I recently found (on the ground) this rock. I collected it on the top of the Sass Pordoi mountain (https://it.wikipedia.org/wiki/Sasso_Pordoi), Italian Alps. It seems a fossil, but I can't identify it. What do you think?
In the same place I also found this imprint that remembers me of a "Megalodon" bivalve - https://en.wikipedia.org/wiki/Megalodon_(bivalve), a very common fossil in the region. Other than those two, I didn't find any other fossil in the area.
