a division of the geological time scale that belongs to the Phanerozoic eon, with the category of era and eratheme. The Paleozoic succeeds the Precambrian supereon and precedes the Mesozoic era.
-
The Cambrian is a division of the geological timescale that belongs to the Paleozoic Era; this is divided into six periods of which the Cambrian occupies the first place preceding the Ordovician. It started about 541 million years ago

Cambrian is a division of the geological timescale that belongs to the Paleozoic Era : this is divided into six periods of which the Cambrian occupies the first place preceding the Ordovician. It began about 541 million years ago, after the Proterozoic Aeon, and ended about 485 million years ago.
-
The Ordovician is the fragmentation of the geological time scale that belongs to the Paleozoic Era; This is divided into six periods of which the Ordovician occupies the second place after the Cambrian and preceding the Silurian.
-
The Silurian is a division of the geological time scale that belongs to the Paleozoic Era; this is divided into six periods of which the Silurian occupies the third place following the Ordovician and preceding the Devonian. It started 444 million years ago and ended 419 million years ago
-
The Devonian is a system and period of the geological timescale that belongs to the Paleozoic Era; this is divided into six periods of which the Devonian occupies the fourth place, following the Silurian and preceding the Carboniferous. It began about 419 million years ago and ended about 359 million years ago.
-
The Carboniferous is a division of the geological time scale that belongs to the Paleozoic Era; This is divided into six periods of which the Carboniferous occupies the fifth place after the Devonian and precedes the Permian. It begins 359 million years ago and ends 299 million years ago.
-
The Permian is a division of the geological timescale that belongs to the Paleozoic Era; This is divided into six periods of which the Permian occupies the last place following the Carboniferous. It began about 299 million years ago and ended about 251 million years ago.
-
The Mesozoic Era lasted for more than 290 million years. Also known as the Primary Era, the Paleozoic began with the disintegration of the supercontinent Pannotia and culminated in the formation of the supercontinent Pangea. It lasted more than 290 million years. Throughout this time, life on the planet evolved.

The Triassic is a division of the geological time scale that belongs to the Mesozoic Era; within this, the Triassic occupies the first place preceding the Jurassic. It began 251 million years ago and ended 201 million years ago.
-
On the geological timescale, the Jurassic Period is the second of the three periods into which the Mesozoic Era is divided (which began 252.2 million years ago and ended 66 million years ago). ... Dinosaurs proliferated and reigned, which is why it is perhaps the most famous of the Mesozoic periods.
-
The Cenozoic or Cenozoic era, a division of the geological timescale, is the geological age that began about 66 million years ago and continues to the present day. It is the third and last era of the Phanerozoic eon and follows the It was Mesozoic.
-
It is called the third and last geological period of the Mesozoic Era, the end of which is marked by the mass extinction of the dinosaurs. It spanned from 144 million years ago to approximately 65 million years ago. Its approximate duration was 79 million years.

el primer periodo de la era cenozoica. Las formas de vida de la tierra y del mar se hicieron más parecidas a las existentes ahora. Fue un período que empezó hace 65 millones de años, cuando los dinosaurios se extinguieron
-
The quaternary period began 2.6 million years ago and extends into the present. Climate change and the developments it spurs carry the narrative of the Quaternary, the most recent 2.6 million years of Earth's history.
