The geologic time scale is an essential tool for understanding the history of Earth and the evolution of life. In this lesson, explore the principal eons, eras, periods, and epochs that help us track major events in geologic history.
A group of geologists released a recent study saying that the Earth has entered a new geologic epoch, called the Anthropocene

This video from the Museum's Florida Fossils exhibit describes the Oligocene, 34 million to 24 million years ago. Global climates became cooler during the Oligocene, causing sea levels to drop. At least the northern portion of the Florida platform, once abundant with tropical, marine habitats, was now land.
Early immigrants to the Florida peninsula included amphibians, reptiles, bats, shrews and rabbits. Also, predators tracked dwarf horses and the strange, hoofed mammals, oreodonts and chalicotheres, onto this new land. In the ocean, huge sharks plied the depths, while several kinds of sea cows were abundant near shore.

With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and their environments. Life is powerful, and in order to understand how living systems work, you first have to understand how they originated, developed and diversified over the past 4.5 billion years of Earth's history. Hang on to your hats as Hank tells us the epic drama that is the history of life on Earth.

A History of Science Perspective
Human activity is leaving a pervasive and persistent signature on Earth. Vigorous debate continues about whether this warrants recognition as a new geologic time unit known as the Anthropocene. The appearance of manufactured materials in sediments, including aluminum, plastics, and concrete, coincides with global spikes in fallout radionuclides and particulates from fossil fuel combustion. Carbon, nitrogen, and phosphorus cycles have been substantially modified over the past century. Rates of sea-level rise and the extent of human perturbation of the climate system exceed Late Holocene changes. Biotic changes include species invasions worldwide and accelerating rates of extinction. These combined signals render the Anthropocene stratigraphically distinct from the Holocene and earlier epochs.

Thanks for watching :)
NOTE: For all visitors.
I know there are some misspellings in the image texts. All images are from the Celestia space simulator, not mine ;)
In 2:35 you can see a red impact mark in the map, I know the best known massive extintion was in the Cretaceous. But it was in the last stage of the period entering in the Paleocene ;)
Thanks for your understanding.

We are currently living in the Holocene epoch, but some geologists think the influence of human activity on the planet has reached a point where we have entered a new geological time period.
This means that we might have entered a new era, or epoch called the Anthropocene, which is a term that was first popularized by Nobel laureate Paul Crutzen in the year 2000.
An epoch typically lasts tens of millions of years, so the impact on the planet caused by human activity like industrial pollution and nuclear disasters would have to be evident for that long.
Experts can’t agree exactly if or when to start measuring the new epoch, and some argue that there just isn’t sufficient evidence yet that human activity has changed the planet.
James Ogg, a stratigrapher with Purdue University and the China University of Geosciences is quoted as saying: "The Anthropocene is a very useful term, because it helps show the dramatic impacts we’ve had on all aspects of the planet. But on the geologic time scale, you need a place and time that can be correlated around the world…”
Adding to the confusion is the name itself. The ending “cene” implies an epoch, but smaller measurements for geological periods might apply to the Anthropecene like an age, which only lasts for millions of years.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

Epoch (geology)
In geochronology, an epoch is a subdivision of the geologic timescale that is longer than an age and shorter than a period. We are currently living in the Holocene Epoch of the Quaternary Period. Some scientists have proposed that we are currently living in the Anthropocene Epoch, although this has yet to be confirmed by the International Union of Geological Sciences. Rock layers deposited during an epoch are called a series. Series are subdivisions of the stratigraphic column that, like epochs, are subdivisions of the geologic timescale. Like other geochronological divisions, epochs are normally separated by significant changes in the rock layers they correspond to.
Epochs are most commonly used for the younger Cenozoic Era, where a greater collection of fossils has been found and paleontologists have more detailed knowledge of the events that occurred during those times. They are less commonly referred to for the other eras and eons, since less fossil evidence exists that allows us to form a clearer view of those time periods.

Geology
Geology (from the Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).
Geology gives insight into the history of the Earth by providing the primary evidence for plate tectonics, the evolutionary history of life, and past climates. Geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and for providing insights into past climate change. Geology also plays a role in geotechnical engineering and is a major academic discipline.
Geologic materials
The majority of geological data comes from research on solid Earth materials. These typically fall into one of two categories: rock and unconsolidated material.

The Anthropocene and the Near Future: Crash Course Big History #9
In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in...

Geologic "Eras", animated
Make a LineStorm video like this at your school! We'd love to animate with you! Contact LineStorm Animation at www.linestorm.com, or posborn@motionart.org. "Eras" is a fast-paced, hand-drawn, animated timeline of the four most prominent geologic eras of Earth's history -- Precambrian, Paleozoic, Mesozoic and Cenozoic. Students 12 to 15 years of age created "Eras" in the LineStorm Animation classes at the Creative Arts at Park School summer program in Brookline, Massachusetts. Originating entirely on flipbooks, "Eras" visualizes the delightful Science Song of the same name, composed by David Haines, from his oratorio, "LifeTime: Songs of Life and Evolution."

This video from the Museum's Florida Fossils exhibit describes the Oligocene, 34 million to 24 million years ago. Global climates became cooler during the Oligocene, causing sea levels to drop. At least the northern portion of the Florida platform, once abundant with tropical, marine habitats, was now land.
Early immigrants to the Florida peninsula included amphibians, reptiles, bats, shrews and rabbits. Also, predators tracked dwarf horses and the strange, hoofed mammals, oreodonts and chalicotheres, onto this new land. In the ocean, huge sharks plied the depths, while several kinds of sea cows were abundant near shore.

A History of Science Perspective
Human activity is leaving a pervasive and persistent signature on Earth. Vigorous debate continues about whether this warrants recognition as a new geologic time unit known as the Anthropocene. The appearance of manufactured materials in sediments, including aluminum, plastics, and concrete, coincides with global spikes in fallout radionuclides and particulates from fossil fuel combustion. Carbon, nitrogen, and phosphorus cycles have been substantially modified over the past century. Rates of sea-level rise and the extent of human perturbation of the climate system exceed Late Holocene changes. Biotic changes include species invasions worldwide and accelerating rates of extinction. These combined signals render the Anthropocene stratigraphically distinct from the Holocene and earlier epochs.

Thanks for watching :)
NOTE: For all visitors.
I know there are some misspellings in the image texts. All images are from the Celestia space simulator, not mine ;)
In 2:35 you can see a red impact mark in the map, I know the best known massive extintion was in the Cretaceous. But it was in the last stage of the period entering in the Paleocene ;)
Thanks for your understanding.

We are currently living in the Holocene epoch, but some geologists think the influence of human activity on the planet has reached a point where we have entered a new geological time period.
This means that we might have entered a new era, or epoch called the Anthropocene, which is a term that was first popularized by Nobel laureate Paul Crutzen in the year 2000.
An epoch typically lasts tens of millions of years, so the impact on the planet caused by human activity like industrial pollution and nuclear disasters would have to be evident for that long.
Experts can’t agree exactly if or when to start measuring the new epoch, and some argue that there just isn’t sufficient evidence yet that human activity has changed the planet.
James Ogg, a stratigrapher with Purdue University and the China University of Geosciences is quoted as saying: "The Anthropocene is a very useful term, because it helps show the dramatic impacts we’ve had on all aspects of the planet. But on the geologic time scale, you need a place and time that can be correlated around the world…”
Adding to the confusion is the name itself. The ending “cene” implies an epoch, but smaller measurements for geological periods might apply to the Anthropecene like an age, which only lasts for millions of years.
