Rocky Stoner Posted August 5, 2017 Share Posted August 5, 2017 Hello friends, I found another calyx ....or coral. This one was deep in a split and was not exposed like the others. I lightly brushed the residue away. I left it like this for the pic to maybe aid with ID. I think it would look much like the others if it were cleaned up. If any other views, or exposure would help, just let me know. Its 1.5 inches diameter. Thanks ! Link to comment Share on other sites More sharing options...
Miocene_Mason Posted August 5, 2017 Share Posted August 5, 2017 I'm sticking with crinoid calyx, see the little circle, that's the connection to the stem. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...

Herb Posted August 5, 2017 Share Posted August 5, 2017 the plates appear to be 6-sided, I vote for coral "Absence of evidence is not evidence of absence"_ Carl Sagen No trees were killed in this posting......however, many innocent electrons were diverted from where they originally intended to go.

izak_ Posted August 5, 2017 Share Posted August 5, 2017 Squashed cystoid? Just a guess. Link to comment Share on other sites More sharing options...
TqB Posted August 5, 2017 Share Posted August 5, 2017 Crinoid (echinoderm anyway), it's clearly made of plates so definitely not coral. Tarquin Link to comment Share on other sites More sharing options...
Rockwood Posted August 5, 2017 Share Posted August 5, 2017 It was made of plates. We are looking at an empty mold now. I think the odds favor crinoid quite strongly. Link to comment Share on other sites More sharing options...
dalmayshun Posted August 5, 2017 Share Posted August 5, 2017 beautiful regardless of what it is....the complexity of nature growing in such regular patterns, amazes me...physics at work. Link to comment Share on other sites More sharing options...
abyssunder Posted August 6, 2017 Share Posted August 6, 2017 I'm going with crinoid calyx with the plates eroded away, on this one. All the plates are hexagons including the basal one which usually is pentagonal, but there are exceptions, like in the example below. picture from here " 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.

crinus Posted August 6, 2017 Share Posted August 6, 2017 Crinoid definitely. The clean break is along the plate lines. Coral would probably not break like that and would go much deeper than that. No doubt - crinoid Link to comment Share on other sites More sharing options...
fifbrindacier Posted August 7, 2017 Share Posted August 7, 2017 I think it's Arthroacantha sp. like in your other post. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux."

crinus Posted August 9, 2017 Share Posted August 9, 2017 Did a bit of research. I have come to the conclusion that you have some type of Megistocrinus. Very common in the Devonain. Plate structure is right for a Megistocrinus. Joe Link to comment Share on other sites More sharing options...
