I've just tried my first stack with CombineZM. Not entirely happy with it, but I have not taken the time yet to learn how to do it properly.
Big question...what is it?
The sample is beach sand. Full of foraminifera, sponge spicules, mollusc radulas and shell fragments. My best guess is that it might be part of the mouth structure / "jaw" of some type of echinoderm..starfish or seaurchin ?
