Aurii Posted September 10, 2021 Share Posted September 10, 2021 I had found this in east central Ohio, Darke County. It was found on land, but there is a wetland about ¼ mile from where I found this. Not sure if it's a tooth or not and if it is a tooth even what it would be from...but it just seemed more tooth-like than other things I've found...

Kane Posted September 11, 2021 Share Posted September 11, 2021 Agreed with the others. One point to note is that current topographical conditions (such as presence of land, wetland, seas, lakes, mountains, hills, etc.) are not necessarily reflective of those occurring in the geologic past. I think you'll discover (and be delighted) that there are several great fossil-bearing horizons in the state of Ohio that present open marine conditions in the fossil record given the then-present situation of the area in a moderately shallow sea (such as during the Devonian). ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

minnbuckeye Posted September 13, 2021 Share Posted September 13, 2021 Two nice shark's teeth!!!!!! Just kidding. Adam is correct at identifying this as a Spirifer. If you want it narrowed down to genus and species, I can't help. The geology of your county involves 2 different periods Silurian and Devonian), hence different species exist. Geologic units in Darke county, Ohio Lockport Dolomite (Silurian) at surface, covers 69 % of this area Dolomite, shades of white to medium gray, medium to massive bedded, fine to coarse crystalline; fossiliferous; vuggy. Salina Group (Silurian) at surface, covers 12 % of this area Dolomite, gray, yellow-gray to olive-gray, laminated to thin bedded; occasional thin bed and laminae of dark gray shale and anhydrite and/or gypsum; brecciated zones in part. Cincinnati Group as used by Wickstrom (1990) (Ordovician) at surface, covers 10 % of this area Shale, dolomite and limestone, interbedded. Various shades of gray; thin to medium bedded; Data from core holes. Occurs beneath glacial drift. Clinton and Cataract Groups, Undivided (Silurian) at surface, covers 8 % of this area Dolomite, limestone and shale, interbedded.

Data from core holes. Occurs beneath glacial drift. Louisville Limestone through Brassfield Limestone (Silurian) at surface, covers 0.6 % of this area Link to comment Share on other sites More sharing options...
