Striatolamia macrota Shark Tooth Fossil – London Clay Formation – Early Eocene – Isle of Sheppey, United Kingdom

This listing features a genuine Striatolamia macrota shark tooth fossil, discovered in the classic marine deposits of the London Clay Formation on the Isle of Sheppey, UK. This extinct lamniform shark lived during the Early Eocene, around 50–54 million years ago, in the warm subtropical seas that once covered much of what is now southeast England.

Fossil Type: Shark Tooth

Species: Striatolamia macrota

Order: Lamniformes

Family: Odontaspididae (sand tiger sharks)

Class: Chondrichthyes (cartilaginous fishes)

Geological Stage: Eocene – Ypresian (~50–54 million years ago)

Formation: London Clay Formation

Location: Isle of Sheppey, Kent, United Kingdom

Depositional Environment: Shallow subtropical marine basin with clay-rich silts and sands, excellent for vertebrate fossil preservation

Biozone/Zone: Correlates broadly with NP12–NP14 nannoplankton zones of the early Eocene

Morphology Features: Striatolamia macrota teeth are characterised by their long, slender crown with smooth cutting edges and fine vertical striations along the enamel surface. Each tooth typically features a pair of lateral cusplets at the base of the main cusp, and a bilobed root that is symmetrical and robust. These adaptations were ideal for catching and gripping fish and soft-bodied marine prey.

Geological Context: The London Clay Formation is one of the most famous fossil-rich marine deposits in Europe, particularly known from the Isle of Sheppey. It has yielded an extraordinary array of marine fossils including sharks, rays, fish, reptiles, birds, and invertebrates. Striatolamia macrota is among the most frequently found shark teeth from this unit, reflecting its dominance in early Eocene seas.

Condition: Excellent enamel preservation, visible striations, and root structure as shown in photographs. Typical natural wear for Sheppey specimens. Scale Rule Squares / Cube = 1cm – refer to photo for full size reference. The specimen shown is the exact one you will receive.

Important Note:

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.

A classic and scientifically important fossil tooth from Britain’s early Paleogene seas—ideal for fossil collectors, educators, and enthusiasts of ancient marine life.

Eocene Information

The Eocene Period (56–33.9 million years ago) was a time of warm global temperatures and the rapid evolution of mammals following the extinction of the dinosaurs. The climate was hot and humid, with lush rainforests covering much of the planet, even near the poles. Mammals diversified into new ecological roles, with early primates, whales (like Basilosaurus), large herbivores, and carnivores emerging. Birds and reptiles also thrived, and the first grasses began spreading, setting the stage for later grassland ecosystems. By the late Eocene, the Earth’s climate cooled significantly, leading to the formation of the first Antarctic ice sheets and the eventual transition to the drier, cooler Oligocene Period.
