The youngest geological period is the Quaternary Period, which began about 2.6 million years ago and includes our current time, the Holocene Epoch, starting around 11,700 years ago after the last ice age, making the Holocene the most recent geological time interval. If you mean a specific cooling event within that, the Younger Dryas (c. 12,900–11,700 years ago) was the most recent short-term cold snap before the Holocene.
The Cenozoic is the youngest era and the name means “new life”.
Dinosaurs roamed the Earth in the Mesozoic Era, which is split into the Triassic, Jurassic and Cretaceous periods. They first emerged during the Triassic period around 245 million years ago. At the time, all continents were part of a single land mass – the supercontinent Pangea.
The Younger Dryas occurred during the transition from the last glacial period into the present interglacial (the Holocene). During this time, the North American, or Laurentide, ice sheet was rapidly melting and adding freshwater to the ocean.
The oldest subdivision of the time scale is the Precambrian (symbolized by PC, X, Y, or Z in the GRI GIS data). The Precambrian is split into three eons: Hadean (4600-4000 MYA), Archean (4000-2500 MYA), and Proterozoic (2500-541 MYA).
There are 22 defined periods, with the current being the Quaternary period. As an exception, two subperiods are used for the Carboniferous Period. An epoch is the second smallest geochronologic unit. It is equivalent to a chronostratigraphic series.
Million years ago, abbreviated as Mya, Myr (megayear), or Ma (megaannum), is a unit of time equal to 1,000,000 years (i.e. 1×106 years), or approximately 31.6 teraseconds.
Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests the onset of the next ice age could be expected in 10,000 years' time.
The Ice Ages began 2.4 million years ago and lasted until 11,500 years ago.
When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.
Nigersaurus had so many teeth it has been dubbed "the mesozoic lawnmower," but while it may may have looked like "a hammerhead shark with legs," even it had a match.
If you were to visit Earth about 65 million years ago, during a time called the Paleocene, you would find thick forests where the descendants of mammals that survived the asteroid impact were starting to get big. Triceratops would have been extinct for a million years.
Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Calendar Year: It's the 2020s, the third decade of the 21st century. History Books Call It: The Modern or Contemporary Era. Science & Geology Name It: Cenozoic Era, Quaternary Period, Holocene Epoch.
Ten eras are recognized by the International Union of Geological Sciences: the Eoarchean Era (4.0 billion to 3.6 billion years ago), the Paleoarchean Era (3.6 billion to 3.2 billion years ago), the Mesoarchean Era (3.2 billion to 2.8 billion years ago), the Neoarchean Era (2.8 billion to 2.5 billion years ago), the ...
The Paleozoic Era is further divided in to seven periods/sub-periods: the Cambrian, the Ordovician, the Silurian, the Devonian, the Mississippian, the Pennsylvanian, the Permian. A few examples of NPS resources in each time Period are highlighted below, from youngest to oldest.
Earth's last ice age ended around 11,700 years ago and a new study predicts the next one should be 10,000 years away. But the researchers say record rates of fossil fuel burning that are increasing global temperatures will likely delay this due date.

Humans were able to survive the Ice Age due to evolution. Human brains developed to be larger, and humans began walking completely upright. With these advantages they were able to better plan ahead and to think about how to survive their situation. They began tracking the movement of herds for food.
Global temperature is projected to warm by about 1.5 degrees Celsius (2.7° degrees Fahrenheit) by 2050 and 2-4 degrees Celsius (3.6-7.2 degrees Fahrenheit) by 2100.
This year will conclude as the second hottest on record, surpassed only by 2024. It continues a recent trend of exceptional, unexplained warming. The last three years have been, by a wide margin, the hottest ever recorded.
2030 is considered a critical deadline, a "point of no return," for climate action because scientists warn that surpassing 1.5°C (2.7°F) of global warming around that time risks triggering irreversible "tipping points," like melting permafrost releasing methane or Amazon rainforest dieback, leading to self-reinforcing warming loops that humanity can't stop, making catastrophic climate change much harder or impossible to avoid, even with future emissions cuts, according to reports from the UN IPCC, Science News and other experts.
The groups and their names are as follows: Decade = 10 years. Century = 100 years.
millennia or millenniums) is a period of one thousand years, one hundred decades, or ten centuries, It is also sometimes called a kiloannum (ka) or kiloyear (ky).
Our current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
