geological and palaeontological collectible suited to fossil enthusiasts, ammonite collectors, educational displays and natural history collections.

Anahoplites planus is an ammonite, an extinct marine cephalopod group that lived in the oceans during the Mesozoic Era. Ammonites are especially valued by collectors because their preserved shells provide a direct connection to ancient marine environments and are useful in studying the geological history of sedimentary rocks. This identification places the fossil within the diverse ammonite record of the Cretaceous.

Geological Context

The Middle Albian represents a stage of the Early Cretaceous, a time when marine environments covered substantial areas of what is now southern England. Gault Clay is a well-known marine clay deposit associated with Cretaceous geological history in the region. Fossils from this context are of interest for the way they reflect ancient marine life and the changing environments recorded in the sediments.

Folkestone, in Kent, is an important area for Cretaceous geology and is widely recognised by collectors and students of palaeontology for its fossil-bearing deposits. The combination of Anahoplites planus, Gault Clay, Middle Albian age and Folkestone locality makes this an appealing piece for anyone researching British Cretaceous fossils or building a themed ammonite collection.

Collector and Display Appeal

This fossil can be used as a conversation piece in a home collection, geological display, classroom resource or natural history cabinet. It offers an accessible way to explore ammonites, Cretaceous marine ecosystems and the geological record of Kent. The named identification and geological context also make it suitable for collectors who organise specimens by genus, species, stratigraphic age, formation or locality.
