Striatolamia macrota Shark Tooth Fossil – Early Eocene Sparnacian – Oldhaven Fm. – Abbey Wood London UK

Description Striatolamia macrota Shark Tooth Fossil – Early Eocene (Sparnacian Stage) – Oldhaven Formation, Bracklesham Beds – Abbey Wood, London, England This listing features a genuine Striatolamia macrota shark tooth fossil, recovered from the Oldhaven Formation of the Bracklesham Beds at Abbey Wood, a classic fossil site in London, UK. Dating to the Sparnacian Stage of the Early Eocene, this beautifully preserved specimen represents one of the most common large shark species of the Paleogene seas. Fossil Type: Shark Tooth Species: Striatolamia macrota Order: Lamniformes Family: Odontaspididae (sand tiger sharks) Class: Chondrichthyes (cartilaginous fishes) Geological Stage: Early Eocene – Sparnacian (~55 million years ago) Formation: Oldhaven Formation, Bracklesham Group Location: Abbey Wood, London, England, UK Depositional Environment: Shallow marine, warm subtropical shelf with fine sands and organic-rich sediments Biozone/Zone: Correlates broadly with NP10–NP12 calcareous nannoplankton zones Morphology Features: Striatolamia macrota teeth are known for their long, slender central cusp with distinctive fine vertical striations (from which the genus name is derived), and a pair of small lateral cusplets. The roots are robust and bilobed, indicating strong attachment for feeding. This species likely fed on soft-bodied prey such as fish and squid, using its narrow, non-serrated teeth to grasp rather than slice. Geological Context: The Oldhaven Formation, part of the Bracklesham Beds, represents a dynamic post-Cretaceous marine environment rich in elasmobranch fossils. Abbey Wood is particularly noted for its abundance and diversity of early Paleogene fish remains, including sharks, rays, and bony fish. These sediments reflect conditions in a warm, shallow sea during one of the most important periods in early Cenozoic marine evolution. Condition: Excellent enamel and root preservation. Natural wear consistent with fossilisation. Specimen photographed is the exact item you will receive. Scale Rule Squares / Cube = 1cm for reference. Important Note: All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity. An iconic and well-preserved example of an early Eocene sand tiger shark tooth—ideal for collectors, display, or educational reference.
