An empirical cumulative distribution function of elevations and/or depths. A curve that illustrates the relative portion of surface area occurring at different depths or elevations within a specified region.

Fossilized behaviour of extinct organisms (traces, tracks, burrows, borings, footprints, nests, dung, gastroliths, burrow, stomach contents, etc.). Ichnofossils record the activity (movenment and behavior of animals). Trace fossils are most commonly represented in the geologic record by features formed through animal activity in a substrate of some sort, such as sediment, rock, or wood. These features include burrows, tracks, trails, and borings.
