    Most mammals of this time started to take on their modern day appareances, while more primitive mammals became extinct. Diversity amongst mammals reached its peak in the Miocene Epoch. Deer, giraffes, and hyenas began to appear, and the sabre-toothed tiger was the dominant predator. In the oceans, there was a plethora of whales, dugongs, corals, gastropods and echinoids.

    5 Million Years Ago - Pliocene Epoch

    5 Million Years Ago - Pliocene Epoch
    Mammals such as cattle, goats, antelope, gazelle, and sheep begin to dominate the Pilocene. Rodents remain abundant as well. As these animals increase, animals that have been common up until this point such as rhinoceroses, elephants, and camels, are starting to reduce. Another mammal of this time was the Macrauchenia, which was the member of an extrinct group of mammals called Litopterns. An important mammal that developed around this time were primates, which also includes early humans.

    1.8 Million Years Ago - Pleistocene Epoch

    1.8 Million Years Ago - Pleistocene Epoch
    The Pleistocene Epoch was during the time of the Ice Ages, where massive ice sheets extended towards the equator from the Antarctic and Acrtic regions which ended up covering most of Europe and North America and ended around 10,000 years ago. Many mammals went extinct around this time, especially larger sized animals such as the Woolly Mammoth, giant dear, and cave bears.
  • 10,000 Years Ago - Holocene Epoch

    10,000 Years Ago - Holocene Epoch
    The Holocene Epoch began 10,000 years ago since the end of the last Ice Age and it is the epoch we currently live in with modern humans, animals, science, and technology. Now we can only see where we will all be taken next.
