The Paleozoic Era: Dawn of Life on Earth
Welcome to the Paleozoic Era, a time of dramatic beginnings and incredible diversity in Earth’s history!
This era spanned from about 541 to 252 million years ago and is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
The Paleozoic Era witnessed the emergence of complex life forms, including the first fish, insects, amphibians, and early reptiles.
It was a time of ancient oceans teeming with bizarre creatures like trilobites and giant sea scorpions, while on land, vast forests of ferns and early trees emerged.
The Paleozoic Era ended with the largest mass extinction in Earth’s history, known as the Permian–Triassic extinction event, which paved the way for the rise of dinosaurs and mammals in the following Mesozoic Era.
This era marks the beginning of life as we know it today, showcasing the resilience and evolution of organisms in response to changing environments over millions of years.
