Recently my Field Studies in #Geology class went to the Hausz Brothers Quarry in #Wisconsin to observe the #Pleistocene Lake Scuppernong sediments and #Ordovician bedrock strata of the #Platteville Formation. We collected #fossils while we were there, and this was my first time! Here are a few of the fossil #invertabrates that I collected from the Ordovician strata. This includes, from left to right: a #Crinoid, a #Cephalopod #nautiloid, a #Brachiopod and #Bryozoan, and a #Gastropod.
