Overview of the Phanerozoic Eon and its three eras

📅 The Phanerozoic Eon consists of three eras: Paleozoic, Mesozoic, and Cenozoic.

🌍 The Paleozoic era lasted from 544 to 245 million years ago and is known for ancient life forms.

🦕 During the Paleozoic era, there were trilobites, ammonites, and other diverse marine creatures.

🌊 Marine invertebrates dominated the ocean, including coral and jawless fish.

🌿 Land plants such as ferns and trees began to appear.

🐍 The first vertebrates appeared, including tetrapods, snakes, crocodiles, reptiles, and insects.

🌍 The supercontinent Rodinia broke apart, and Pangea was formed by the end of the era.

🦖 The Mesozoic era, also known as the age of reptiles and dinosaurs, lasted from roughly 65 to 250 million years ago.

🌍 The continents were part of a supercontinent called Pangea at the beginning of the era, but over time they broke apart and started drifting.

🌡️ The climate during the Mesozoic era was warmer than today, and it saw the appearance and diversification of dinosaurs and the first mammals.

🌍 The Cenozoic era is part of the Phanerozoic eon and lasted roughly 65 million years.

🦕 The Mesozoic era is the most recent era and is known for the existence of dinosaurs.

🌸 The Cenozoic era is also referred to as the age of mammals, flowering plants, and insects.

🌸 Flowering plants and insects thrive during the Phanerozoic Eon.

🌍 The continents have moved to their present positions and several mountain ranges, including the Alps, Himalayas, and the Rocky Mountains, have formed.

🧑‍🚀 Apes and humans appear during this era, which is characterized by cooler temperatures and the occurrence of ice ages and glaciers.
