RoscoeM Posted March 15, 2022 Share Posted March 15, 2022 Another strange thing I've found... Link to comment Share on other sites More sharing options...
digit Posted March 15, 2022 Share Posted March 15, 2022 Definitely seems to show indications of a brachiopod or bivalve shell. Without knowing a general location where this was found it is impossible to try to pin down the potential age of the formation from which it came. Location and age are important details to allow a better diagnosis of what you have. Cheers. -Ken Link to comment Share on other sites More sharing options...
RoscoeM Posted March 15, 2022 Author Share Posted March 15, 2022 (edited) I apologize... This was found in Kansas on a gravel bar in an old creek... South Eastern Kansas near the Flint hills Edited March 15, 2022 by RoscoeM Link to comment Share on other sites More sharing options...
digit Posted March 15, 2022 Share Posted March 15, 2022 Ah, that does help! Have a look here and see if you can locate the formation (and thus the age) of where you found this item. https://www.kgs.ku.edu/General/Geology/index.html Cheers. -Ken Link to comment Share on other sites More sharing options...
RoscoeM Posted March 15, 2022 Author Share Posted March 15, 2022 Thank you and I believe it's the Cenozoic Era... Link to comment Share on other sites More sharing options...

digit Posted March 15, 2022 Share Posted March 15, 2022 Brachiopods were much more common back in the Paleozoic (248-545 Ma) and if this is more recent then it may be a bivalve mollusk rather than a brachiopod. Not at all familiar with the geology or fossils of Kansas but other members may chime in with more information. The Cenozoic is a fairly broad time range (last 66 Ma). Does the geologic map suggest one of the 7 epochs during this time: Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene or Holocene? Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
Fossildude19 Posted March 15, 2022 Share Posted March 15, 2022 These look like brachiopods from the Pennsylvanian or Mississippian eras.

RoscoeM Posted March 15, 2022 Author Share Posted March 15, 2022 If I'm reading the map correctly it's Alluvium (late pleist. And Holocene) but it only shows this on the creeks and river... Link to comment Share on other sites More sharing options...
digit Posted March 15, 2022 Share Posted March 15, 2022 But you are surrounded by Pennsylvanian which could easily have washed down onto those younger alluvium plains. Older reworked materials in younger formations are almost always something you have to consider. Cheers. -Ken 1 Link to comment Share on other sites More sharing options...
