While the world today is diverse with all forms of life, nobody knows when the next catastrophe will strike. An extinction event on the same level as the extinctions in the Permian and Cretaceous time periods can lead to the extinction of the majority of species on Earth. Life on Earth after a mass extinction event is not diverse, creating a kind of "Clean Slate" for the evolution process.
The Holocene Extinction Event Edit
At the end of the Holocene era, a giant asteroid (8 miles wide) impacted Earth's South Pacific. The asteroid impacted the coast of Indonesia and caused a surge in seismic activity, including giant tsunamis and volcanic activity. The majority of life on Earth were now extinct, including humans. Megafauna such as giraffes, elephants, and rhinos were completely extinct, along with any animal larger than a horse. Plant life was on the decline as well, with the majority of large foliage rendered extinct. The combination of the asteroid and the surge of seismic activity plunged Earth into an age of darkness, which would last about 10 million years.
The Dawn of The Aureacene Edit
10 million years after the Holocene mass extinction event, the world was now in an era known as the Aureacene ("Golden Age"). This era gets it's name from the surge of biodiversity across the planet, which was now home to a host of new strange and unique creatures. Several major groups of animals have survived the Holocene mass extinction such as:
- Rodents and Lagomorphs
- Some Felines and Canines
- Small Marsupials
- Small Ungulates
- Mustelids and Bats
- Some Reptiles and Amphibians
- Some Flightless Birds
- Small Raptors and Seabirds
- Some Songbirds and Tropical Birds
- Insects and Arachnids
- Some Mollusks
- Some Fish and Small Sharks
The Aureacene has a vast diversity of plants and animals specifically adapted to a tropical world. The animals that survived the mass extinction branched out to form new and unique species that are well-suited to fill the niches left behind by the fauna of the Holocene.
