- Abstract
- Footprints are the result of a dynamic process that is dictated by nuanced
interactions between anatomy, kinematics, and substrate (Falkingham and Gatesy 2014). To date,
much of hominin track analysis has relied heavily on understanding the relationship between
pressure applied by the foot and depth of the impression left in the substrate. (Dat et al.
2010; Hatala et al. 2013). This research employs a novel approach: using biplanar X-rays and
marker-based tracking to observe the formation of the track and deformation of the skin from
below the surface of the substrate--a viewpoint that is otherwise obstructed and allows for a
more direct observation of how the foot interacts with the sediment. The resulting data will
ultimately be compared to fossilized tracks in Ileret, Kenya in order to infer how the bipedal
locomotion of ancient hominins differs from that of modern humans. In short, by investigating
how modern anatomy and walking relates to modern footprint shape, further insight is gained
into how to interpret ancient tracks. \n\nThis poster describes the work completed over the
course of the summer and denotes the beginning stages of this endeavor. At the time of this
poster submission, data was collected from a single individual. Trials will proceed in the
near future.
