Ronnie continues: [Note that Anne reordered a few paragraphs to keep the suspense going.]
The foreclaws of a badger are very elongate, like the ones you see on the forefoot in [the photos above]. However, one species of skunk has the same characteristic foreclaws, just on a smaller body.
I don't think that is a badger burrow. That's a skunk den. Skunks dig dens into/under the ground often near other structures like bridges, culverts, river banks, tree trunks, etc.
The specimen is a skunk.
Which species of skunk? The teeth are the final clue....
