Periods in the paleozoic era
Cambrian was the earliest geological period in the Paleozoic Era. It existed between 542.0 to 488.3 million years ago. The marine invertebrates such as the Trilobites species dominated this period. The climate was generally cold but continually got warm with receding glaciers.The Paleozoic Era, meaning "ancient life" is the first of three eras that form a part of the Phanerozoic Eon, the other two periods being the Mesozoic and the Cenozoic. The Mesozoic is the age of the Dinosaurs and the Cenozoic is the era in which we now live. The Paleozoic Era spanned a longer period of time, from approximately 542 Ma to 251 Ma.
