Palaeozoic era
The Palaeozoic Era was a very important time in the history of life.

Sep 8, 2012 · Fossils are a glimpse into the distant past and fascinate young and old alike. This free course, Life in the Palaeozoic, will introduce you to the explosion of evolution that took place during the Palaeozoic era. You will look at the many different types of creatures that existed at that time and how they managed to evolve to exist on land. The late Precambrian is the time from about 2 billion to half a billion years ago. During this long span of time, Earth experienced many dramatic geologic and climatic changes. Continents drifted. They collided to form a gigantic supercontinent and then broke up again and moved apart.
