RARE Fossil Crab Claw & Fragments – Notopocorystes – Cenomanian, Cretaceous – Sussex UK – Authentic Crustacean Fossil with COA

Description This listing features a RARE fossil crab claw and associated fragments from the extinct genus Notopocorystes, discovered in the Cenomanian-aged deposits of the Cretaceous Period in Sussex, United Kingdom. This is an authentic fossil from an ancient marine crustacean, showcasing preserved morphology of the claw and exoskeletal remains. These fossils are becoming increasingly scarce and represent a valuable glimpse into the marine ecosystems of the mid-Cretaceous. All of our Fossils are 100% Genuine Specimens and come with a Certificate of Authenticity. The specimen in the photo is the exact one you will receive. Please refer to the scale cube (1cm per square) in the image for full sizing. Geological & Scientific Details: Fossil Type: Marine Decapod (Crab) Genus: Notopocorystes Geological Period: Cretaceous Geological Stage: Cenomanian (approximately 100.5 to 93.9 million years ago) Location Found: Sussex, United Kingdom Depositional Environment: Shallow epicontinental marine shelf—chalk and marl sedimentary systems, indicative of warm, nutrient-rich seas with carbonate deposition Morphological Features: Preserved pincer (chela) from the crab’s claw Dense exoskeletal fragments with granulated texture Some ornamentation and tubercles possibly preserved on surface Order: Decapoda Infraorder: Brachyura Superfamily: Notopocorystoidea Family: Notopocorystidae Identification Notes: Originally described by paleontologists in the 19th century from similar Cenomanian chalk deposits of southern England and northern France, Notopocorystes species are well-documented Cretaceous decapods. Palaeontological Importance: Fossil crabs from the Cretaceous are far less common than ammonites or other invertebrates. This specimen is representative of a time when early modern crustaceans were beginning to diversify in the fossil record. Its preservation in the English chalk beds provides insights into the benthic fauna of the mid-Cretaceous seas. This piece is ideal for fossil enthusiasts, collectors of marine invertebrates, educational use, or as a unique natural display item. Crab fossils like this—especially complete or partial claws—are rarely offered in such quality and provenance.
