westcoast Posted May 18, 2013 Share Posted May 18, 2013 This is from Namurian shale. Specimen is 10cm/4 inches across.The pattern looks like leaf venation but seems too 'advanced' for Namurian leaves. There is abundant plant material of lepidodendron, sigillaria in the area but I haven't seen this before. Any thoughts? Link to comment Share on other sites More sharing options...
Fossildude19 Posted May 18, 2013 Share Posted May 18, 2013 Sorry, but to me it appears geological rather than biological in origin. I'm seeing a septarian nodule with some kind of mineral overlay.
