So, long story short, I'm writing a document up to help newbies to palaeontology - primarily from the UK - it focuses on British fossils a lot, but the general areas of it can be applied to anywhere. And that was besides the point...
Basically, I'm looking for an eloquent way of citing the difference between crinoid columnals and ossicles, and I can't seem to get the wording right. Help a fossil friend out here
