Description
Featured here is a fascinating trace fossil of a crustacean burrow, recovered from the London Clay Formation, dated to the Eocene Epoch (~56 to 47.8 million years ago), from Hensbrook Beach, Isle of Sheppey, Kent, United Kingdom. This trace fossil captures the preserved evidence of ancient crustacean activity, offering a rare glimpse into paleo-behaviour preserved in sediment.
Geological Context:
- Formation: London Clay
- Age: Eocene (Ypresian Stage)
- Location: Hensbrook Beach, Isle of Sheppey, Kent, UK
- Depositional Environment: Shallow marine, estuarine to coastal shelf, warm tropical climate with significant sedimentation from river deltas and tidal systems
- Lithology: Fine-grained marine clays, rich in fossils including fish, sharks, plants, and invertebrate traces
Trace Fossil Features:
- Identified as a crustacean burrow, likely formed by decapod crustaceans such as ghost shrimps or mud lobsters
- Characterised by horizontal to subvertical tubes, often smooth-walled or coated with bioturbated sediment
- May display branching networks or chambers, indicative of complex burrowing behaviour
- Represents a form of ichnofossil, documenting behavioural activity rather than body form
Scientific & Collector Interest:
- Crustacean trace fossils from the London Clay are relatively uncommon and hold value in reconstructing paleoecology and sedimentary environments of early Eocene marine settings
- Offers unique insight into the ethological category of dwelling structures (Domichnia)
- Well-preserved and educational, ideal for collections focused on trace fossils or paleo-behavioural studies
Authenticity Guaranteed: This is a 100% genuine natural fossil and is sold with a Certificate of Authenticity. The specimen shown in the photos is the exact item you will receive, shown with a 1cm scale cube for reference. Please review all images for exact size and detail.
An excellent opportunity to own a well-preserved trace fossil from one of the UK’s most famous Eocene fossil localities, perfect for collectors, educators, and enthusiasts of ancient life.
