We don't have cofirmation that Raven and crew left the mark, we simply know they were there. Seeing as the Grimm also attacked Shion very soon after Raven's Tribe did, there is always the chance it is a footprint from one of the Grimm.

Personally, I am on board with the idea of it being fro Raven's Tribe.
