What is the correct order of geological eras?

The correct order of geological eras is Palaeozoic, Mesozoic, and then Coenozoic. This sequence reflects the historical timeline of Earth's development and the significant evolutionary milestones that occurred during each era.

The Palaeozoic Era, which began around 540 million years ago, is known for the emergence of diverse marine life, the development of land plants, and the first amphibians and reptiles. Following this, the Mesozoic Era, often referred to as the "Age of Reptiles," lasted from about 252 to 66 million years ago and includes the rise and dominance of dinosaurs along with the development of early mammals and birds.

The Coenozoic Era, which began approximately 66 million years ago and continues to the present, is characterized by the dominance of mammals and birds after the mass extinction event that ended the Mesozoic. This era has seen significant developments in mammalian evolution and the rise of human beings.

Understanding this sequence not only helps in grasping the timeline of Earth's history but also emphasizes the evolutionary processes that shaped the planet's biosphere through each era. The placement of the eras in the incorrect order would fail to accurately represent the fossil records and key evolutionary trends that
