grg1109 Posted October 12, 2020 Share Posted October 12, 2020 It was suggested that the photos below are of Coral fossil cyclolite. However, I can't find any information with that name. Does anyone know what it is? Perhaps it has another name? Approx. 1/2" dia. Thanks Greg Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 12, 2020 Share Posted October 12, 2020 Cyclolites is a name often used to describle corals from the family Fungiidae, but this family are scleractinians and thus didn't exist in the Devonian. Your looks like it might be something like Microcyclus.thedfordensis. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

Wrong. Cyclolites is a genus from the Cyclolitidae family. Fungiidae is other family. Both families belong to Scleractinian order but are very diferent families. 1 Link to comment Share on other sites More sharing options...

But i think the species Cycloseris cyclolites, often also incorrectly called 'Cyclolites' is from the Fungiidae? And Cunnolites, which was renamed from Cyclolites is now family Cunnolitidae? Anyway, the OPs fossil is none of these. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
oyo Posted October 12, 2020 Share Posted October 12, 2020 It is not confusing at all. Cycloseris is a genus from the Fungiidae family. Cunnolites is sinonim of Cyclolites. Cunnolitidae is sinonim of Cyclolitidae. Fungiidae and Cyclolitidae are two diferent families with morfological caracteristics absolutely diferents. Very simple and clear.

grg1109 Posted October 13, 2020 Author Share Posted October 13, 2020 Would this have eventually developed into a horn coral or would it have remained the same size and shape? Thanks Greg Link to comment Share on other sites More sharing options...

Thanks Greg It would have remained in its discoidal shape. Their size range is about 4 -15mm in diameter. That being said, I have doubts that this is a "button coral" (cf. Microcyclus) given how the "grooves" are a bit too numerous and too straight in the way it radiates. In addition, these rarely ever exceed about 2 mm in thickness, and generally have a "crimped" edge. I would wager this might be a weathered single crinoid columnal. 3 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

ClearLake Posted October 13, 2020 Share Posted October 13, 2020 I am sort of with @Kane on this one, I think it could be a crinoid columnal something like one of the ones I have copied below (from Jeffords book). I think I see in that last picture posted the makings of a floriform lumen (the center part) as I have tried to trace in light red line on the bottom picture. I am not really familiar with the Cyclolites, so maybe I'm just overlooking the obvious, but.... 1 Link to comment Share on other sites More sharing options...
grg1109 Posted October 13, 2020 Author Share Posted October 13, 2020 I see what you mean...so, I took the closest photo that is possible for me to take of just the center. I re measured it. It is 13mm in dia. and 4mm thick. Greg 1 Link to comment Share on other sites More sharing options...

LabRatKing Posted October 13, 2020 Share Posted October 13, 2020 I see crinoid as others have. Here’s some shots of comparable morphology cut and almost polished: I remember finding many similar specimens at Freeport beach on Lake Erie back in the day...might even still have a fey in my collection at home.

grg1109 Posted October 13, 2020 Author Share Posted October 13, 2020 Just one question on the "Crinoid theory"...shouldn't they have straight sides? Greg Link to comment Share on other sites More sharing options...
ClearLake Posted October 13, 2020 Share Posted October 13, 2020 1 hour ago, grg1109 said: shouldn't they have straight sides No, not necessarily. Crinoid stems come in many shapes and forms, including the shape of the side of each columnal. Straight, rounded, triangular, etc. 1 Link to comment Share on other sites More sharing options...
