This is thread for the end-Devonian extinction.

How about a big extinction of Cephalostians?

I reckon they're one of the best placed to survive. But an ocean change could do them harm.

How about a complete extinction of Lucivermia?

Sure, Lucivermia can go.

A lot of the larger cephalostians, like death-stars, would go extinct. There would probably be a die-back in Neospoggia forest, but I think they would eventually come back, other types of Neosoggia could go extinct. Star-cows would finally go extinct. Land and freshwater ecosystems would be less harmed wit probably only the bigger, less adaptable species dying out.

Plants may have of helped cause the extinction in HE, would RE plants affect the globe differently?

I was going to suggest the star-cows but I wasn't sure of them since they were submitted in the Silurian.

They made it into the Devonian but were on their way out due to competition with more advanced cephalostians.

As for plants: HE had significant forests by the end of the Devonian; RE's plants don't lend themselves to tree forms (at least not as of the Devonian) -- the closest are the rope trees, and they top out at like 1.5 meters -- so real forests don't exist. So it'd probably be very different.

I figure the land ecosystems will be more analogous to modern grasslands than forests, with fast-growing, short-lifespan plants and a lack of stratification (as in complex forests with canopy/understory etc.)


Star-cows and the bigger cephalostians going extinct makes sense.

Neospoggia forests should recover, I had those planned to die off in the end-Permian.

I would like the podplants and rope-trees to survive, as those look promising for future developments in the flora.

Hmm. So so far...

Totally extinct: Lucivermia.

Hard hit: Many marine cephalostia (death stars, star-cows, etc). Non-forest/reef building Neospoggia.

Would sea-kites survive? I assume it would go extinct.

Also, when are starting on the Carboniferous?

I'm skeptical on Sea Kites. After all they are only 1 meter big and eat cnidarians and plankton, although the larger 2.5 meter ones should go extinct.

Yeah, when will we start the Carboniferous?

I guess we can start the Carboniferous now, if we're satisfied with these being the groups that go extinct; looks good to me.

OK, so finalized, I guess:

Totally extinct: Lucivermia.

Hard hit: Many marine cephalostia, especially large ones (death stars, star-cows, largest sea kites...) Non-forest/reef building Neospoggia.
