Like I said I"ve never actually watched a coon do the deed but I do know coon tracks and the picture you posted is a hind coon foot track.The poop I find usually in swamps near coon tracks and theirs a lotta seeds in it.I would say skunk coon or possum by the size and contents.I checked Olaus Muries Peterson Field Guide to tracks and he said coon,skunks and possums have similar poop and may be confused with each other.coons tend to be black to reddish,granular and they regularly eat seeds,nuts,roots,garden crops and anything they can generally chew up and swallow.the possum poop looked more broken up and i would imagine anything associated with skunk would smell like a skunk at least for awhile.
