CLYPEUS PLOTTI Fossil Echinoid Sea Urchin Jurassic Inferior Oolite Cheltenham UK Authentic Specimen

Original price was: £12.00.Current price is: £10.80.

This listing features a classic and well-preserved fossil echinoid (sea urchin) of the species Clypeus plotti, collected from the Inferior Oolite Formation, near Cheltenham, Gloucestershire, UK. This authentic Jurassic specimen comes with a Certificate of Authenticity, and the photos show the exact fossil you will receive.

Clypeus plotti is one of the most iconic echinoids of the British Jurassic. It is part of the:

  • Order: Clypeasteroida
  • Family: Clypeidae

These echinoids lived during the Bajocian Stage of the Middle Jurassic, approximately 170–168 million years ago. The Inferior Oolite Group, where this fossil was found, represents shallow marine carbonate platforms—a warm, tropical sea teeming with invertebrate life.

This region of the Cotswolds is famed for yielding some of the best-preserved specimens of Clypeus, which were once so common and distinctive that they were colloquially known as “pound stones” or “pound echinoids” due to their disc-like shape and abundance.

Morphological Features:

  • Large, thick discoidal test (shell) with a slightly domed profile
  • Central apical system with petaloid ambulacra
  • Radial symmetry with subtle ornamentation
  • Generally smooth surface with five faint petal-like grooves

These echinoids lived buried just beneath the sediment surface and were likely deposit feeders, sifting nutrients from the surrounding substrate.

Specimen Information:

  • Species: Clypeus plotti
  • Fossil Type: Echinoid (Sea Urchin) Test
  • Geological Unit: Inferior Oolite Formation
  • Geological Age: Middle Jurassic (Bajocian Stage)
  • Location: Cheltenham, Gloucestershire, UK
  • Depositional Environment: Shallow warm marine shelf (oolitic limestone)
  • Family: Clypeidae

This is an excellent specimen for any fossil enthusiast or collector of Jurassic marine invertebrates. It also makes a great educational example of Mesozoic echinoderm evolution and shallow marine ecosystems.

Scale rule squares/cube = 1cm. Please refer to the photos for full sizing and detail.

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.

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.
