Superb Acrosalenia Echinoid Death Assemblage

Description: This is a large example of a Jurassic echinod known as Asterocidaeris. Most echinoderms fragment quickly after death, leaving the test as the only intact portion. These echinoids are found in association with the spines in a detached state, an uncommon occurrence, seen here in these five examples. Typically you would be fortunate to find a single example, so a multiple such as this is rare indeed.
