p. 143-146

Résumé

– Features like human footprints can be identified in two-dimensional radar profiles.

– Amplitude variations associated with footprints have been demonstrated with slices.

– Horizon detection methods are another avenue for detecting subsurface footprints.

Introduction

Reports of trace fossil footprints of modern humans and our extinct hominin ancestors are increasingly common. The best-known example occurs at Laetoli, where the footprints of several Australopithecus afarensis individuals are telling of foot morphology, bipedal biomechanics, and body size variation within the species (Leakey & Hay, 1979; Masao et al., 2016). Subsequent studies have yielded similar evidence for other hominin species as well as information about group composition, habitat use, and interaction with nonhuman mammalian species (see numerous references in Bennett and Reynolds, 2021).

Due to the environments in which footprints are commonly found and their susceptibility to erosion following exposure, rapid and accurate documentation is crucial. Laser scanning and digital photogrammetry are routinely used for this purpose (Bennett and Reynolds, 2021: 16-20). Although these tools would not be replaced by ground-based geophysics, methods like ground- penetrating...
