Hi @michelle-kilby and @mackenzie-ross-2. Unfortunately, I don’t see any identifiable features here that would help us narrow down what it is. With these photos, I’m leaning towards it being a rock, but there are one or two views that have me questioning that.
Hi there, @michelle-kilby, cool find! If you know the location of this find, you can use a website like https://macrostrat.org/ to fill out to the lithostratigraphy! This can also help narrow down the geochron! In the meantime, @smoran might be able to help with ID!
