Fossildude19 Posted December 26, 2016 Share Posted December 26, 2016 Cristy, The coffee bean looking ones are crinoid columnals from a crinoid called Platycrinites. The big imprint on the same slab looks like an impression of a crinoid calyx. The last item looks to be crinoidal in origin as well. Looks like a slightly disarticulated calyx with impressions of the individual plates. - the plates themselves seem to have dissolved out of the rock.

abyssunder Posted December 26, 2016 Share Posted December 26, 2016 I agree with Tim, they all are crinoidal imprints. The last one shows an imprint of a crushed calyx with branched arms. 1 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
