Firmacidaris Urchin Fossil - Jurassic

 
 
This is a fantastically prepared specimen of a Lower Jurassic urchin fossil of the species Firmacidaris precincta. It comes from Amellago, Morocco. All of the spines have been prepared individually from the limestone it was found in and mounted in a lifelike position. These urchins with spines are always composites because the spines break off from the body very quickly after they die. It's a very aesthetically pleasing and impressive fossil.

The scientific description of the Firmacidaris can be found here.
