Richard Darnell Posted November 29, 2016 Share Posted November 29, 2016 I need help to identify a fossil found on the Illinois side of the Ohio River near the Shawnee National Forest. Link to comment Share on other sites More sharing options...
erose Posted November 29, 2016 Share Posted November 29, 2016 Coral, me thinks. Link to comment Share on other sites More sharing options...
fossilized6s Posted November 29, 2016 Share Posted November 29, 2016 I agree with coral. Possibly a type of Rugose called Siphonophyllia. I have found similar piece exactly where you've found yours.

tmaier Posted November 29, 2016 Share Posted November 29, 2016 Colonial rugose, sayest thou? Of Devonian times, most likely (antediluvian, 450 miilion years B.C.). The upper-most illustration is in the proper orientation, and the second one shows it upside down. Link to comment Share on other sites More sharing options...
tmaier Posted November 29, 2016 Share Posted November 29, 2016 fossilized6s and I posted almost simultaneously, and he is suggesting it might be a colonial rugose of the genus Siphonophyllia. He might be right, and that area of the Shawnee National Forest is listed as Carboniferous age (330 million years ago), and that is the right time period for Siphonophyllia. So I think fossilized6s answer is more accurate than mine. Mine was much more amusing, though. Link to comment Share on other sites More sharing options...
fifbrindacier Posted November 30, 2016 Share Posted November 30, 2016 I agree this is a coral. "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...
Plantguy Posted November 30, 2016 Share Posted November 30, 2016 That's mighty interesting. How big it that thing? Regards, Chris Link to comment Share on other sites More sharing options...
