Description
This listing is for a 100% genuine fossil crab claw from the extinct genus Notopocorystes, discovered in the Cenomanian Stage of the Cretaceous Period in Sussex, United Kingdom. This fossil has been carefully selected for its scientific and display value. The photograph shows the exact specimen you will receive. The square scale cubes in the photo are 1cm each – please refer to the image for full sizing details.
All our fossils are authentic, sourced with integrity, and come with a Certificate of Authenticity.
Geological Context:
- Fossil Type: Crab Claw (Chela)
- Genus: Notopocorystes
- Order: Decapoda
- Superfamily: Portunoidea
- Family: Raninidae (tentative; taxonomic reassignment varies in literature)
- Geological Stage: Cenomanian (approx. 100.5 – 93.9 million years ago)
- Period: Cretaceous
- Locality: Sussex, United Kingdom
- Depositional Environment: Likely shallow marine sediment, typical of Cretaceous coastal and shelf environments in southern England
Morphology & Notable Features:
- The claw exhibits classic Notopocorystes morphology, including:
- Robust pincer structure
- Distinct curvature and articulation joint
- Well-preserved surface features, suitable for both study and display
- These claws were used for crushing or grasping prey and suggest the presence of a healthy benthic ecosystem.
Scientific Relevance: Notopocorystes is an extinct genus of brachyuran crabs often found in Cenomanian strata across Europe. Their presence contributes to our understanding of crustacean diversification and paleoecology in the early Late Cretaceous. The fossil record of crustaceans from the UK, especially Sussex, helps establish biozones and correlate marine sedimentary layers regionally.
Display & Collection: This fossil is ideal for:
- Educational use in geology or paleontology
- Collector’s display
- Natural history enthusiasts seeking UK-origin fossils
Included with Purchase:
- The exact fossil claw as shown
- Certificate of Authenticity
- Secure, protective packaging
