Isurolamna affinis Shark Tooth British Eocene Fossil Beltinge Kent Woolwich Beds | Paleocene Certified Genuine Specimen

Original price was: £31.20.Current price is: £24.96.

This listing features a genuine Isurolamna affinis shark tooth fossil from the Woolwich Beds, dating back to the Paleocene-Eocene transition (~56 million years ago). This well-preserved fossil was found in Beltinge, Kent, UK, a location famous for producing high-quality fossil shark teeth from ancient marine deposits.

What is Isurolamna affinis?

Isurolamna affinis was an extinct species of lamniform shark, closely related to modern mako sharks and great whites. This species thrived in the warm shallow seas of the early Paleogene period, feeding on fish and marine invertebrates. Their teeth are characterized by a slender, slightly curved central cusp with fine cutting edges and small lateral cusplets, which allowed them to effectively grasp and tear prey.

This particular specimen exhibits excellent preservation, displaying the classic tooth shape of Isurolamna affinis, with sharp, well-defined cusps and fine enamel detail, making it a fantastic addition to any collection.

Fossil Details:

✅ Species: Isurolamna affinis

✅ Fossil Type: Shark Tooth

✅ Geological Formation: Woolwich Beds

✅ Geological Age: Paleocene-Eocene (~56 million years old)

✅ Location: Beltinge, Kent, UK

✅ Collection: Alice Purnell Collection – One of the world’s largest ammonite collections

Geological Significance:

The Woolwich Beds are a significant Paleocene-Eocene marine deposit, formed in shallow coastal and estuarine environments. This period marks an important phase in the evolution of sharks, as species diversified and adapted to the changing marine ecosystem following the end-Cretaceous mass extinction. These fossil-rich beds preserve a variety of early Cenozoic marine life, including sharks, rays, mollusks, and other invertebrates.

Why This Fossil is Special:

🔹 Rare British Shark Tooth – Fossils of Isurolamna affinis are much less common than those of other Eocene shark species.

🔹 Exceptional Preservation – Crisp enamel detail, sharp cusp, and well-preserved lateral cusplets.

🔹 Museum-Grade Specimen – Sourced from the renowned Alice Purnell Collection.

🔹 Guaranteed Authenticity – 100% genuine fossil, accompanied by a Certificate of Authenticity.

📏 Scale Rule / Cube = 1cm – Please refer to the photos for full sizing details.

📸 What You See Is What You Get – The specimen in the photos is the exact fossil you will receive.

This rare British Eocene shark tooth fossil is a must-have for fossil collectors, educators, and paleontology enthusiasts, offering a direct connection to the fascinating marine ecosystems of the early Cenozoic era.

Description

Fossil Identification

This listing presents an Isurolamna affinis shark tooth, identified as a British Eocene fossil from Beltinge, Kent. The specimen is associated with the Woolwich Beds, with the supplied identification also recording Paleocene and Eocene. Its scientific name makes it an appealing addition for collectors interested in fossil sharks, palaeontology and the geological history of Britain.

The photograph shows the actual specimen you will receive.

Geological Context

The Woolwich Beds are a geological unit associated with the London Basin and are known for fossil-bearing sediments. Shark teeth are among the most frequently encountered fossil remains of ancient sharks because teeth are composed of durable mineralised tissues that can survive after other parts of the animal have decayed. Each tooth provides a direct fossil record of shark life in the past and can be studied alongside the surrounding geological material and other fossils from the same deposits.

The supplied record identifies this tooth with both Paleocene and Eocene terminology. These are successive intervals within the Palaeogene Period, a major chapter of Earth history that followed the end-Cretaceous extinction. Fossil shark material from this broad part of the geological record is of interest because it contributes to the study of shark diversity and marine ecosystems through time.

Collector Interest

An Isurolamna affinis tooth offers a focused and accessible way to explore fossil shark taxonomy and the history of British geology. Shark teeth are popular with beginners, advanced fossil collectors, educational displays and anyone interested in palaeontology. The identification, locality and geological association give this specimen useful interpretive value when catalogued as part of a personal collection.

The specimen can be displayed as a natural history object or used as a reference piece when comparing fossil shark teeth from different geological periods and localities. Its named identification makes it particularly suitable for collectors who value labelled and documented specimens rather than unclassified fossil material.

Certificate and Authenticity

This Fossil is a genuine specimen and Includes a Certificate of Authenticity lifetime guarantee generic card.

The certificate wording supplied with this fossil provides accompanying documentation for collectors and helps preserve the specimen’s identification and authenticity details. Please retain the certificate with the fossil as part of its collection record.
