Discovery and Preparation

Your fossil was discovered by our dedicated team members, Alister and Alison, ensuring full provenance and traceability. Following recovery, the specimen was expertly cleaned, stabilised, and professionally prepared by Alison, preserving its natural features while enhancing visibility of key anatomical details. This careful preparation ensures the fossil remains both scientifically valuable and visually striking for display or collection.

Geological Context – Bouldnor Formation, Oligocene

The Bouldnor Formation dates to the Oligocene epoch, approximately 23–34 million years ago, a period marked by significant climatic transition and the development of diverse ecosystems. Hamstead Cliff is particularly well known for its rich assemblage of freshwater and estuarine fossils, including reptiles, mammals, and plant remains. The depositional environment of this formation reflects a low-energy lagoonal to estuarine setting, ideal for the preservation of delicate skeletal structures such as turtle carapaces.

About Trionyx – Softshell Turtles

The genus Trionyx belongs to the family Trionychidae, commonly known as softshell turtles. These turtles are characterised by their reduced, flattened carapace and lack of the hard scutes seen in other turtle groups. Instead, their shells are covered by leathery skin, giving them increased flexibility and hydrodynamic efficiency. Fossil specimens such as this provide valuable insight into the evolutionary history of softshell turtles and their adaptation to aquatic environments.

Morphology and Notable Features

This carapace fragment displays the distinctive flattened structure typical of Trionychid turtles, with subtle textural detail that reflects the original bone structure beneath the soft outer covering. The fossilisation process has preserved key surface features, allowing collectors and enthusiasts to appreciate the natural form and biological function of the shell. Each specimen is unique, with natural variation in preservation, colour, and matrix adding to its individual character.

Authenticity and Display Appeal

This fossil is not only a scientifically interesting piece but also an attractive display item, suitable for collectors, educators, or anyone with an interest in natural history. Its provenance, preparation quality, and geological significance make it a standout addition to any fossil collection. Full sizing can be confirmed via the provided photographs, ensuring complete transparency before purchase.
