What is the longest - Jurassic period Carboniferous period Paleozoic era or Mesozoic era?
The Paleozoic era represents the longest timespan from the list. It ran from 542 to 251 million years ago, a total time of 291 million years.

For completeness, the other time spans mentioned in the question are given further detail below: The Mesozoic era ran from 251 to 65.5 million years ago. A timespan of 185.5 millions years The Carboniferous period ran from 359.2 to 299 million years ago, A timespan of 60.2 millions years. The Carboniferous period is one of the subdivisions of the Paleozoic era. The Jurassic period ran from 199.6 to 145.5 million years ago. A timespan of 54.1 millions years.
