The mode of organic preservation in these sites would be different, says Ehlmann, a co-investigator on the 2020 rover's mast camera instrument.

Lateritic soil development has resulted in poor organic preservation and facilitated insect bioturbation, which has demanded an integrated micro-macro scale approach to building a reliable geochronology.

Whilst a fairly substantial suite of radiocarbon dates is available for this techno-complex [91, 92], the individual dates are of highly variable quality and context, and the majority of sites lack absolute dates due to overwhelmingly poor organic preservation at most sites.

Adding humans to the list of taphonomic agents will not make the interpretation of such layers easier, but it is worth stressing that tephra may, due to it being inorganic, provide a particularly useful (at times perhaps sole) dating tool in archaeological sequences with poor organic preservation.
