The Paleozoic era does not include the Mesozoic and Cenozoic eras, which follow it in the geological time scale. The Paleozoic spans from about 541 to 252 million years ago and is characterized by significant evolutionary developments, including the emergence of fish, amphibians, and early reptiles. It is marked by major events such as the Cambrian explosion and the Permian extinction.
Paleozoic rocks are a category of geological rock formations that were formed during the Paleozoic Era, which lasted from about 541 to 252 million years ago. They include a wide variety of sedimentary, metamorphic, and igneous rocks that were created during this time period and hold valuable information about the Earth's history. These rocks can be found all over the world and are often important for understanding past geological events and the evolution of life on Earth.
Trilobites, eurypterids, and blastoids are examples of Paleozoic invertebrates that became extinct by the end of the Paleozoic era. These marine creatures were once diverse and abundant but disappeared due to various environmental changes and extinction events at the end of the era.
Yes. If no animals survived from the Paleozoic into the mesozoic, then there would be no animals today.
During the early Paleozoic era, marine invertebrates such as trilobites dominated. In the middle Paleozoic, fish and early land plants became more prominent. By the late Paleozoic, amphibians, reptiles, and forests of ferns and seed plants were thriving.
The second era in geological time is the Paleozoic era, which lasted from about 541 million years ago to 252 million years ago. It is known for the evolution of early marine life, the colonization of land by plants and animals, and the formation of the supercontinent Pangaea. Major events during this era include the Cambrian explosion, the colonization of land by plants during the Silurian period, and the mass extinction at the end of the Permian period.
Paleozoic
The first period in the Paleozoic Era was the Cambrian.
The periods of the Paleozoic Era are named for the locations where the rock formations that represent these time periods were first studied and defined. Examples include the Cambrian period (named after Cambria, the Latin name for Wales) and the Devonian period (named after Devonshire, England).
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.

No. There were no snakes in the Paleozoic. The first snakes appeared in the late Meoszoic. Cobras appeared in the Cenozoic.

Yes. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
