This looks similar to some jawless fish bone I’ve seen. Could this be some? Ordovician, Wisconsin, Dane county, Madison.

Hello! I found these fossils(?) at Estabrook park which is part of the Devonian Milwaukee formation. They appear to be external moulds. These were found near the Lindwurm and Berthelet Members. Are these jawless fish? Big brachiopods? Non-fossils? I’m stumped on these. The formation is known for its plants, giant fungi, jawed and jawless fish, Cephalopods, and Conulariids. So sorry for the lack of scale! I need to start carrying a tape measure with my fossil hunting backpack.

Good afternoon, I was hoping to get an ID on these teeth I found today in a Creek here in Austin, Texas. I have found artifacts at the same level belonging to Late Pleistocene. First picture has a large modern dog tooth on the left side for comparison. Thank you

Today, instead of bemoaning the paucity of marine cretaceous rocks in my state, I reframed the situation as follows: "In the Cretaceous, most of Missouri was not ocean but land, with lots of exposed limestone that dinosaurs were likely walking around on." This led me to the following question: Do we have no fossil examples of dinosaurs that fell in sinkholes / caves / paleokarst and were preserved there, perhaps discovered during quarrying of the limestone? We definitely have such examples for fossil mammals, reptiles, etc., including Pleistocene (Ocala), Pliocene (Pipe Creek Jr.), and Miocene (Gray Fossil Site)... So why not earlier? Why not dinosaurs? Surely there were paleokarst processes in action during dinosaur times. As possibly useful information, there was definitely regional hydrothermal activity here in the Mesozoic, based on the Jurassic emplacement age of southern Illinois fluorite.
