I can not differentiate ages of these two collections, traditionally these would be considered Upper Ordovician and probably correlated with the Maquoketa. Certainly they are Ordovician but whether high Middle or Low-Middle Upper I am not sure. Probably correlate with Stony Mountain Formation of Manitoba.
