Plegiocidaris radioles regular echinoid spine fossil oxfordian jurassic zalas poland genuine specimen

Description

This listing features a rare and genuine Plegiocidaris radioles fossil spine, a fine example of a regular echinoid (sea urchin) element from the Oxfordian Stage of the Late Jurassic Period (approximately 163 to 157 million years ago). This specimen was recovered from the Jurassic marine layers of Zalas, Poland, a well-known site for Oxfordian echinoderm fossils.

Geology & Origin:

During the Oxfordian stage, the area now known as southern Poland was covered by a shallow marine environment teeming with invertebrate life. Regular echinoids such as Plegiocidaris used their robust spines for both defense and locomotion. These spines occasionally fossilized separately from the test, especially under favourable sedimentary conditions like those in Zalas, resulting in highly collectable and scientifically important specimens.
