I hardly ever base my river decision here on villain's range in as precise a way as other posters in this thread are. IMO it is not necessary and way overcomplicating the decison.

Much more important IMO is villain's image and the action in the hand. Put those together and I think this is a stupendously easy fold. I don't think it's within a million miles of being close.

This kind of "big picture" element to the hand is so clear IMO that it is not necessary to make a decision based on a marginal "small picture" element of the hand (namely, estimating a precise range). If you try to make that precise a judgment it is easy to get it a little bit wrong, but lose a lot of money.

I think this also reminds me of one of M&S Concepts, along the lines of: the best piece of information you have at any given moment is the bet just gone in, and it should take precedence in your decision. As this isn't a bluff with a worse hand, I think that reinforces the fold.

I like how hero played hand up to river call.

Opinion not advice, as I suck every day for hours on end.
