OK: Sci-fi short story, remembered from an anthology, H. Beam Piper-esque, I'm 64 so could be old.
A ship of human scientists with a small security contingent land on an earth-like planet. Ancient ruins with architecture possibly indicates near-human stature; residual radiation, rocket strikes? Advised by Security to avoid current animal-like residents, who do not seem to be civilized -- can't be caught for study, tremendously long throwing arms with deadly accuracy and thus avoided, no evidence of speech, language, any communication other than menace. Ape-like. Not seriously considered the aboriginals.
Single archaeologist wanders from group, turns a corner and is confronted by one of the residents who then speaks to him in his own terran language. Says to the effect of ...we had hoped you would return to some of your old places.... The scientist manages to keep his cool but is confused and asks for clarification. The aboriginal then looks around at the ruins, returns his gaze and says to the effect of ...these ruins... they are not ours... they are yours.
Anyone recognize this? Title, author, anything?
