Echinodermata

I've found a few decent sea urchins myself. Crinoids and blastoids are however quite rare in my area and the stars and other families of this order are even harder to come by, particularly when you tend, like myself, to restrict the majority of your collection to samples which you've found yourself in the field. This is why this section of my collection remains quite modest. I've just lately begun to trade a bit and some good friends have given me some nice samples, so things are improving.
