Species Information – Archaeolamna kopingensis

Archaeolamna kopingensis was an extinct species of mackerel shark, belonging to the order Lamniformes, a group that includes some of the most iconic predatory sharks in Earth’s oceans.

This species lived during the mid-Cretaceous seas and is known for its sharp, streamlined teeth adapted for catching fish and other marine prey. Archaeolamna teeth are highly sought after by collectors because they represent an ancient shark lineage that thrived long before modern great whites evolved.

Typical features include:

• A sleek triangular crown designed for efficient slicing

• Well-developed enamel preservation

• Strong root structure, giving the tooth excellent fossil integrity

Each tooth provides a direct glimpse into the life of one of the ocean’s most successful prehistoric predators.

Geological Context – The Gault Clay Formation

The Gault Clay is a marine sedimentary formation deposited approximately 100–110 million years ago during the Albian Stage of the Early Cretaceous.

At this time, southern Britain was submerged beneath a warm, shallow epicontinental sea teeming with marine life. Fine clay sediments settled slowly on the seafloor, creating ideal conditions for fossil preservation.

Folkestone is especially famous for producing:

• Shark and ray teeth

• Ammonites

• Marine reptiles

• Crustaceans and bivalves

The fossils from this locality are prized worldwide due to their scientific importance and high quality.

Depositional Environment & Preservation

This tooth fossil formed in a quiet marine environment where low oxygen conditions helped prevent decay and scavenging. Over millions of years, mineral-rich waters replaced the original biological material, preserving the tooth in durable fossil form.

The result is a striking and authentic specimen with strong geological character and excellent collectability.
