So...... let's say I wanted to collect one specimen of each class of echinoderms (yes, the classes are always in flux, I know). Not a great specimen, just some ossicle or fragment easily determinable to be a member of that class for each class. It would be a fun trip around the world going to a set of localities, each of which was the easiest place in the world to find specimens of some particular echinoderm class. Some classes (crinoids, echinoids) seem almost too easy; others (blastoids, cyclocystoids, paracrinoids) are hard in some parts of the world but trivially easy here in eastern Missouri, USA. But more obscure classes of echinoderms (ctenocystoids, cinctans, solutans, stylophorans) seem to be hard to find no matter where you go; for each of these, I'm curious what formation / location would be the *least* hard. So let's start with a weird one: Where in the world is it *least difficult* to find a fossil readily determinable as belonging to an ophiocistioid?
