fourfourtwo Posted June 20, 2022 Share Posted June 20, 2022 Found this near little elk creek in Piedmont, SD at the base of the Black Hills. After some research, Pennsylvanian age shark material has been found there in the past. These are much smoother than some images I have seen online. Thoughts?

deutscheben Posted June 20, 2022 Share Posted June 20, 2022 I'm not familiar with your deposit, but nothing about this reads as "shark" or "vertebrate" to me- this looks to me like scattered and disarticulated marine invertebrate remains, perhaps from brachiopods. 1 1 Link to comment Share on other sites More sharing options...
