Comparing these fossil plants with similar ones in Europe and North America, the scientists discovered that the Qinghai-Tibet region used to be an important terminal for the diffusion of plant species in the early Cenozoic Era
, with some plant species heading west to Europe and others going east to North America.
According to Meilan Solly of the Smithsonian, the earth is "currently situated in the Phanerozoic Eon, Cenozoic Era
, Quaternary Period, Holocene Epoch and Meghalayan Age."
The Eocene Epoch is a major division of the geologic timescale and the second epoch of the Paleogene Period in the Cenozoic Era
A research group proposes that the Holocene has ended and that we are now living in the Anthropocene Epoch, in which humans are a dominant force on the planet, source: geological society of America Cenozoic Era

The Sagavanirktok Formation lies near the top in the upper Brookian layer, underlain by an unconformity at the start of the Cenozoic era
, 65 million years ago.
One occurred during the Permo-Carboniferous, some 300,000,000 years ago, and the other during the Cenozoic era
, in which we now are living.
During the Cenozoic Era
, about 65 million years ago, a species of giant shark called the Megalodon ruled and dominated the ancient seas and oceans of the world.
It was Berry's deepest hope that we were shifting out of the Cenozoic era
and into what he called the "Ecozoic" period--that is, a time when human beings would reclaim their creative orientation to our planet.
Until recently, everybody agreed that we live in the Holocene epoch of the Quaternary period, which in turn is part of the 65-million-year old Cenozoic era
, the most recent phase of the 540-million-year Phanerozoic aeon.
This basin was part of the stable Gowndwana supercontinent in the Paleozoic era and a passive margin in the Mesozoic era and it became a site of convergent orogeny in the Cenozoic era
The Earth experienced such a worst-case Super-Greenhouse episode in the Cenozoic Era
about 55 million years ago, when global temperatures suddenly spiked and stayed for several million years at around 10[degrees] to 12[degrees] (possibly even more) above current temperatures.
