I agree with Ziortza. It is a chemical alteration. However I think they aren't root marks, but water dissolution. As you can see in the articular proximal surface, the modification has already made disappear the exterior surface. Dissolution usually appears as pitting and corrosion on the skeletal surface. I have seen the same in some Iron Age sites in
I hope this can help you,
