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.

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.
When did plant life begin to appear on Earth?
Plants have been around on the Earth since the Cambrian part of the Palenzonic Era.
What danger were in the Cambrian period?
Volcanoes
What are facts about the devonian period?
The Devonian Period is a part of the Paleozoic Era, which covers the time from 541 to 252.17 million years ago. It began with the Cambrian explosion, in which most phyla of life began, and ended with the mass extinction called the Permian-Triassic extinction event.
What is The Oldest Period in the Mesozoic Era?
Statistical analysis of the fossil records indicates that somewhere around 35% of all species disappeared at the end of the Cretaceous Era (there is considerable margin for error in that figure).
What era did the Ediacaran Fauna Live?
The Ediacarian fauna are from the Cambrian Explosion. The Cambrian Explosion occurred in the Cambrian period. The Cambrian period was part of the Paleozoic era.
What is the 1st period in the Paleozoic Era?
The first period in the Paleozoic Era was the Cambrian.
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 is the time period era Cambrian where hard shelled fossils appeared?
Pre-cambrian
During what period did the first vertebrates appear?
The first vertebrates evolved during the Cambrian Explosion about 525 million years ago. The Cambrian Explosion, obviously, occurred during the Cambrian period. The Cambrian period was part of the Paleozoic era.
What is the first part of the Paleozoic era?
Cambrian.
When did large numbers of fossils first appear in the geologic record?
Large numbers of fossils begin to appear around 530 million years ago. It is called the Cambrian Explosion, because it occurred in the Cambrian period. The Cambrian period was the first part of the Paleozoic era.
What are the eras of the CAMBRIAN?
The Cambrian Period is divided into three eras: the Early Cambrian, Middle Cambrian, and Late Cambrian. These eras refer to different stages or time intervals within the Cambrian Period, which lasted from about 541 to 485 million years ago. Each era is characterized by different geological and biological events, including the diversification of early animal life.
Is the Cenozoic era before or after dinosaur extinction?
Yes, the Cambrian Period was before the Mesozoic Era
During what time period did shallow seas cover much of the land?
The Cambrian period of the Paleozoic era ;)
What are the period of the Paleozoic era?

What is Cambrian?
The Cambrian is a period of time which comes after the vendian millions of years before dinosaurs it was hotter than the Sahara with no plants or animals on land only in the seas.Geologists name the different periods of the earth's development. Adam Sedgwick named the period within the Paleozoic era the Cambrian period. The Cambrian period occurred millions of years ago and represents the first geological period of this era. During this time, living organisms evolved to be more complex than the formerly known single cellular types.
