London Track number 56 only shows four toes, though the fifth digit is visible in other casts. This creature seems to have been grasping the ground with its toes, and mostly with the first three digits. As it grabbed the substrate, it raised a ridge of substrate behind the line of toes which can be seen in the nighttime stills, as well as being represented as a deep furrow in the cast. This furrow measures in excess of 5 mm on the cast. Striations can be seen on the toe impressions.
