📅 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.
00:01:06 Overview of the Phanerozoic Eon, a time when marine invertebrates dominated the ocean, followed by the appearance of land plants and vertebrates. The supercontinent Rodinia broke apart, giving rise to Pangea.
🌊 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.
00:02:11 The Phanerozoic Eon, known as the Middle Animals era, was a time of rapid change. It was characterized by the formation of the supercontinent Pangea, the rise and fall of dinosaurs, and the emergence of mammals and birds.
🦖 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.
00:03:14 The Phanerozoic Eon consists of the Paleozoic, Mesozoic, and Cenozoic eras. The Cenozoic era is known as the age of mammals, birds, and flowering plants, lasting approximately 65 million years.
🌍 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.
00:04:19 The Phanerozoic Eon is a period where flowering plants, insects, apes, and humans appear. Ice ages occur, continents move, and mountain ranges form.
🌸 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.
