From my perspective, an almost perfect explanation. Furthermore, the
smallish hands would be quite useful in fine control as the breast was lowered
onto the nest. Here, I ignore the unfounded notion that T rex's arms were
buried under masses of chest-flesh, as some have suggested.
One flaw in your logic: "Bird-descendents" should read: "Bird-cousins."
