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. It is also worth noting that an era always represents a longer timespan than a period and in fact an era will be composed of a number of periods. 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. The Jurassic period is one of the subdivisions of the Mesozoic era. For further information, please see the related links.

Is an era longer than a period?
Usually, an era refers to a specific time period, normally associated with the dates of an important event, while a period is often used to refer to events that share a characteristic, but do not have exact dates. The words are sometimes used interchangeably, and it isn't necessarily wrong to do so, since the usage is varied, but traditionally a period has been shorter than an era.
