Paleozoic
The Carboniferous is considered to have started 354 million years ago and ended 290 million years ago.
The Jurassic period took place before the Cretaceous era and after the Triassic era. It started around 199 million years ago and ended about 44 millions years later. (145 million years ago if you can't do the maths).
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
The Precambrian period was from 4600 million years ago to about 542 million years ago.
Paleozoic
570 million years ago falls within the Ediacaran Period, which was characterized by the appearance of complex multicellular life forms such as early animals and algae. This period ended with the Cambrian Explosion, a rapid diversification of life forms around 541 million years ago.

About 3800 million years ago.
The Carboniferous period occurred approximately 300 to 360 million years ago.
490 million years ago.
It lasted 64 million years.
The Paleozoic Era started around 541 million years ago and ended about 252 million years ago, spanning a duration of approximately 289 million years.
if you meant paleozoic it is the era of time between 230 million and 570 million years ago. Best known as being the time of the advent of fish insects and reptiles.
The era that started 4.6 billion years ago is known as the Hadean era. It began with the formation of the Earth and ended around 4 billion years ago. This era was characterized by intense heat and frequent bombardment by asteroids.
