Of or pertaining to, or designating, the older division of geological time during which life is known to have existed, including the Silurian, Devonian, and Carboniferous ages, and also to the life or rocks of those ages. See Chart of Geology.
"middle times" because the mesozoic was in between the paleozoic ("early times") and the Cenozoic ("current times")
The Paleozoic literally translates into Ancient Life.It comes from the Greek Palaios meaning ancient or primitive and zoe meaning life.
Paleozoic
The first period in the Paleozoic Era was the Cambrian.
During the Paleozoic Era, there were two major landmasses: Laurasia and Gondwana. These landmasses eventually broke apart through the process of plate tectonics and formed the continents that we recognize today.
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.

The Paleozoic
No. There were no snakes in the Paleozoic. The first snakes appeared in the late Meoszoic. Cobras appeared in the Cenozoic.
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. The Mississippian period is a part of the Paleozoic era, along with the Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, and Permian periods.
Yes. If no animals survived from the Paleozoic into the mesozoic, then there would be no animals today.
