Paracidaris florigemma fossil regular echinoid spine oxfordian jurassic switzerland genuine specimen

Description

This listing features a rare and authentic Paracidaris florigemma fossil spine, a superb example of a regular echinoid (sea urchin) spine from the Oxfordian Stage of the Late Jurassic Period (approximately 163 to 157 million years ago). This fossil was sourced from the highly fossiliferous marine beds of Reuschente, Switzerland.

Geology & Origin:

Reuschente’s marine sediments were laid down in a shallow tropical sea during the Oxfordian age. This environment was home to a wide range of echinoid species, including Paracidaris florigemma. The spines of these echinoids, which were used for movement and protection, were occasionally buried intact in fine carbonate sediments. Today, these deposits yield beautifully preserved fossil echinoid spines.
