Plants from the paleozoic era
Progressing from the oldest to the current, the four major eras of Earth’s geological history are Precambrian, Paleozoic, Mesozoic and Cenozoic. The current GTS era, the Cenozoic Era, began 65.5 million years ago.The late Paleozoic rock strata hold the evidence of great forests of primitive plants thriving on land with their remains forming the great coal beds of Europe and eastern North America. At the end of the Paleozoic era, the fossil record includes the first large, sophisticated reptiles and the first modern plants . Paleozoic Era. Tens of thousands of feet of Paleozoic sediments have been found in the central United States alone, layer upon layer upon rock. We can look at these from the lowest level of rock, from nearly 570 million years ago, right up through the whole Paleozoic; and see the succession of changing life as we go through these rock cuts.

The Mesozoic Era is often referred to as the Age of Reptiles because most dinosaurs lived there.Geophysical. Oxygen levels begin at 20% of the atmosphere, and then steadily increase to 27.5%. Carbon dioxide levels begin at ~4,200 ppm and drop to 2,900 ppm in the Middle Devonian, then increasing to ~3,500 ppm by the Period's end. The colonization of land by plants led to the following changes in carbon dioxide and oxygen ( Dahl & Arens 2020):
The Phanerozoic Eon is divided into three eras—the Paleozoic, the Mesozoic, and the Cenozoic ( Figure (below). They span from about 540 million years ago to the present.
