Echinocorys scutata Fossil Echinoid Cretaceous Chalk Saltdean Sussex UK Genuine Specimen

Description

Echinocorys scutata Fossil Echinoid from Saltdean, Sussex, UK

This listing offers a fine Echinocorys scutata fossil echinoid, discovered in the Cretaceous chalk beds of Saltdean, Sussex, United Kingdom. Echinocorys is one of the most iconic and scientifically important echinoids from the chalk, often known as the “Chalk Heart Urchin.” The specimen shown in the photographs is the exact fossil you will receive, with a 1 cm scale cube provided for reference. All of our fossils are 100% genuine specimens and include a Certificate of Authenticity.

Geological Age and Setting – Upper Cretaceous Chalk

This echinoid originates from the Upper Cretaceous period, approximately 90–66 million years ago, when much of southern England lay beneath a shallow tropical sea. Over time, the skeletal remains of countless microscopic algae called coccolithophores accumulated on the seafloor, compacting into the famous white chalk deposits of southern Britain.

The chalk of Sussex, including Saltdean, has yielded some of the finest examples of echinoids, ammonites, sponges, and other marine life. These deposits form part of the same geological system as the White Cliffs of Dover, a world-renowned natural landmark.

Species and Classification

• Genus: Echinocorys
• Species: scutata
• Class: Echinoidea
• Order: Holasteroida
• Family: Holasteridae

Echinocorys scutata is one of the most abundant echinoids in the chalk and has been widely studied since the 18th century. Its consistent presence and distinctive morphology make it an excellent index fossil, used by geologists to divide and correlate chalk strata across Europe.

Morphological Features

This specimen of Echinocorys scutata exhibits several defining characteristics:

• Shape: A sub-ovate, heart-like form with a gently domed upper surface.
• Ambulacra: Five petal-like grooves radiating across the top, forming a distinct star-shaped pattern.
• Test: A robust calcareous shell, often exceptionally well preserved in chalk.
• Adaptation: It lived semi-buried in the soft chalk seabed, filtering food particles from surrounding water and sediment.

These traits not only make it an important palaeontological specimen but also give it strong aesthetic appeal for display.

Stratigraphy and Scientific Importance

Echinocorys scutata is a key ammonite-associated echinoid of the Upper Cretaceous chalk biozones, providing excellent stratigraphic markers for correlating rocks across northwestern Europe. Its evolutionary changes through time are well documented, making it essential for refining the subdivision of the chalk sequence and reconstructing marine ecosystems of the Late Cretaceous.

Collector and Display Value

• Collectors appreciate this fossil for its abundance in British chalk, combined with its classic and recognisable form.
• Researchers and educators use it as a key species for teaching stratigraphy and Cretaceous palaeoecology.
• As a display fossil, its star-shaped grooves and iconic heart-like shape make it a striking and timeless addition to any collection.
