Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

If the Rock Was Bigger; the Eocene extinction event

That asteroid was only a mile wide while the one that killed the dinos was 6 miles wide.

So what would have happened if the asteroid that created the Chesapeake Crater was 6 miles wide as well? Obviously, it would cause most mammals to become extinct and would either cause a new lineage of mammals to arise or creature an avian-ruled world.

Thoughts on extinctions and what could arise?

GRAMMAR HAMMER! *create not creature*

But yes, if the thing was that big, it would make new mammals.

It wouldn't make new ones, it would cause the old ones to diversify. <_<

mammals would do a better job at surviving this kinda extinction than dinosaurs, though, AFAIK.

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

That's what I was thinking, since smaller mammals are more generalistic than the smaller dinos.

So what kind of mammals could diversify from this? Unlike the first mammal diversification, there would be no forests to hide under, so they'd have to start diversifying in the open grassland.

Hey, perhaps the multis can scratch through and not die out.

The smaller insectivores, archontans and glires should do well, but i reckon ungulates would suffer.

Yeah, I don't see ungulates making it through.

Perhaps glires could diversify and replace the ungulates?

And I could easily see the archontans evolving into some large-scale predator, competing with carnivorans (undoubtedly, the smaller ones will survive).

Talpidae could become the new species of heavily armoured slow moving grazers? Or maybe filling similar niches to bears but maybe purely nocturnal. They could create some interesting new species....

Possibly. Though I see the talpids as evolving more along the lines of anteaters, armadillos, and pangolins: large insectivores.

talpids were during eocene still a very shrew like animals,even the most basal taplids are nearly similar to soricidaes and vere relative unspecialized.If the extinction event will be too big to kill the primitive ungulates etc. they could evolve and fill many niches,from herbivores,to hypercarnivores,to filter feeding marine mammals

BTW desmans are very interesting

Actually you could see a sort of more heavily set tapir creature spawning from this...

In the end, the best advice I could give you would be to do your project in a way that feels natural to you, rather than trying to imitate some geek with a laptop in Colorado.

No sorry i meant that maybe they could evole into some sort of tapir in a couple of years. It would be cool to see something with a similar body (much larger though) but maybe a tapir like head? Could be a chief browser of more tropical climates... actually i could imagine arctic forms of these animals
