Australia in the Mesozoic was nothing like it is today. It did not exist as a separate landmass, its position on the globe was much further south and the climate and plants were very different. By the end of the Paleozoic era evolution had caused complex land and marine animals to exist. Much of the land was dominated by large reptiles, the early ancestors of the dinosaurs. However, the event that marked the end of the Paleozoic period was the massive extinction that wiped out nearly 96% of all marine life and 70% of land animals.Paleozoic (541-252 million years ago) means 'ancient life.' The oldest animals on Earth appeared just before the start of this era in the Ediacaran Period, but scientists had not yet discovered them when the geologic timescale was made. Life was primitive during the Paleozoic and included many invertebrates (animals without backbones) and the earliest fish and amphibians.During the Phanerozoic eon, continents drifted about, eventually collected into a single landmass known as Pangea, and then split up into the current continental landmasses..

Plants moved onto land.Ordovician (490–435 Myr BP) Cambrian (543–490 Myr BP) Precambrian (beginning of the Earth – 570 Myr BP) For the Paleozoic era (570–236 Myr BP), more reliable data on the oceanic temperatures exist only for the late period ( the Permian ). However, there is evidence of large climate variations during the Paleozoic.Mesozoic. Mesozoic (252-66 million years ago) means 'middle life' and this is the time of the dinosaurs. This era includes the Triassic, Jurassic, and Cretaceous Periods, names that may be familiar to you. It ended with a massive meteorite impact that caused a mass extinction, wiping out the dinosaurs and up to 80% of life on Earth.All species of life—including humans—evolved into their present-day forms over the course of this era, which hasn't ended and most likely won't until another mass extinction occurs. Here is a brief look at the four periods of the Geologic Time Scale that track the Earth's history: Precambrian, Paleozoic, Mesozoic, and Cenozoic.The period, and the Paleozoic era, came to a calamitous close 251 million years ago, marking a biological dividing line that few animals crossed.
