Is A geologic era is a shorter unit of time than a geologic period?
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
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.
What is the silaurian period?

What eon was the mesozoic era in?
The Jurassic Period of geologic time spanned from 206 to 144 million years ago. It was preceded by the Triassic Period and followed by the Cretaceous Period, all three comprising the Mesozoic Era.
Jurassic is the period of what era?
It really wasn't an era. An Era was a much longer period of time. It was called the "Jurassic Period".
Is A geologic era is a shorter unit of time than a geologic period?
No, a geologic era is a longer unit of time than a geologic period. Geologic eras are divided into periods, which are further subdivided into epochs. The hierarchy from largest to smallest is era, period, epoch.
Which is longer era or period?
In geological time the Eon is larger than the Period. The Eon is the largest division of geological time recognised by the International Commission of Stratigraphic.The ICS have divided the time as such from largest to smallest.Super-Eon - (SuperEonothem) (Not recognised by the ICS but unofficially recognised e.g. Precambrian time)Eon - (Eonothem)Era - (Erathem)Period - (System)Subperiod - (SubSystem)Epoch - (Series)Age - (Stage)Chron - (Chronozone) (Not recognised by the ICS but is unofficially recognised usually based on reversal of earths magnetic field)
Put time divisions in order from longest to shortest?
Eon, Era, and Epoch: APEX :D
What is an era or period?
They are divisions of geologic time, based largely on the fossil record of organisms. Eras are longer subdivisions of time which are further subdivided into periods and epochs. For instance, we are currently in the Holocene epoch of the Quaternary Period, and the larger Cenozoic Era.
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.
What era did the mesoproterozoic period begin?
the mesoproterozoic was an era itself not a period.
What is the name of the subdivisions of a qeologic period?
Eon --> Era --> sub-Era --> Period We are currently in: * Phanerozoic Eon * Cenozoic Era * Tertiary sub-Era * Quaternary Period
The Cretaceous period was a part of what era?
It was part of the Mesozoic Era.
In what geologic era is the Cretaceous Period found?
It is the final period of the Mesozoic era.
What is the 1st period in the Paleozoic Era?
