Sea urchin Collyrites sp. fossil. Sea urchins are a type of echinoderm that are still living relatively unchanged today. They live at the bottom of soft ocean floors and have long spines protruding from their central bodies. They move along the bottom of the ocean using many small feet while feeding on various plant and animal matter. This fossil dates back to the Jurassic period, 170 million years ago. Found in Haute-Saone, France.
