It describes a long series of rock [[strata]] which geologists decide should be given a name. An example is the [[Mesozoic]] era, when [[dinosaur]]s lived on the [[Earth]]. <br /> <br /> An era is made up of [[period (geology)|periods]], and several eras make up an [[eon]]. The [[Phanerozoic]] eon started about 541 million years ago (mya). It is made up of the [[Paleozoic]] era (from the Greek for &quot;oldest life&quot;), the [[Mesozoic]] era (&quot;middle life&quot;) and the [[Cainozoic]] era (&quot;latest life&quot;).<br /> <br /> <br /> {{Wiktionary|era}}<br /> <br /> <br /> [[Category:Units of time]]<br /> [[Category:Eras| ]]<br /> [[Category:Geology]]</div>
