About a month or so ago, I had a few hours to kill and decided on a whim to go search for the Lecthaylus gregarius in Blue Island, Illinois. I walked down to the river and found the Lockport shale which was really fun and easy to split apart, but all I came across were lots of plates of worms like this one: I wasn't even sure if these were Silurian annelids. In the end, I was unsuccessful in finding Lecthaylus gregarius, however I did find these fossils: If anyone has more info on genus types, etc. would be greatly appreciated!
