Paleozoic
This three eras was included in the Proterozoic Eon.The first Era was the Paleoproterozoic Era;next is the Mesoproterozoic Era;then the last is the Neoproterozoic Era. This another three eras was according to the Phanerozoic Eon.The first Era was the Paleozoic Era;followed up by the Mesozoic Era;then the lastly was the Cenozoic Era.
The crown eukaryotes are known to have existed in the paleoproterozoic era. Crown eukaryotes are an artificial group of eukaryotic organisms found at the top of molecular phylogenetic trees including both eukaryotes and prokaryotes. They were originally thought to represent a late step of eukaryotic evolution because they include multicellular and macroscopic lifeforms that represent the majority of the biomass of the planet while accounting for less than 1% of the genetic diversity.
The Regency Era
No, the Mississippian period is part of the Carboniferous period, which is within the Paleozoic era. So, the Mississippian period is part of the Paleozoic era, not a separate era on its own.
The end of the Permian period marked the end of the Paleozoic Era and the beginning of the Mesozoic Era.
The Paleozoic Era.
The Cambrian Period was from about 543 to 490 million years ago. It is the earliest period in the Paleozoic ("old life") Era. Until relatively recently paleontologists thought this marked the beginning of life. Primitive life is now know from the Pre-Cambrian Eon.
C - PALEOZOIC ERA
Ther Permian was the last period of the Paleozoic era.
The Paleozoic
paleozoic
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.
The permian period was the end of the paleozoic era.
The Paleozoic era is the longest out of the options given, lasting from about 541 million years ago to 252 million years ago. The Jurassic period is part of the Mesozoic era, which followed the Paleozoic era. The Carboniferous period occurred within the Paleozoic era.
The Paleozoic Era has seven Periods beginning with the Cambrian Period. The last period was the Permian Period which was from 290 Million to 248 million years ago.
