ABOUT 200 MILLION YEARS AGO dinosaurs the size of kangaroos walked through mud beside Lake Hitchcock leaving footprints with tail-drag marks in the mud. We can still see those tracks today as fossils in the exposed rock layers. Last week a field mouse skittered across the snow down by the Mill River leaving its tiny tail-drag marks in the snow. From the time-standpoint of the known universe which is 13.8 billion years old, these two events were separated by the briefest of moments in time.
