Anyway here's some more periods of ancient time.
1. Kleptocene Epoch.
Also known as the Ten Million Years of Crime. Began when a previously harmless species of cyanobacteria figured out how to run a protection racket, demanding a greater slice of the ecosystem in exchange for not evolving to massively overproduce oxygen and devastate the global climate. Competition swiftly lead to the domination of the biosphere by brutal interspecies cartels that survived by shaking each other down - like, nice reproductive strategy you got there. Be a shame if some more efficient species started competing with you for nesting sites. Hey, are you using this migration route, because my wife has one just like it at home. The execution of a prominent genus of arboreal herbivore by a species of flowering plant that spent four hundred thousand years insinuating itself into an enemy cartel before suddenly and deliberately losing all its nutritional value sparked a gang war that wiped out 90% of all species on the globe, leaving behind only a few random strands of criminal DNA.
2. Carnocene Epoch.
Triggered by a sudden, unexplained mass extinction among the bacteria responsible for decomposition. Unrotting corpses piled up in mountains, fresh as the day they were killed except for a few bite marks. Scavengers and obligate carnivores grew fat and gigantic on the endless, risk-free food supply, wading knee-high through fields of jagged bone and clotted blood. Jungles became sunless fortresses of fallen trees, wastelands where nothing could reach the soil or the sky. Sea levels rose as leviathan corpses piled up on the ocean floor, home to civilizations of crawling pale crabs. Theologians argue that God brought this age about as punishment for the first murder, so that the body of the first victim could never be hidden. It's not clear if humans had evolved yet but that doesn't stop them.
3. Turbozoic Era.
Characterised by a massive acceleration in tectonic activity, with mountain ranges throwing themselves up overnight and continents chasing each other around the equator like Benny Hill. Ease of intercontinental contact led to the development of a thriving heterogeneous global economy among the insect people of the time, though the difficulty of stable farming kept technology primitive and populations low. First sapient volcanoes.
4. The Age When Bacteria Were Big And Animals Were Small.
Self-explanatory.
5. Svabhavan Glaciation.
Continents seeded with organic superconductors, rearranged into a single vast circuit and cooled to near-absolute zero by a hyperevolved race of yeti seeking to transform the planet into a huge computer and use its superior brain power to achieve absolute enlightenment. The computer either sublimated them into a higher dimension or killed them all and committed suicide, depending on who you ask. The planet was left to warm back up over a period of hundreds of millions of years. Multicellular life basically had to start from scratch, and the oldest sapient volcanoes are said to still be angry about it. Samples of life from before that time are preserved in hidden yeti cryovaults, guarded by terrible electronic sentinels, possibly.
6. Groovy Age.
Dominated by a phylum of fungi that released psychoactive chemicals into the atmosphere as part of their respiratory cycle, making everything very chill and relaxed. The pressure of evolutionary competition weakened as major species of carnivore began to wonder why everyone needed to be so aggressive all the time, leading to the development of herbivores goofy enough to fall backward into their open mouths. A mass extinction event was averted by the advent of fungus-eating "cop beetles", which is still gleefully cited as an example by conservatives everywhere.
7. Bird Age.
Everything was birds. Trees? Tall birds. Viruses? Small birds. Rocks? Heavy birds. People were pretty happy to see the end of this one.
8. Tartarocene Epoch.
Herd animals began to evolve hells as punishment for antisocial behaviour, leading to a population boom as they became increasingly co-operative and disinclined to masturbate. Pack hunters copied the practice, piggy-backing on equine and bovine hells instead of developing their own. A couple of species flirted with heavens but found them ineffective as a motivator. Over time the hells became more painful and horrible as species sought to outdo each other, and whole ecosystems sprung up around it - parasites without afterlives who could physically drain the sin from your body, inquisitor alphas who exiled sinners from the flock before they could corrupt the youth, temptresses who guided rival species into depravity in exchange for a kickback from the demons. Fossils from this epoch have a tendency to look very frightened.
9. Second Bird Age.
God damn it.
10. Oneirocene Epoch.
The "dreamtime period" when animals took on, and retroactively had always possessed, human form, and went around doing fairytale stuff like stealing each other's tails and accidentally creating the world from a grain of sand. Setting of all mythological origin stories. Brought all other epochs into existence and also was brought into existence by them. A fringe group of researchers argue that this epoch never happened, and was invented by fuzzy-minded fabulists as a way to reconcile the gulf between hard science and the foolish obsolete superstitions of a less rational age, but those guys are wrong.
