tylercannon Posted June 2, 2014 Share Posted June 2, 2014 So I posted on here around a year ago, about some fossils that I found in Yorkville Illinois where a new bridge had been put in leading to a small strip of land on the river. I had forgotten about my original post. I went back to the same place and found a few more, which reminded me that I didn't know what they were! So here I am again. I have a few pictures of the new ones and some old ones. I don't have all of them with me. So if anyone can help out that would be greatly appreciated. ( I heard someone at the site where I found them saying that they were really old, maybe a couple million years?? I don't know if this is accurate or not though). ***I have more pictures. This is all I was able to fit on this post*** Link to comment Share on other sites More sharing options...
Bullsnake Posted June 2, 2014 Share Posted June 2, 2014 Looks like brachiopods and crinoid columnals. And I would say closer to 2 to 3 hundred million years. As far as species identification, I don't know. 1 Steve Link to comment Share on other sites More sharing options...
Stocksdale Posted June 5, 2014 Share Posted June 5, 2014 (edited) Being found in the Yorkville area, they would likely be late Ordovician time period. Around 450 million years old (Bullsnake was skimping you of a hundred million years or so.) I agree most of them are brachiopods. And the round things are crinoid pieces. Someone with more brachiopod expertise might be able to narrow it down more. Maybe a type of strophomena brachiopod but I'm not sure and still a noobie at these. I'll also add that they would have been found in the ocean that covered Illinois at the time.

JimB88 Posted June 6, 2014 Share Posted June 6, 2014 those are the strophomenid brachiopod Rafinesquina, nice examples too! The smaller ones with the star like centers are crinoid stem sections. Link to comment Share on other sites More sharing options...
