    Holocene

    Holocene
    The Holocene Epoch is the name scientists have given to our current period of time. This epoch began about 11,700 years ago and extends to present day. Even though the human species was well developed before this epoch, it is still often called the ''Age of Man'' because of the huge impact humans have had on Earth during this time.

    Pleistocene

    Pleistocene
    The Pleistocene was a long ice age, it started 2.6 million years ago and ended 11,700 years ago.
  • 17 BCE

    Pliocene

    Pliocene
    The Pliocene (Pleiocene in older texts) was a short geological epoch at the end of the Neogene. It began 5.3 million years ago (mya), and ended 2.6 mya. The Pliocene follows the Miocene and is followed by the Pleistocene. The world continued to get cooler and drier in the Pliocene.

    Miocene

    Miocene
    The Miocene is the first epoch of the Neogene period of the Cainozoic. It started about 23 million years ago and ended about 5.33 million years ago. The rock beds that mark the start and end are well known, but the exact dates of the start and end of the period are uncertain
  • 15 BCE

    Oligocene

    Oligocene
    The Oligocene is the last geological epoch in the Palaeogene. It lasted for about 11 million years, from 34 mya to 23 mya. It was preceded by the Eocene and followed by the Miocene. During the Oligocene, the world continued to get cooler from its peak in the mid-Eocene. The world was still largely forested, but grasslands began to spread. Ice formed in Antarctica. The period is seen as one of transition, both in climate and in the biota.
  • 14 BCE

    Eocene

    Eocene
    The Eocene was the second geological epoch in the Palaeogene. It began 56 million years ago, and ended 33.9 million years ago. Before it was the Palaeocene and, after it, the Oligocene. The Eocene, like the Palaeocene before it, had a climate much warmer than today.
  • 13 BCE

    Paleocene

    Paleocene
    Paleocene facts for kids. The Palaeocene is the first geological epoch in the Palaeogene. It started after the end of the Cretaceous, and lasted for about 10 million years. It was followed by the Eocene epoch.
  • Period: 13 BCE to 19 BCE

    Cenozoic

    The Cenozoic Era, which began about 65 million years ago and continues into the present, is the third documented era in the history of Earth. The current locations of the continents and their modern-day inhabitants, including humans, can be traced to this period. The era began on a big down note, catching the tail end of the Cretaceous-Paleogene extinction event at the close of the Cretaceous Period that wiped out the remaining non-avian dinosaurs.
  • 12 BCE

    Cretaceous

    Cretaceous
    The Cretaceous Period started around 145.5 million years ago and ended around 65.5 million years ago. The very first flowers lived during the Cretaceous, and so did the very last dinosaurs. The earth was changing a lot during the Cretaceous.
  • 11 BCE

    Jurassic

    Jurassic
    The Jurassic Period occurred from about 199 million years ago to 145 million years ago. This was a time when the world was drastically changing as a result of what scientists call plate tectonics. ... As a result, plant and animal life became very diverse and there were many species living on land and in the water. (https://study.com/academy/lesson/jurassic-period-dinosaurs-lesson-for-kids.html)

    Triassic

    Triassic
    The Triassic is the first geological period in the Mesozoic era. It lasted 50 million years. The period began 252.17 million years ago, and ended 201.3 million years ago. The period before the Triassic was the Permian period, the last period in the Palaeozoic era. The Jurassic period came after the Triassic. Many new groups arose during the Triassic period, including the dinosaurs and the first mammals.

  • Period: 10 BCE to 12 BCE

    Mesozoic

    The Mesozoic was the geological era in which dinosaurs lived, among with other animals. It lasted around 186 million years, starting 252.2 mya (million years ago) with the P/Tr extinction and ending 66 mya with the K/T extinction (the one that killed dinosaurs).
  • 9 BCE

    Permian

    Permian
    The Permian is a geological period which started about 299 million years ago (mya), and ended about 252 mya. It is the last period of the Paleozoic era, and ended in the largest mass extinction known to science
  • 8 BCE

    Pennsylvanian

    Pennsylvanian
    The Pennsylvanian is the Upper Carboniferous epoch in the strata of North America. It comes after (above) the Mississippian, and before the Permian. The Pennsylvanian started about 323 million years ago (mya), and ended about 299 mya

    Mississippian

    Mississippian
    The Mississippian is the first geological epoch in the Carboniferous. It began about 359 million years ago (mya), and ended 323 mya. Geologists from elsewhere mostly use simply 'Carboniferous', or they use the official terms for stages, as defined by the International Commission for Stratigraphy During the Mississippian the sea level was high, and much of North America was invaded by a shallow sea. The strata consist mostly of a sequence of marine limestones.

    Devonian

    Devonian
    The Devonian is the period of the Paleozoic era from about 419 million years ago (mya) to about 359 mya. It is named after Devonshire, England, where rocks from this period were first studied. Sea levels were high, and there was a great variety of fish and other marine organisms.

    Silurian

    Silurian
    The Silurian was the first period to see macrofossils of biota on land, in the form of moss forests along lakes and streams as well as millipedes and scorpions colonizing the land later in the period. The fossil record of Sea Scorpions reached it's greatest extent in the middle silurian,about 430 million years ago.

    Ordovician

    Ordovician
    The Ordovician is the second period of the Paleozoic era. It lasted from about 485.4 million years (mya) to 443.4 mya. It follows the Cambrian period and is followed by the Silurian period. The Ordovician was named after the Welsh tribe of the Ordovices.
  • 3 BCE

    Cambrian

    Cambrian
    The Cambrian is a division of the geological time scale that belongs to the Paleozoic Era; This is divided into six periods of which the Cambrian occupies the first place preceding the Ordovician. It started about 541 million years ago, after the Proterozoic Eon and ended about 485 million years ago.
  • Period: 3 BCE to 9 BCE

    PALEOZOIC

    this time period started 541 million years ago and ended 252 million years ago.
