The complexity of human finger prints got more complex as humans evolved through thousands of years.
Study of the finger print complexity [if the grains can be seen clearly enough] will show what era of evolution the humanoid is theoretically from.
And if "palm reading" is real, then wouldn't that apply to the handprint?
Finally, the matter that the hand print was made out of--should have been stored somewhere as a relic, for future use/examination.
