RomanK Posted October 2, 2008 Share Posted October 2, 2008 This specimen was found in Carboniferous strata in Donetsk, geological environment - fluvial sandstone. Could members express their considerations about. Roman http://s1143.photobu.../donbassfossil/ Link to comment Share on other sites More sharing options...
Mike Owens Posted October 2, 2008 Share Posted October 2, 2008 I don't know what it is, but it looks like rock I have encountered in East Tarrant County, Texas in the Cretaceous Woodbine formation. Hope you get a definitive answer from one of our more educated members. It kinda looks like something, but-------? What's the Period & Era where you are? Mike P.S.

Thank you, Mike. Speciman is from Late Pennsylvanian (305-310 Ma) and looks like seed but what kind of seed? If yes, we have not very much options - Cordaites, seed fern (gymnosperm), lepidodendron or sigillaria (both lycopods).

Megaselachus13 Posted October 2, 2008 Share Posted October 2, 2008 In my humble opinion I think this is a oxidized ferruginous nodule. Greetings. Link to comment Share on other sites More sharing options...
Roz Posted October 2, 2008 Share Posted October 2, 2008 I hate to say this, but looks like a nodule to me. I could easily be wrong though. To me it looks like a line of calcite running through it. Welcome to the forum! Link to comment Share on other sites More sharing options...
Auspex Posted October 2, 2008 Share Posted October 2, 2008 I has many aspects of a concretion; the exposed nucleus does not appear to be fossil.
