Here's a left rear paw print (both genders). It's not too different from the forepaw, although the palm (sole) is slightly longer and there's a regular claw on the index finger analog. When walking bipedally the thumbs are perpendicular to the rest of the foot, and the four middle digits are spread further apart. If the ground is soft, the claws will be dug into the earth like cleats to maintain balance. The tail is also held pressed against the ground to act as a third contact point

This reminds me of identifying animal tracks when I was in Boy Scouts.
