Roman numerals = divarication angles between indicated pedal digits, L/R = left/right, MTD = maximum track depth, P = pace or step length, PA = pace angulation, S = stride length, TL = track length (excluding metatarsal impression, if any), TTL = total track length (including metatarsal impression, if any), TW = track width, * = more accurate measurements taken from 2000 M.G. Lockley tracing (CU Denver Tracks Museum Tracing # T472), although tracing provides little data and present track is much more weathered, – = measurement not applicable or unobtainable.
Measurements in parentheses are approximations due to incompleteness, poor preservation of trace, or ambiguity in discerning track margin from surface sedimentary structures; subscripted numbers indicate tracks between which P, PA, and S measurements are given.
