- Wang et al. (2024) study Cambrian trace fossils assigned to the ichnogenus Climactichnites from the Elk Mound Group (Blackberry Hill, Wisconsin, United States), Archaeonassa from the Sellick Hill Formation (Australia) and Palaeobullia from the Buen Formation (Greenland), produced by animals moving on land millions of years before full terrestrialization, and interpret molluscs as most likely tracemakers; in the online supplemental material of the study the authors also argue that trace fossils from the Elk Mound Group assigned to the ichnogenus Protichnites resemble traces produced by marine gastropods, and that their asymmetry might be a result of chirality of mollusc shells.{{cite journal |last1=Wang |first1=Z. |last2=Davies |first2=N.
