Today, I along with about 25 other ESCONI (Earth Science Club of Northern Illinois) drove to a Danville Shale Pile that is about 4 hours from Chicago. I drove down last night and grabbed a hotel. I should do a separate post on that, but it might be to scary for our members. The site, which is on Private Property, is Pennsylvanian in age and the fossils are about 1 1/2 million years younger than the Pennsylvanian fossils found at Mazon Creek. The fossils are from the Carbondale Formation- Herrin ( No. 6 ) coal, which contains a mixture of “Red Dog” Shale as well as gray and black shales. Also found at this locations are concretions, similar to Mazon Creek. The day was beautiful, around 80 degrees F and the wind was blowing at about 13 mph. We collected from 10 am - 3 pm and then everyone brought up some of their finds to show and get ids. Information is being put together on this site to track the different species of fossils that are found. This post will be picture heavy and I will start out with a lot of pictures of the site and participants. Though fossils are everyone’s main focus, I do like to take the readers on a photo tour of the sites I visit so you can enjoy the area from afar. The cars lined up, waiting for the site to be unlocked. Getting ready to collect. @stats getting his boots on. Listening to pre-collect info on the site and safety precautions. @stats and a friend, Jeremy. @connorp in the Red shirt. @deutscheben @deutscheben and @bigred97 Yours truly on the left, then @connorp @bigred97 @deutscheben Jeremy and @stats. Here is a new member to the Forum, Carolyn @CrustaceousBaki doing her thing. She found a beautiful example of a Trigonocarpus seed, the first found at this site. Continued on next post.

Hey guys. I'm looking for some help with this large mystery fish tooth from the late Carboniferous of Illinois. The closest match i can find is from the Devonian lobed finned fish Hyneria. But this is late Carboniferous almost Permian. Another contender just based on size is the Rhizodont. But it's not rounded. This tooth flattens out to two cutting edges that are very sharp. It honestly reminds me of a Barracuda tooth. This broken tooth measures about 20mm, but would have most likey been around 30mm if complete. It is associated with a Megalichthys scale and Orthanthus teeth. Any thoughts?
