British Chalk Shark Tooth - Plicatolamna crassidens Fossil - Santonian Cretaceous, Lewes, Sussex, UK - Certified Genuine Marine Fossil

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.

British Chalk Shark Tooth - Plicatolamna sulcata Fossil - Santonian, Upper Cretaceous - Southerham Quarry, Lewes, Sussex, UK - Certified Authentic Fossil

This listing is for an authentic fossil shark tooth from the extinct species Plicatolamna sulcata, collected from the Santonian-aged Chalk of the Southerham Lime Kiln Quarry, near Lewes, East Sussex, UK. This geologic formation dates to the Upper Cretaceous period, approximately 86–83 million years ago, when a shallow epicontinental sea covered much of Europe.

Plicatolamna sulcata was an extinct lamniform shark that inhabited these warm tropical seas. It is known for its relatively slender, smooth-edged triangular teeth, which differ subtly from the more robust P. crassidens. These sharks were likely fast-moving predators or scavengers, playing a vital role in the Late Cretaceous marine ecosystem.

The British Chalk is internationally famous for its fossil preservation, especially of marine invertebrates and vertebrates. The Southerham Quarry is one of the most important fossil localities in the UK, having produced an abundance of shark teeth and other marine remains from the Santonian stage.

This particular specimen has been carefully prepared and is a fine example of this rare species. It's an excellent addition for collectors, educators, or enthusiasts interested in the diversity of Cretaceous marine life.
