text: We don't know... to competing theories would give two varying answers.\n\n1. The t-Rex was the "King" of that era being a large hunter.  Would compose that he would hunt eat a large meal and rest.  Like present time carnivores do.  Meat has a lot of carbs and therefore there is no need to eat all day like herbivores.\n\n2. This theory does not make people happy for it conflicts with what everyone has come to believe.  The t-Rex was a scavenger, eating what other pr editors left behind.  That would mean he would walk around smelling searching for an easy meal.\n\nOf course no one can tell for sure unfortunately.
