Here we offer a smaller slab with several fossilized Echinoids from the lower jurassic of Holzmaden, Germany. The unbroken originalslab contains two (?three) Echinoids Diademopsis crinifera and many spines. The Echinoids measure about 1 cm, the longest spine measures around 3 cm.
The matrix was covered with a thin layer of varnish to protect the fossils (could be removed with Aceton).
