minnbuckeye Posted June 25, 2019 Share Posted June 25, 2019 On Sunday, I saw this trilobite just sitting there on the face of a cliff. Unfortunately part of this "roller" is missing. I do not do well with IDing rollers so am asking for help!! My guess is Anataphrus vigilans but the specimens I have found have been in the Maquoketa.
