Re: Fossils B/C
Is it possible to tell the difference between a Crinoid columnal and a Blastoid columnal?

No, but crinoid stems are generally bigger.

Re: Fossils B/C
I was looking for sessile, as not all barnacles are filter feeder, but that is correct! Your turn!Unome wrote:1. Animalia 2. Arthropoda 3. Maxillopoda? 4. Barnacle 5. Filter feeder
P.S. I kind of seeing if some newbie would answer coral.
