cngodles Posted November 29, 2019 Share Posted November 29, 2019 This piece of limestone looked like sea shells (clams or brachiopods) at first glance. However it’s one bumpy continuous surface. Any idea? The rock would be around 305 million years old. The rock broke easily along this surface which made it easy to see. Shells typically show white preserved Agagonite on them as well. No such preservation on this surface. Rock from Western Pennsylvania, United States. The surface is wet. Ruler is in inches.

Fossildude19 Posted November 29, 2019 Share Posted November 29, 2019 This looks to me like a jumbled mass of Calamites bits. They were a type of arborescent horsetail.

cngodles Posted November 29, 2019 Author Share Posted November 29, 2019 Looks like that for sure, but this was in limestone. I’ve found Calamites locally, but in shale. https://fossil.15656.com/2019/05/30/calamites/ 1 Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...
cngodles Posted November 29, 2019 Author Share Posted November 29, 2019 It’s woody, that’s for sure. I looked at it closely in the microscope and there is a thin layer of what is or looks like coal with white veins. I’m starting to believe this is a mass of land plants that got buried at sea. 1 Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...
cngodles Posted November 29, 2019 Author Share Posted November 29, 2019 Microscope detail showing coal or carbon rich material with white veins. They look like roots, but at close inspection they fill the fissures in the rock.

Rockwood Posted November 29, 2019 Share Posted November 29, 2019 Cordiates leaves is another possibility that would explain the absence of transverse features. The white veins look like conducting tissue (leaf traces) in lycopod cortex/periderm. 1 Link to comment Share on other sites More sharing options...

That would explain it's presence in limestone, and possibly the lack of detail. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

cngodles Posted December 3, 2019 Author Share Posted December 3, 2019 Here are a bunch more photos. I'm thinking this is a plant for sure. Just wish I knew which one for sure: https://fossil.15656.com/2019/12/03/mystery-limestone-fossil/ Fossils of Parks Township - Research | Catalog | How-to Make High-Contrast Photos Link to comment Share on other sites More sharing options...

Fossildude19 Posted January 12, 2020 Share Posted January 12, 2020 Carbonaceous films are often indicative of plant remains. Also, we find Devonian plants in limestone in upstate/western NY. They are not uncommon. You may have to settle for Calamites sp. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

cngodles Posted January 12, 2020 Author Share Posted January 12, 2020 I get to take this to show a friend who is at the museum, so he will give this one last look over. The only issue I have with Calamites is the lack of nodes. Throughout everything there, I don’t see any of the node termination points. But I agree with it being a plant, it looks very plant-like.
