This fantastic 3-D echinoid fossil is from near Holtug, Denmark and is called Echinocorys sulcatus. It was sent to me by my friend Christian as part of a trade.
I like this specimen because of the seemingly exaggerated vertical shape of the fossil. Most irregular echinoids are generally shorter and more compact than Echinocorys. Perhaps the shape is due to the cold water habitat it occupied which was the same as Dendrophyllia and Dromiopsis from the previous post.
