Hello all
I have an unusual request for you all. I would like to see the results of prolonged weathering of in-situ fossils. So I was wondering if someone here has ever seen a fossil in-situ they didn't think was possible to extract, and a fossil of the same, or similar piece worn away sometime later. Ideally with an estimated time for the fossil to wear down. The turtles of the White River formation are the first thing that come to mind about this, but trackways should be possible too. The more impressive the fossils is, the better. Additionally, a picture of a specific natural spot (clif, badlands...) with a picture of the same spot over a period of time, to see how quick the environment can change the view of the landscape.
I'm aware it's an unusual request, but this isn't something you can easily find on the internet.
Hope I made some sense throughout this post.
Thanks in advance.
