What is a ancient historical artifact?

they can have some information on them like an old shoe , on the bottom it said WLA that and it was a size 3L . WLA stands for W woman L land A army. and a artifact is a old small or big object what may have been dug up or found on a battlefield , most artifacts are from wars . Artifacts are for DNA and studies to see who the people were who used them . on some Greek pots drawings were made to say who there gods were and what the believed in . dino teeth are a good artifact , so are mummy's , no if the queens tooth fell out in around 10'000 years that will be a good artifact !
