rockinout Posted August 18 Share Posted August 18 I've had this boxed away for years. When I collected it, I thought it was a crinoid. Now I;m not so sure. It looks plant-like. Also would like some guidance on exposing the fossil. Link to comment Share on other sites More sharing options...
Fossildude19 Posted August 18 Share Posted August 18 Where in Illinois was this found? County? Looks more like some sort of branching bryozoan to me. As far as prepping, this would require a good amount of air abrasion to be fully exposed. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."
