The first date has to be an estimate, but since the dinosaurs effectively dominated the mammals by the start of the Jurassic (201 mya) we could reasonably credit them with 136 million years "in charge" using 65 mya (the end of the Cretaceous and a spectacular change in the fossil record) as the second.

Who are hangs around the fort people?
These bands lived next to the agencies and tried to live like members of the dominant culture, they were rewarded by receiving the best and most of government aid.

Those who were adopting the dominant culture's ways became the "hang-around-the-fort Indians", and that term became a contemptuous epithet used by those who were trying to live the traditional ways of the Lakota culture.
