Fig. 5. Mean touch-down and lift-off positions of fore- and hindlimbs of (A) Tupaia glis and (B) Galea musteloides sorted by body mass. Note the constant touch-down position of both fore- and hindlimbs and the increasing retraction of limb segments at lift-off. Also the underweight tree shrew P39(2) is comparable in its kinematic parameters to younger individuals of the same body mass.
