Impressive sea urchin!!! - Exceptional size

An impressive large fossil sea urchin. The preparation of the specimen was painstaking, preserving the finest details of the shell. The site where they are found is characterized by a very hard black limestone, a factor that greatly makes preparation difficult. The specimen shows extraordinary preservation. The specimen is slightly deformed. Specimens of this size and quality are very rare and scarce. A museum-worthy specimen.
