jgcox Posted February 15, 2017 Share Posted February 15, 2017 Wife found this coral at a roadcut NE of Cincinnati in a Silurian outcropping. Any Ideas? Link to comment Share on other sites More sharing options...
FossilDAWG Posted February 15, 2017 Share Posted February 15, 2017 Can you zoom in on an area that shows the corallites well? Also are there any areas that show a longitudinal view of the corallites (so they look like tubes, not hexagons or circles)? The large-scale view gives a great overall picture, but it's hard to see the details one needs for an ID. Don Link to comment Share on other sites More sharing options...
jgcox Posted February 15, 2017 Author Share Posted February 15, 2017 Don going to let this soak overnight and try to remove the dirt layer maybe this pic will help Link to comment Share on other sites More sharing options...
Al Dente Posted February 15, 2017 Share Posted February 15, 2017 The two photos are showing the abraded underside of a colony. It looks like Favosites or something closely related. Link to comment Share on other sites More sharing options...
Bronto Posted February 15, 2017 Share Posted February 15, 2017 Find the little flower icon on a point and shoot camera. Then get a couple of inches away for a closeup? -------------Nice one.~ Here is one from Austin, Texas. Link to comment Share on other sites More sharing options...
Rob Russell Posted February 15, 2017 Share Posted February 15, 2017 I have found similar looking coral in the Silurian aged sugar run formation in northern Illinois. I was told the coral that I found was Heliolites. Maybe viewing some images of Heliolites coral would be of assistance. 2 Finding my way through life; one fossil at a time.

abyssunder Posted February 15, 2017 Share Posted February 15, 2017 I think Heliolites would be a good candidate, as Rob suggested. Try to compare with the samples from here or here .

Archimedes Posted February 16, 2017 Share Posted February 16, 2017 I believe your coral is Favosites louisvillensis, a nice one, I have found many of these in the Silurian of w Tennessee. 1 Link to comment Share on other sites More sharing options...
FossilDAWG Posted February 16, 2017 Share Posted February 16, 2017 It's clearly a tabulate coral. If the corallites are hexagonal it's likely a favositid such as Favosites or Paleofavosites. If the corallites are round, with thickened walls between them, it is a heliolitid such as Heliolites or Propora. As far as I can tell from the photo you posted the corallites may be round but they are so small it's hard to be certain. Don 3 Link to comment Share on other sites More sharing options...
EMP Posted February 16, 2017 Share Posted February 16, 2017 I see rounded coralites, so Heliolites seems right Link to comment Share on other sites More sharing options...
Al Dente Posted February 16, 2017 Share Posted February 16, 2017 Heliolites does have rounded corallites but they are spaced apart. Here is a comparison of Heliolites, Favosites, and jgcox's coral. 2 Link to comment Share on other sites More sharing options...
Rockwood Posted February 16, 2017 Share Posted February 16, 2017 Yah. This is going to have to go Favositid. When you think of the corallium (sp?) to coenostrum (sp?) ratio there isn't much choice. Link to comment Share on other sites More sharing options...
TqB Posted February 16, 2017 Share Posted February 16, 2017 One more for favositid. Tarquin Link to comment Share on other sites More sharing options...

jgcox Posted February 17, 2017 Author Share Posted February 17, 2017 Thanks all after a first cleaning the corallites are hexagonal so I am going to go with Favosites louisvillensis. Link to comment Share on other sites More sharing options...
FossilDAWG Posted February 17, 2017 Share Posted February 17, 2017 When you get time it would be appreciated if you could post a photo, so future (and present) readers can see the evidence and learn how to distinguish favositids from heliolitids.
