Fossil Species – Archaeolamna kopingensis

Archaeolamna kopingensis is an extinct species of mackerel shark from the order Lamniformes, an ancient lineage that includes many of today’s most formidable open-ocean predators. This species lived during the Early Cretaceous seas and is known primarily from its distinctive fossil teeth.

Archaeolamna teeth are prized for their elegant form and sharp predatory design. Notable morphological features typically include:

• A triangular crown with strong cutting capability

• Smooth enamel surface with excellent fossil preservation

• Well-defined root structure for secure jaw attachment

• Adaptation for grasping and slicing marine prey

These teeth represent a direct trace of a shark that once hunted in the warm prehistoric seas covering southern Britain over 100 million years ago.

Geological Setting – The Gault Clay Formation (Albian Stage, Early Cretaceous)

The Gault Clay dates to the Albian Stage of the Early Cretaceous, approximately 100–110 million years ago. During this time, the area now known as Kent lay beneath a shallow, tropical marine shelf sea rich in life.

Fine clay sediments settled slowly on the seabed, creating ideal conditions for fossilisation. Fossils from this deposit are often exceptionally detailed, making Folkestone one of Europe’s most important Cretaceous fossil sites.

Common associated fossils from the Gault Clay include:

• Shark and ray teeth

• Ammonites used for biostratigraphic zoning

• Marine molluscs and crustaceans

• Fish remains and occasional reptile material

This gives each specimen both scientific and collectible importance.

Depositional Environment & Fossil Preservation

Archaeolamna teeth fossilised after being naturally shed during the shark’s lifetime. The tooth became buried in soft marine clay on the sea floor, protected from erosion. Over millions of years, mineral-rich groundwater replaced the original biological material, preserving the tooth as a permanent fossil.

The low-energy depositional environment of the Gault Clay allows fossils to retain crisp details, including crown edges and enamel texture, making these shark teeth highly desirable among collectors.
