Which period did humans appear?
Hominins first appear by around 6 million years ago, in the Miocene epoch, which ended about 5.3 million years ago.
Our evolutionary path takes us through the Pliocene , the Pleistocene , and finally into the Holocene, starting about 12,000 years ago..
What era is the age of reptiles?
Mesozoic EraAssorted parareptiles occurred throughout the Permian Period (299 million to 251 million years ago), but they largely disappeared from the fossil record by the beginning of what was to become known as the “Age of Reptiles,” the Mesozoic Era (251 million to 65.5 million years ago).
What is the longest era?
PrecambrianThe longest geologic era was the Precambrian. It began with the formation of the earth about 4.53 billion years ago, and ended about 542 million years…
What is the largest Eon?
Phanerozoic EonThe Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers 541 million years to the present, and it began with the Cambrian Period when animals first developed hard shells preserved in the fossil record.
What is longer than an eon?
A supereon is longer than an eon.

Are we in the Cenozoic Era?
The Cenozoic era, which began about 65 million years ago and continues into the present, is the third documented era in the history of Earth. … The current locations of the continents and their modern-day inhabitants, including humans, can be traced to this period.
What was the first era?
The First Era, also called the First Age, was a time period lasting 2920 years. This article is a chronological record of First Era events, from the founding of the Camoran Dynasty to the assassination of Emperor Reman Cyrodiil III.
What are the 7 epochs?
Divisions. The Cenozoic is divided into three periods: the Paleogene, Neogene, and Quaternary; and seven epochs: the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene.
What era do we live in?
CenozoicOur current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
What is the next era called?
Geological era The next-larger division of geologic time is the eon. The Phanerozoic Eon, for example, is subdivided into eras.
What is the youngest era?
CenozoicThe Phanerozoic Eon is divided into three eras, the Paleozoic, Mesozoic and Cenozoic eras. These were named for the kinds of fossils that were present. The Cenozoic is the youngest era and the name means “new life”. This is because the fossils are similar to animals and plants that are common today.
How long is the Cenozoic Era?
about 65 million yearsThe Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time.
What are the 4 eons?
The eon is the broadest category of geological time. Earth’s history is characterized by four eons; in order from oldest to youngest, these are the Hadeon, Archean, Proterozoic, and Phanerozoic.
