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.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

Birdless world; stronger K-T

Dinosaurs eat man, woman inherits the Earth.

65 million years ago, an asteroid struck Earth and wiped out a good percentage of life on the planet.

Among the extinct were all dinosaurs (save for birds), all air reptiles, all marine reptiles, and a few groups I forgot to mention (I'm not a paleontologist, so if someone were to name all the groups that went extinct, I'd be grateful).



Anyway, what I was wondering was: what if the asteroid had been slightly larger? Large enough to count the birds among those forever buried in the fossil record.

What would the post K-T world be like without birds?

Discuss ideas and possible creatures.


P.S. If you're interested in turning this into an actual project, let me know.

Mesonychians live on in the whales, don't they?
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.

Yes, though considering whales diverged very early they almost don't count

Back on the subject of flying marsupials do you think they would evolve to look something like a bat by convergent evolution.

Close, probably. The same, i doubt it.

Your all insane And I won't be posting soon as my founded crys about the poles are falling on deaf ears(or would that be eyes?) but I will point you towards the new spec evo topic by a member here for some reference and JohnFaa saying stuff about you all(Mwuahahahahahahahahahah!).

Excuse me, folks, I haven't read the whole topic, so I'm giving a quick reply after reading the topic title.

If no bird has evolved (or gone extinct before time), I'd think the niche could be occupied by mammals.

An unclear finding at Crato basin (Cretaceous, Brasil), I'm not sure about the fossilsite, would hint the presence of insectivoran-like either "bat-like" mammal inferred by some teeth.

Anyway, I reckon avian niche being occupied by gliding and then flying mammals.

Either much simply by Dinosaurs themselves. Feathered maniraptorans and other theropods could have been suitable candidates

Do you mean Argentoconodon, the supposed late Cretaceous volaticothere relative that might had been volant?

If birds hadn't evolved at all, I give you a clue for what group of animals that would take their place. They were sauropsids, but not dinosaurs. They had membranous wings, but were very unlike those of bats. Some had beaks, others teeth.

In case you haven't figured out, thats the pterosaurs. Except an alternate world's Messel to be filled with fossils of various forms of pterosaurs, from Darwinopterus like forms to huge azhdarchids and ornithocheiroids

Likely, but if topic starter assumes a "stronger" KT, maybe even pterosaurs could have gone extinct.

After ATEK Azul went off about not many people paying attention to the polar regions problem I starting thinking of what would be at the polar regions although it is a bit late. I remember JohnFaa mentioning mammals with feather like structures before, I haven't come up with any thing yet though.

Thank you for paying attention and I hope you resolve it. :)

It wouldn't be anything drastically different to modern polar mammals.
