Paleozoic era
Marine life, Amphibians.
The Era of Ancient Life.
Yes. If no animals survived from the Paleozoic into the mesozoic, then there would be no animals today.
The Precambrian is actually the longest block (division) of time in earth geological history. But the Paleozoic era is the longest of the three "eras". The paleozoic era started about 550 million years ago and is marked by the appearance of abundant invertebrate life in the oceans. The paleozoic era ended about 225 million years ago with the forming of the supercontinent Pangaea.
Africa was located at the south pole during the Paleozoic Era.
The Paleozoic Era, because rich fossil evidence displays that early life in the time of the Paleozoic Era, there existed a dicersity of marine life.
i cant answer this :(
The Paleozoic Era.
It's not much of the organisms that dominated the paleozoic era, it's the species of animals. Alot of the larger reptiles and early ancestors of dinosaurs conquered and dominated 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.
