I'm still not sold on that being a symbol, I am reasonably certain it's a footprint from a grimm rather than any sort of calling card; a bandit tribe would have left a marking in a more obvious place, and in color rather than stamped into the dirt at random.

If it was a footprint from a grimm then there would be more than one footprint. It would be more likely to be a symbol for a tribe saying that they were there and from the look nora and ren shared when they looked at it in episode 2, they likely know who's symbol it was and it is also likely the same people who destroyed there home.
