This listing features a well-preserved fossil echinoid (sea urchin) of the species Holectypus depressus, collected from the Cornbrash Formation in Somerset, United Kingdom. This authentic Jurassic marine invertebrate fossil is provided with a Certificate of Authenticity, and the photo shows the exact specimen you will receive.

Holectypus depressus belongs to:

  • Order: Holectypoida
  • Family: Holectypidae

This echinoid lived during the Bathonian Stage of the Middle Jurassic Period, approximately 168–166 million years ago. The Cornbrash Formation consists of marine shelly limestones and mudstones deposited in a shallow marine, inner shelf environment that supported a diverse array of invertebrate life.

Morphological Features:

  • Flattened, oval test (shell) with a low dome profile
  • Petaloid ambulacra with finely impressed pore pairs
  • Oral surface flattened with distinct peristome
  • Smooth to lightly granulated surface, often symmetrical

These features suggest an infaunal or semi-infaunal lifestyle, with the organism likely burrowing or living on soft marine sediments.

  • Fossil Type: Echinoid (Sea Urchin) Test
  • Geological Unit: Cornbrash Formation
  • Geological Age: Middle Jurassic (Bathonian Stage)

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
