Description
Step back in time and behold the extraordinary beauty of the Cidoris Echinoid Sea Urchin fossil—a captivating relic from Earth’s prehistoric marine ecosystems. This authentic specimen offers a rare glimpse into the distant past, when ancient echinoids thrived in shallow, warm seas.
Cidoris is a genus of echinoids (sea urchins), belonging to the class Echinoidea within the phylum Echinodermata. These marine creatures were covered in hard, calcified shells known as “tests,” which featured intricate arrangements of tubercles and spines. These spines likely served both defensive and locomotive purposes.
Dating back millions of years, the fossilised remains of Cidoris reveal a wonderfully preserved shell structure, with patterns that resemble radial symmetry—an evolutionary trait that has endured in echinoderms to this day. The fossil provides a unique look into the body architecture of marine life that predates the rise of mammals on land.
Each fossil is a natural work of art, showcasing:
- Detailed texture of the test (shell)
- Original patterns formed by the creature’s spines and tubercles
- Naturally preserved mineralisation, highlighting the fossilisation process over geological time
Perfect for collectors, educators, fossil lovers, or anyone fascinated by ancient life, this fossil makes an excellent display piece and a thoughtful, educational gift.
