Geologists Debate Start of Anthropocene Epoch
Geologic time is divided into intervals. The largest are eons, followed by eras, periods, and epochs. We are in the Phanerozoic Eon, Cenozoic Era, Quaternary Period, and Holocene Epoch. But geologists may declare that the Anthropocene Epoch began in 1965, when nuclear bomb testing began leaving radioactive geological evidence. Happy New Epoch!
