Description
Offered here is a well-preserved and authentic fossil shark tooth from the extinct species Plicatolamna crassidens, discovered in the renowned Southerham Lime Kiln Quarry, near Lewes, Sussex, UK. This specimen comes from the Santonian Stage of the Upper Cretaceous, approximately 86 to 83 million years ago, and is part of the classic British Chalk deposits.
Plicatolamna crassidens is a lesser-known species of extinct mackerel shark that belonged to the family Lamnidae, and it inhabited the warm, shallow seas of the Late Cretaceous. These sharks are part of the order Lamniformes, which includes modern relatives like mako and great white sharks. Their fossilised teeth are characterised by their robust triangular shape, prominent striations, and sometimes faint lateral cusplets.
The British Chalk of the Cretaceous period is a globally significant geological formation known for its outstanding preservation of marine fauna. The Santonian deposits at Southerham Quarry have yielded a diverse array of marine fossils, from invertebrates to vertebrates such as fish and sharks. This site is especially significant for those studying the diversity and evolution of Cretaceous marine ecosystems.
This particular tooth is a fine example of its kind and provides both aesthetic and scientific value. Whether you’re an established collector, educator, or paleontology enthusiast, it is a wonderful addition to any fossil collection.
