Seems strange considering their frequency in the sol system…

The 6th chapter.
Chapter 6: The Midkernian lifeforms.
Later in the Midkernian epoch (1.4 bya), multicelluar organisms got bigger and bigger, as they got bigger, they diverged into 4 distinct body plans. These 4 body plans are what will be the backbones of all animal life after this period.

Protomagnobalia (first-big-ball) is a clade that is mostly a circle, there’s one opening that is used for ingestion, egestion and reproduction. They broadcast spawn, meaning that they mass-procude eggs in the chance that they contct each other and make offspring.

Pseudopsaria (false-fish) is another clade that bear a primitive fish-like body plan to swim, they have no teeth and broadcast spawn once a month.

Argizoa (slow-animal) is one of the sessile clades, the body it covered by a shell made of calcium carbonate, the opening is surrounded by thin tentacles. They live in the epipelagic to the bathypelagic.

Paraargizoa (different-slow-animal) is the second sessile clade, it looks like a sponge, it lives in the deep sea, so it’s color is black and it feeds of off the black smokers.


The body plans.

I see there’ll be 3 ages in total?

Yes, the biggest timespan in chronology is the eon, not the age.

Btw why is the middle archeohycean the first period of that age? Shouldn’t it be “early”?

Maybe it’s a quirk how I name the periods.

I suppose so. Seeing the usage of “bya” I presume we won’t go beyond “0 bya”?

bya is an acronym for a “billion years ago”, if it’s lower than 1, I won’t use bya.

Btw is this bya from our present or the present of some sapient species that’ll emerge on hycaea?

I am assuming for the sake of simplicity, you won’t include Eras in your timeline?Geologic time scale - Wikipedia

I mean maybe at some point it will zoom in on the timeline for eras to have enough space to be readable there?

No, the Archeohycean is an era.

I see. By the way, I presume you have planned this project pretty far into the future by now, right?

I don’t know but here’s a chapter.

Chapter 7: Diversification
hye
The Sebyan period and the Solohycean era begins as clades begin a diversification explosion due to the predation cycle and several other factors. This explosion is called the Sebyan Diversification Explosion, named after Terry Sebya.

The clades
As a consequence to the S.D.E., the Protomagnobalia begin to split into 2 clades, the open sea loving Magnobalia and the shelled Conchobalia.

Magnobalia is the open sea branch of Protomagnobalia, they’re small and became diggers due to the predators that are called Anomalopsaria. They dig to bury themselves into the sand.
Conchobalia differs from Magnobalia on how to prevent dying from predators, the clade is shelled, meaning they can’t be eaten by early Anomalopsaria.

However they may evolve sharp teeth which breaks the Conchobalia’s shell and thus they can be eaten.

The Pseudopsaria split into the predatory and herbivorous counterparts, the Anomalopsaria and Phytophagapsaria.

Anomalopsaria is a carnivorous clade that eats on magnobalids and conchobalids, they use several forms of eating their prey since their clade is very diverse and chock full of genuses. One of them is teeth, they use them to crush shells and chew their prey.
Phytophagapsaria is the herbivorous counterpart to Anomalopsaria, they eat purple kelp and sea grass. They resort to size as a defense against carnivores.

Argizoa insignificantly diversified during the S.D.E. they slowly evolved , such as Soloazoa and Collectozoa, Soloazoa mostly fed on plankton and Collectozoa made clumps of themselves to reproduce.

Paraargizoa eveolved into Hunderia and Abyssohunderia, they’re the family of hunderts. The former lives in the open sea and is sessile, the latter lives in the abyss, it is black and feed off of volcanic vents.

How do people have so much knowledge about the planet’s past? From fossil record I presume?
