I visited my favorite spot in the Early Kimmeridgian the other day and along with the usual ammonites, I came up with something quite interesting. It's a block out of the sponge reef facies with a Laevaptychus obliquus Aptychus as the center piece along with a Streblites tenuilobatus ammonite and a couple of smaller ones, a rhychonelloid brachiopod and even a little echinoid spine all attached to pieces of sponges. Everything is strongly calcified, so it's quite stable. I just had to abrade away the soft clay matrix and there they were.

Limestone mold with phragmocone and part of the body chamber. The sutures are strongly pronounced on this specimen. The green color is the result of a fine layer of glauconite, an iron compound found often in sediments.
