65 million years
The 3 eras of geologic time is Palezozoic era, Mesozoic era, and Cecozoic era
The last period of the Paleozoic Era is the Permian Period, which lasted from about 299 to 252 million years ago. It ended with the largest mass extinction event in Earth's history, wiping out around 90% of marine species and 70% of terrestrial species.
An era is a period of geologic time which varies in length but is many millions of years. For instance, the current era of geologic time, the Cenozoic, has lasted for over 65 million years to date.

they last like 65million years
forever
About 300 years
Around 70 years
almost 2011 years (its the era we are in)
20 years
This period lasted from about 1800-1850.
The Cenozoic Era lasted 65.5 million years ago to the present day!
It lasted more than a few years
The Paleozoic Era Lasted about 2799. You can add all the numbers of the: Permian, Carboniferous, Devonian, Silurian, Ordovician, and the Cambrian. Add all of there numbers of how long each era lasted. So that's how long the Paleozoic Era Lasted ("2799")
