Relatively recently in the Cenozoic era
This is the Cenozoic era, near the boundary of Quaternary and Neogene periods, and therefore near the boundary of the Pleistocene and Pliocene epochs. Please see the link.
the Cenozoic era which was 66 million years ago & advanced
The Cenozoic era started 65 million years ago.
We live in the Quaternary period.
Relatively recently in the Cenozoic era
Humans first appeared in the Paleolithic era, around 2.5 million years ago. This era is characterized by the use of stone tools and the development of early human species like Homo habilis and Homo erectus.
This is the Cenozoic era, near the boundary of Quaternary and Neogene periods, and therefore near the boundary of the Pleistocene and Pliocene epochs. Please see the link.
the Cenozoic era which was 66 million years ago & advanced
The Tertiary Period (including the Pliocene, Miocene, Oligocene, Eocene, and Paleocene Epochs) lasted from about 65 million years ago to 1.8 million years ago. It is part of the Cenozoic Era, along with the Quarternary Period.
The Cenozoic era started 65 million years ago.
The Cenozoic era
The Cenozoic Era has the greatest variety and quantity of mammalian life.
Cenozoic
Epochs
The Paleozoic, the Mesozoic and the Cenozoic are all divided into periods and epochs.
They are divisions of geologic time, based largely on the fossil record of organisms. Eras are longer subdivisions of time which are further subdivided into periods and epochs. For instance, we are currently in the Holocene epoch of the Quaternary Period, and the larger Cenozoic Era.
