During which era did continents move into their current positions?

Explanation:
Continents move because of plate tectonics—the plates of the Earth's lithosphere slowly drift over the mantle. The big reorganization of landmasses began with the breakup of Pangaea in the late Paleozoic and continued through the Mesozoic Era, reshaping where continents sit. By the Cenozoic Era, roughly from 66 million years ago to today, those movements had largely placed the continents into their present positions, with only minor adjustments continuing to the present. So, the era when the continents moved into their current configurations is the Cenozoic.
