Collected a half-dozen or so of these two-tone brown-furred beetles from malodorous carcass of a skunk that I flopped around on a sheet of 4-mill polyethylene to encourage escapees. I called them "delicate" in file name since they wilted fast in my light arena, even with frequent sprays of water.

To my eye they bear a strong resemblance to this tiny two-tone brown beetle I found on a mushroom, which has been IDed as a cholevine, and their activity suggests they could be "small carrion beetles" -- the common name for this group. Note the tibial spurs.
