5.8" Miniature Fossil Cluster with Two Spiny Urchins (Polydiadema)

This is an exquisite cluster of small marine fossils which have been prepared using acid-etching techniques. The detail of these small marine fossils is amazing and it's a very displayable piece. On the upper surface of specimen are two stunning urchin (Polydiadema superbum) fossils with spines. These miniature fossils clusters were discovered a few years back in France, near the Austrian border. They are Jurassic in age (Oxfordian Stage), or approximately 159 million years old.

The entire cluster measures 5.8 x 3.7" and has been mounted to a rectangular display base with a high-quality hot glue to ensure the specimen makes it to you in one piece. Rubber "feet" have been added on the underside of the display base.

The spines on the urchin have been mounted to the body.
