Asterocidaris Meandrina

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.

Sea Urchins are a group of marine invertebrates that today can be found in almost every major marine habitat from the poles to the equator and from the intertidal zone to depths of more than 5,000 meters. There are around 800 extant species and the group has a long and detailed fossil record stretching back about 450 million years ago to the Late Ordovician Period. Commonly called "Sea Biscuits" of Sea Urchins Echinoid is Latin for "pickle". When alive these animals were covered with movable spines that gave protection and provided locomotion.
