The Paleozoic Era is the first and longest era in the Phanerozoic Eon, and is one of three, the two other eras being the Mesozoic and Cenozoic. Paleozoic is derived from Greek and means "ancient life."
The Paleozoic lasted from roughly 542 to 251 million years ago, and is subdivided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The era began with the advent of multicellular life, and ended with the most severe mass extinction in Earth's history, destroying 96% of all marine species and 70% of terrestrial vertebrate species.
The Paleozoic Era saw the development and diversification of all the modern phyla and most of the groups of life we see today, including invertebrates, arthropods, fish, amphibians, and reptiles. Most groups of marine and terrestrial plants also arose and flourished during this time. Mammals and birds would not appear until the Mesozoic Era, which came after.
What else can I help you with?
The end of the Permian period was also the end of what Era?
The permian period was the end of the paleozoic era.
Which describes the correct order of the geologic time scale from oldest to most recent?
ok im going to start off by saying this, the last answerer is stupid, and doesnt know what he is talking about. it goes from: PERIOD ERA EPOCH there you go ;)
What is the correct order for the major geological eras?
Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era
What era formed Gondwana and Laurasia?
The formation of Gondwana and Laurasia occurred during the Paleozoic era, specifically during the late Precambrian and early Paleozoic periods. Gondwana and Laurasia eventually merged to form the supercontinent Pangaea during the late Paleozoic era.
What geologic era lasted longest?
The Cenozoic Era is the most recent geologic era and has lasted for around 65 million years, making it the longest era to date. During this era, mammals diversified and dominated the Earth's ecosystems.
What is the 1st period in the Paleozoic Era?
The first period in the Paleozoic Era was the Cambrian.
What era is silurian in?
The Paleozoic Era
What is the third geological era?
paleozoic era
What era is the era of ancient life?
i cant answer this :(
Is the mississippian period in paleozoic era?
Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
What era were the brachiopods from?
Paleozoic
Is paleozoic the second era?
No, the Paleozoic era is the first of three eras in the Phanerozoic eon. It spans from around 541 million years ago to 252 million years ago. The following era is the Mesozoic era, which is the second era in the Phanerozoic eon.
What is another name for the Paleozoic Era?
The Paleozoic Era is also known as the age of ancient life.
The Cambrian Period was part of what 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.
What main characteristic distinguishes the fossil record of the Paleozoic Era from that of the Precambrian Era?
The main characteristic that distinguishes the fossil record of the Paleozoic Era from the Precambrian Era is the appearance of diverse and complex multicellular organisms in the Paleozoic Era. In the Precambrian Era, the fossil record primarily consists of simpler single-celled organisms. Additionally, the Cambrian Explosion, which occurred at the beginning of the Paleozoic Era, marked a significant increase in the diversity of life forms.
What era did the reptiles appear?
Reptiles first appeared during the Paleozoic Era, specifically the Carboniferous System of the Paleozoic Era. That was about 320 million years ago.
What is ancient life?
The Paleozoic Era.
