I’ve often wondered what ‘evolutionary’ requisite necessitated the production of small short arms on a T-Rex and some of its cousins?

Lack of use causing the withering?

OR

Were they just a ‘work in progress’ and beginning to become larger?

Were they coming or going?

If they were going away, shouldn’t we find fossils of older T-Rex’s with longer arms?................
