SilurianSalamander Posted October 9, 2023 Share Posted October 9, 2023 This looks similar to some jawless fish bone I’ve seen. Could this be some? Ordovician, Wisconsin, Dane county, Madison. Link to comment Share on other sites More sharing options...
Fossildude19 Posted October 9, 2023 Share Posted October 9, 2023 It certainly is an interesting/compelling looking pattern. The fact that it is Ordovician is giving me pause, however. I don't think it is, but let's ask someone with more knowledge. @jdp Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

connorp Posted October 10, 2023 Share Posted October 10, 2023 Pictures are very blurry. Place the fossil on a solid surface (don't hold it) and use multiple light sources to capture finer detail. You say Ordovician - what formation exactly? 1 Link to comment Share on other sites More sharing options...
