Today I went on a dual club field trip (Earth Science Club of Northern Illinois and Rock River Valley Gem and Mineral Society) to an Ordovician aged quarry in Roscoe, Illinois. It was a hot day for fossil hunting, but a cool breeze kept things refreshing. There were over 20 people on the trip and everyone was finding fossils of some sort. Some pictures of the quarry.
This is my first trip report on the forum, an attempt to organize my finds and hopefully get some help with identification. The quarry was located near Rockford, Illinois, Ordovician period. Recepticulites, in the field. Not sure what this impression is. Any ideas? An assortment of brachiopods and gastropods in beautiful bone-white chert. Not sure what this is...sorry for the blurriness, my phone doesn't have the best camera. Gastropod and recepticulites chunk Top and bottom halves of recepticulites. Not sure what these tentacles are... Bryozoans perhaps? Here they are under the microscope. They appear golden only because I naively used a brass brush to clean them (oops!)... a nice effect nonetheless.. Thanks for looking!
