This is a rare and well-preserved Echinocorys scutata var. "gravesi" Fossil Echinoid (Sea Urchin) from the Lower Chalk Formation of the Cretaceous Period, discovered in Peacehaven, Sussex, UK. This scientifically significant fossil showcases the detailed structure of this extinct echinoid species, making it an excellent addition to any fossil collection.
Echinocorys scutata var. "gravesi" is a variety of heart urchins belonging to the family Holasteridae. These echinoids thrived in the chalk seas of the Late Cretaceous, living buried in soft marine sediments. Their hard tests (shells) were well-adapted for burrowing, and their fossils are commonly found in chalk deposits across Europe. This variety, "gravesi," is particularly notable for its distinct shape and structural features, which help paleontologists understand the evolution of echinoids in Mesozoic marine ecosystems.
