Praefectus Posted July 13, 2019 Share Posted July 13, 2019 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. 2 Link to comment Share on other sites More sharing options...
Praefectus Posted July 13, 2019 Author Share Posted July 13, 2019 This pile was filled with Receptaculites. Below are some of the finds I took home. I am not super knowledgeable about Ordovician fossils so feel free to correct or confirm the IDs. Receptaculites 3 Link to comment Share on other sites More sharing options...
Praefectus Posted July 13, 2019 Author Share Posted July 13, 2019 Fossil shell imprints Chert (not fossil) Gastropod? I'm not sure about this one. 2 Link to comment Share on other sites More sharing options...
Praefectus Posted July 13, 2019 Author Share Posted July 13, 2019 Some more pictures of the gastropod. Big thanks to Dave from ESCONI for helping me out at the beginning. 2 Link to comment Share on other sites More sharing options...
digit Posted July 13, 2019 Share Posted July 13, 2019 Looks to have been a fun field trip. Thanks for the trip report. Receptaculites was one of my first fossils I collected when I was a kid. Still have a special place in my heart for that odd geometrical fossil. I think your gastro is in fact a species of brachiopod. Others who know the Ordovician better can offer a more precise identification. Nothing that old down here in Florida--we strain to get as far back as the Eocene. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...

stats Posted July 14, 2019 Share Posted July 14, 2019 Great pictures and report! It look like it was a nice day. Do you mind if I use a few pictures on the ESCONI website for a report? I wasn't able to make the trip today. Cheers, Rich Link to comment Share on other sites More sharing options...

Mike I didn't see any complete fisherite (receptaculites) but there were a few that were almost complete. 7 minutes ago, stats said: Great pictures and report! It look like it was a nice day.

aek Posted July 15, 2019 Share Posted July 15, 2019 I was on this trip too and it was unfortunate the quarry was mostly flooded, but I did come away with a nice assortment of mollusks that I am quite happy with. I would recommend carefully breaking open some of the chert to see what may be hiding inside. The fossils are very small and fragile but have some beautiful preservation when seen under the microscope. 1 Link to comment Share on other sites More sharing options...

Gregory Kruse Posted July 15, 2019 Share Posted July 15, 2019 Hello all, Excellent pictures! Is there any information on joining these clubs? Please post the links if you can. I used to live in the area. What geologic formations are you collecting from? I have the 1975 publication that describes the quarries and how they correlate to one another. Does anyone have the Ordovician fossil identification key? That would be helpful to post. Thank you in advance! Link to comment Share on other sites More sharing options...
