All of them, characterized by being tridactyl, as long as wide, with high divarication between digits II-IV, some pad impressions in each digit, claw marks, a medial notch and a circular heel pad impression, are classified as indeterminate ornithopod footprints.
Footprint length (FL), footprint width (FW), trackway deviation (TD), external trackway width (eTW), pace length (PL), stride length (SL), pace angulation (ANG), footprint rotation (FR), digit divarication angles (II^III, III^IV, II^IV), height (H), speed using the formula of Alexander (1976) (V1), speed using the formula of Demathieu (1986) (V2) and digit III projection (TE).
Those patients who had significant
divarication of the recti with umbilical/ paraumbilical hernia were considered for
divarication correction with correction of the hernia with abdominoplasty when patient consented for the same.
The photographs were imported into the public-domain image processing and analysis program ImageJ (Rasband 1997-2004) in order to obtain track measurements, including length, width and angle of divarication. Due to deformation, however, the track measurements reported herein are approximations of those of the original track.
The total angle of divarication between the digits is 113[degrees], and the angles of divarication between the successive digits are as follows: I-II = 54[degrees], II-III = 33[degrees], and III-IV = 28[degrees].
