The Process of Preservation
- Trackmaker makes footprint.
After this period the tracks become baked by the sun and therefore resistant to erosive
forces of wind, rain and tidal waters.
- As new deposition occurs, the track acts as a sediment trap until the track is filled.
- Extraneous sediment is lost, leaving casts in the prints which will protect the shape of the print.
- Lithification of deposited layers has occurred.
- Ichnologists use tools to extract the cast and reveal the footprint mould.
