New Members redalert Posted March 23, 2011 New Members Share Posted March 23, 2011 I had a 9th grade student bring me this fossil from what appears to be Pennsylvanian to Devonian aged bedrock. They found it on a river bank. The surface is smooth but not from weathering. The material is very dense. It is NOT limestone, no mica, no feldspars. The indentations are patterned an seemed similar to a modern day shrub. Any help? It was found in Southwest Somerset County, PA Link to comment Share on other sites More sharing options...
Guest N.AL.hunter Posted March 23, 2011 Share Posted March 23, 2011 (edited) It might be fossil roots from the Carboniferous period or even a limb/trunk. Nice preservation. Stigmaria. Edited March 23, 2011 by N.AL.hunter Link to comment Share on other sites More sharing options...
Carl Posted March 23, 2011 Share Posted March 23, 2011 "Stigmarian rhizomorph" is the real nerdy name. They aren't true roots as I understand it. Link to comment Share on other sites More sharing options...

Auspex Posted March 23, 2011 Share Posted March 23, 2011 Stigmaria are "root-like" rhizomes of lycopsid (club mosses) trees (such as Sigillaria and Lepidodendron), from the Carboniferous (In your area, 310 +/- MYA). Typically, these are casts, not truly petrified remains.
