Beachcombing - A Fairy Loaf

I found this lovely flint fossil echinoid on the beach between Marske and Redcar. The fossil is smooth to the touch and heavy in the hand, beautiful dense flint with an unmistakable five pointed star on its upper surface, it’s a first for me. Fossil echinoids are not uncommon finds in areas with chalk bedrock but this is the first example that I have found on our beaches. Fossil echinoids have…

Notable: Echinocorys scutata is among the most iconic and widely distributed echinoid species in European chalk; the gravesi subspecies is particularly noted from Kent and adjacent areas

Biozone: Likely associated with Santonian inoceramid and foraminiferal zones within the UK Upper Chalk

Identifier: First described in 19th-century British paleontological literature; a reference species for zonal and paleoenvironmental studies in the Chalk

Fossil Flint Echinoid (Shepherd’s Crown) – Cretaceous Chalk, Seaford Head, Sussex UK – British Sea Urchin Fossil with Certificate

This listing features a genuine Fossil Flint Echinoid, often affectionately referred to as a "Shepherd’s Crown", collected from the Cretaceous Chalk deposits of Seaford Head, Sussex, UK. These iconic echinoid fossils are preserved in flint—a result of millions of years of mineral replacement after the creature’s death on the seabed.

The chalk cliffs of Seaford Head are part of the Upper Cretaceous sequence of southern England, dating back approximately 100 to 66 million years ago. The echinoid species, most likely within the genus Conulus or Micraster, were marine invertebrates related to modern sea urchins. Over time, the original calcite skeletons were dissolved and replaced by silica to form the hard flint fossils we find today.

These echinoids are famed for their distinct five-point symmetry and domed shape, often resembling a crown or star. Flint echinoids are a sought-after classic British fossil due to their excellent preservation, high contrast appearance, and regional collectability.

This specimen was discovered by our own team members, Alister and Alison, on 24 March 2025, and has been expertly cleaned, prepped, and treated by Alison for optimal presentation and preservation.
