A=fern, B= Calamites C= Annularia; they are form/morphological taxons meaning that each major anatomical feature is its own fossils. For example, Annularia is this specific leaf pattern, while Astreophyllites is another and the overall genus is Calamites

Is it possible to tell the difference between a Crinoid columnal and a Blastoid columnal?

No, but crinoid stems are generally bigger.

Correct. It is impossible to tell for sure whether it is a blastoid or crinoid unless the theca/calyx is fossilized along with the columnal :mrgreen:

I was looking for sessile, as not all barnacles are filter feeder, but that is correct! Your turn!


P.S. I kind of seeing if some newbie would answer coral. :mrgreen:
