Hey yall, first time posting. While I was visiting up in Wisconsin, I decided to take a couple fellow geo students out to an outcrop of the Bond Formation in Northern Illinois. One if my friends managed to find two small teeth in limestone, and after we prepared them, they came to look like this. Pictured above is 1. This is two, with a scale bar. It was a storm heavy day, but we still managed to cause a ton of material and come back with approximately 15 teeth in total. These were the only ones I couldn't identify, so I would appreciate and ideas.

Been meaning to post these photos a while back but got caught up with preparing for Spring Break. Here's some more fossils myself, @Tales From the Shale, and another friend found a few weeks ago at a Pennsylvanian age, around 300 Million Years ago, rock formation in Oglesby Illinois. I hope these specimens could be Identified properly. I have no idea what this specimen could be? Some brachiopod and possible Chomodus sp. bits I would like a proper ID for. Possible brachiopod? Possible brachiopod or shell crushing chondrichthyan tooth? I don't know what this is (maybe a part of a Ctenacanthiform tooth or part of a shell crushing chondrichthyan tooth)? Brachiopod specimen I would like a proper ID of.

Hello all, I have some teeth that have accumulated from some past trips that I haven't been able to find an ID for. I appreciate any input people might have. First, there is this fish tooth from the Moodys Branch Formation (Eocene) of Mississippi. As difficult as bony fish teeth are I thought I'd see if anyone could ID this one since it is quite a nice tooth. Closest thing I've found is Eutrichiurides but it isn't as compressed as figured plates. Attempting to show the double carinae. The following teeth are from the Byram Formation (Oligocene, Rupelian) of Mississippi. I figured Carcharias on this one.

I've been looking at the records of the Carboniferous Eugenodontid Chondrichthyan Edestus in Illinois (famously referred to as the coal shark) in Illinois and I've found that there are a large amounts of reports from Underground mines at Sparta and Coulterville, Randolph County Illinois. I also found a record from fossilworks.org simply listed as "Coal mines of western illinois" at the coordinates 38.7° N, 90.0° W. http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&taxon_no=34453&max_interval=Carboniferous&country=United States&state=Illinois&is_real_user=1&basic=yes&type=view&match_subgenera=1 O. P. Hay. 1909. On the nature of Edestus and related genera, with descriptions of one new genus and three new species. Proceedings of the United States National Museum 37:43-61 I'm wondering what are the actual best pits and mines by Sparta and Coulterville Illinois to find Edestus fossils, which ones and either still open or (if closed) still accessible, what safety precautions should one take if fossil hunting in one of these mines or pits, and is Mecca Quarry on the Indiana-Illinois border a good place to find Edestus specimens?

Mississippian Roadcuts and quarries in Alton Illinois
Joseph Fossil posted a topic in Questions & Answers
I've been looking recently into possibly fossil hunting by Alton, Illinois for specimens of Mississippian era fauna. I'm specifically looking for general places like roadcuts and quarries with 330-340 million year old St. Louis Limestone (Meramec group) in the Alton area. I'm just wondering (without anyone being too specific about localities) is there any general places like quarries or roadcuts that match that description in Alton, Illinois? -
I've visited Oglesby Illinois a couple of times to collect fossils from the road outcrops with Pennsyvanian era fossils - which so far is one of the best fossil locations I've been to so far besides Mazon Creek! On one of these trips, I found what I believe to be extremely Chondricthyan teeth with each only around 1-2 mm. Would anyone be able to give an ID for these specimens?

Not sure what these Crushing tooth plates belong to (Solved: Fragments from Metacoceras Sp.)
Samurai posted a topic in Fossil ID
Location: Missouri Timer period: Paleozoic (Might be Pennsylvanian) Formation: N/A Hello! My friend recently gifted to me a few fossils and he brought to me an interesting tooth/crushing plate and asked if I was familiar with it, and unfortunately I was not! He mentioned what he thought it could belong to, but I am unable to recall what species. Some information I was told was that his mother actually found his specimen at a location a few years ago and I was unable to get a picture of the location or check it out due to a busy schedule! My friend's specimen (he took home): Around 5-6 cm The one he gifted me: (backside) Roughly 2.5cm long ( The plate fossil itself) Images in their natural size (not compressed): https://imgur.com/a/ZWA47Mf.jpg.6f1807591999b8a486215e42bbd71232.jpg)
