Several trackways from the Steven C. Minkin Paleozoic Footprint Site in Walker County. The trackways were made by wingless monuran insects and indicate heavy use of a mud flat, because all of the trackways must have formed during a short span of time. Scientists know these tracks were made by monurans because the same kinds of insects are alive today and make the same kinds of tracks. Scale in centimeters.
