![]() ![]() It is the last era of the Precambrian Supereon and the Proterozoic Eon it is subdivided into the Tonian, Cryogenian, and Ediacaran Periods. ![]() Neoproterozoic – The Neoproterozoic Era is the unit of geologic time from 1 billion to 541 million years ago. It is the longest of the Phanerozoic eras, lasting from 541 to 251.902 million years ago, and is subdivided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. Paleozoic – The Paleozoic Era is the earliest of three geologic eras of the Phanerozoic Eon. Occurred: 251.902 (+/- 0.24) million years ago – 65 million years ago Mesozoic – The Mesozoic Era, also called the Age of Reptiles and the Age of Conifers, is the second-to-last era of Earth’s geological history, lasting from about 252 to 66 million years ago and comprising the Triassic, Jurassic and Cretaceous Periods. Occurred:66 million years ago – 0 million years ago It is characterized by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. Occurred: 4,600 million years ago – 4,000 million years ago EraĬenozoic– The Cenozoic is Earth’s current geological era, representing the last 66 million years of Earth’s history. As of 2016, the ICS describes its status as “informal” It began with the formation of the Earth about 4.6 billion years ago and ended, as defined by the International Commission on Stratigraphy, 4 billion years ago. Hadean – The Hadean is a geologic eon of Earth history preceding the Archean. Occurred: 4,000 million years ago – 2,500 million years ago ![]() In this time, the Earth’s crust had cooled enough for continents to form and for the earliest known life to start. Occurred: 2,500 million years ago – 541 (+/- 1) million years agoĪrchean – The Archean Eon is the second of four geologic eons of Earth’s history, representing the time from 4,000 to 2,500 million years ago. It is the most recent part of the Precambrian “supereon.” Proterozoic – The Proterozoic is a geological eon spanning the time interval from 2500 to 541 million years ago. Occurred: 541 (+/- 1) million years ago – 0 million years ago It covers 541 million years to the present, and it began with the Cambrian Period when animals first developed hard shells preserved in the fossil record. Phanerozoic– The Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. Full of facts that will confound you, inform you, and ultimately empower you, Terra Incognita guides readers to a new place of understanding, rather than to a physical location.Carboniferous (Mississippian/Pennsylvanian) The book traces the paths of peoples, cities, wars, climates and technologies, all on a global scale. Learn about: fires in the arctic the impact of sea level rise on cities around the world the truth about immigration - and why fears in the West are a myth the counter-intuitive future of population rise the miracles of health and education that are waiting around the corner, and the reality about inequality, and how we end it. Based on decades of research, and combining mesmerising, state-of-the-art satellite maps with enlightening and passionately argued analysis, Ian and Robert chart humanity's impact on the planet, and the ways in which we can make a real impact to save it, and to thrive as a species. But as Albert Einstein once said, 'you can't use old maps to explore a new world.' And now, when the world is changing faster than ever before, our old maps are no longer fit for purpose. From the moment homo sapiens learnt to communicate we have used them to make sense of our surroundings. 'Fascinating, beautiful, alarming and revelatory use of mapping and infographics' - Stephen Fry on EarthTime mapsįrom the global impact of the Coronavirus to exploring the vast spread of the Australian bush fires, join authors Ian Goldin and Robert Muggah as they trace the ways in which our world has changed and the ways in which it will continue to change over the next hundred years. 'A riveting account of humanitys most pressing challenges and innovative solutions, fusing mesmerizing maps and compelling analysis to help navigate our complex future' advance praise from Steven Pinker
