What was the earliest epoch of the Jurassic period?
The Hettangian Epoch. The liassic epoch.
What epoch 34 - 23 million years ago?
During the time period 34-23 million years ago, the Earth was in the Oligocene epoch. This epoch was characterized by a cooling climate and the beginning of the formation of the Antarctic ice sheet. Mammals continued to diversify and evolve during this time.
First hominids appeared on earth during what epoch?
The first hominids appeared during the Miocene epoch, between 23 to 5 million years ago. This period marked the emergence of early hominids such as Ardipithecus and Australopithecus, ancestors of modern humans.
How long ago was the miocene time period?
5 to 25 Million Years ago
What is the oldest epoch in the Cenozoic era?
The oldest epoch in the Cenozoic era is the Paleocene epoch, which lasted from about 66 to 56 million years ago. It followed the extinction of the dinosaurs and saw the rise of mammals as the dominant land animals.
How many reversals occurred in Gilberts epoch?
There were about 20 magnetic field reversals that occurred in Gilbert's epoch, which spans from about 170 million years ago to 72 million years ago.
What is the stegosaurus epoch?
Stegosaurus lived between 155 and 150 million years ago. That was during the Upper Jurassic epoch.
During what era were saber-toothed tigers supposed to have existed?
Evidence suggests that saber-toothed tigers were present from the Eocene epoch to the end of the Pleistocene epoch. This spans their existence at over 42 million years before their extinction.
How long did it last Oligicine Epoch?
The Oligocene Epoch lasted from about 33.9 million years ago to 23 million years ago, lasting approximately 10.9 million years. This epoch was part of the Paleogene Period in the Cenozoic Era.

What is the epoch of prehistory from around 33.9-23 million years ago?
This is called the Oligocene Epoch.
The Miocene epoch follows the?
The Miocene epoch follows the Oligocene epoch in the geologic time scale. It lasted from about 23 million to 5 million years ago and was a period of cooling and drying climates.
What epoch 34 - 23 million years ago?
During the time period 34-23 million years ago, the Earth was in the Oligocene epoch. This epoch was characterized by a cooling climate and the beginning of the formation of the Antarctic ice sheet. Mammals continued to diversify and evolve during this time.
What time period is 1 million years ago?
1 million years ago is within the time period of the Pleistocene epoch, which lasted from about 2.6 million to 11,700 years ago. This time was characterized by numerous ice ages and the evolution of early humans.
First hominids appeared on earth during what epoch?
