Sylvestrilamia teretidens Shark Tooth Fossil – Early Eocene – Oldhaven Formation – Abbey Wood, London UK

Description Sylvestrilamia teretidens Shark Tooth Fossil – Early Eocene (Sparnacian Stage) – Oldhaven Formation – Bracklesham Beds – Abbey Wood, London, England This genuine fossil is a well-preserved shark tooth from Sylvestrilamia teretidens, an extinct lamniform shark from the Early Eocene, collected from the famous Abbey Wood locality in London, UK. The specimen was preserved in the Oldhaven Formation, part of the Bracklesham Beds, a rich marine fossil deposit known for its abundance of Eocene fish, shark, and ray remains. Fossil Type: Shark Tooth Species: Sylvestrilamia teretidens Order: Lamniformes Family: Odontaspididae (sand tiger sharks) Class: Chondrichthyes (cartilaginous fishes) Geological Stage: Early Eocene – Sparnacian (~55 million years ago) Formation: Oldhaven Formation, part of the Bracklesham Group Location: Abbey Wood, London, England, United Kingdom Depositional Environment: Shallow marine shelf – warm, subtropical nearshore lagoonal and estuarine environment with high organic preservation potential Biozone/Zone: Typically part of NP10–NP12 nannoplankton zones (if correlated) Morphology Features: Sylvestrilamia teeth are slender, with smooth-edged, narrow crowns and a long, straight or slightly curved central cusp. They lack serrations and often have small lateral cusplets, a feature typical of sand tiger shark relatives. These teeth are well-suited to grasping slippery prey, such as fish and cephalopods. Their glossy enamel and root structure are diagnostic. Geological Context: The Abbey Wood fossil beds, part of the Bracklesham Group, are a historic and protected fossil site that has yielded a wide range of early Eocene marine vertebrates and invertebrates. The Oldhaven Formation, specifically, consists of glauconitic sands and silts deposited in a shallow marine to marginal marine setting. It provides exceptional preservation of elasmobranch remains (sharks and rays). Condition: Excellent detail as shown in photographs. Scale Rule Squares / Cube = 1cm.
