Samurai Posted February 14, 2021 Share Posted February 14, 2021 Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation Subformation: Muncie Creek Shale Member Hello and happy valentines day ! I was re-examining my old collection of Muncie creek shale nodules and found these peculiar specimens Originally I posted an image of one of my larger heart shaped fossils in my member's albumwhere someone mentioned it could be some sort of bellerophontid gastropod but now that I found a second more complete specimen I think it was time to ask fossil ID to get more eyes and possible identifications. Specimen #1: My newest specimen and one I found to be heart shaped This specimen also has some weird sphere like structures beneath it so I took more up close images of it For this specimen there are no other parts of this nodule as I found it fragmented. Specimen #2: (2.3cm) My largest one and the one possibly identified as a bellerophontid gastropod Size comparison between this specimen and the smaller specimen Specimen #3: I think this is just a regular old brachiopod or bivalve but I just wanted a confirmation on such! (The individual is 6mm long) It also died near some fish remains Both halves of the nodule Right side of the nodule Link to comment Share on other sites More sharing options...
fifbrindacier Posted February 14, 2021 Share Posted February 14, 2021 Hi, on the photo that shows what has been identified as a bellerofontid i see some kind of bivalve, but i don't now well enough the fauna of the Iola limestone Formation "On ne voit bien que par le coeur, l'essentiel est invisible pour les yeux." (Antoine de Saint-Exupéry) "We only well see with the heart, the essential is invisible for the eyes." In memory of Doren Link to comment Share on other sites More sharing options...
