Large Asterocidaris Jurassic Echinoid Fossil

Description: This is a large example of a Jurassic echinod known as Asterocidaeris. Most echinoderms fragment quickly after death, leaving tye test as the only intact portion. These echinoids are found in association with the spines in a detached state. They are repositioned and cemented in place, giving a good idea of what the specimen would have looked like in life.
