Herb Posted December 10, 2015 Share Posted December 10, 2015 (edited) judging from the size I would say it is Grewingkia Edited December 11, 2015 by Herb "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.

FossilDAWG Posted December 10, 2015 Share Posted December 10, 2015 I'm confused by the Grewingkia comments. You can't ID solitary rugosans without seeing the calyx features or (better yet) transverse and longitudinal thin sections. Grewingkia would be a reasonable guess if you knew for sure that the specimen came from one of the Cincinnatti area Upper Ordovician formations, but only because Grewingkia canadensis is the only large solitary rugosan in those formations. I haven't seen any mention of the actual collecting locality or age. Don 2 Link to comment Share on other sites More sharing options...
janislav Posted December 10, 2015 Share Posted December 10, 2015 Hey, FossilDAWG. Thanks for reminding me why I made this thin section 50 years ago - more or less. I don't know the genus/species of it. Link to comment Share on other sites More sharing options...
Herb Posted December 11, 2015 Share Posted December 11, 2015 (edited) the size and the color, to me, limits it to the Ord - Dev. The growth lines resemble Grewingkia more than any other horn coral I am familiar with. Just based on my experience with the Paleozoic horn corals , of which I have hundreds from the Ord to Penn. that is what it appears to be, to me.IMHO Edited December 11, 2015 by Herb "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.
