English: Footprint with Seeds |
||||
Description |
English: A close-up image of a single footprint that is surrounded by black seeds. A NPS ruler is adjacent to provide size context. Footprint measures over 150mm. Trenches are useful to researchers in revealing multiple levels around the same area. Fossilized human footprints have been found at various sedimentary levels as depicted in the image. These suggest that human activity has occurred over a longer period of time, as opposed to an isolated event.
