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.

Maniraptora radiation; speculative forms of maniraptora; are they plausible?

Maniraptora are bird-like dinosaurs, as all of you know. They have a lot of chance at surviving and a lot of potential. I'm thinking they'd probably survive the Eocene-Oligocene cooloff and maybe fill niches emptied by extinction?
My dinosaur project(on my wikidot site) has a lot of different maniraptora dinosaurs, although they are yet to be written down. I have large quadruped browsers, some tree-climbing ones with a monkey lifestyle, fish eaters and some large carnivorous tyrannosaur-like ones.
Well how would maniraptora really evolve with no K-T? I'm open to suggestions

quadruped sauropod-like forms or large ratite-like forms, which has more advantages? I'm thinking therizinosaurs would become large browsers, since they were already browsers at the end of Cretaceous. Or maybe even troodonts or alvarezsaurs?

i dont think that they could evolve into quadrapedal sauropod like formes,more likeli is ratite like forms.

How about false tyranosaurus?just tyranosaurus like maniraptor(with beak and feathers :P)

Depends how they survive which governs the survival of the others.

But tree-climbing will definitely be hard for theropod shoulders...

Maniraptora WOULD NOT evolve into dinosauroids. I must make that clear. They would probably maintain a similiar body plan, but maybe more weaponisation would occur?
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.

he said that he have no ssapient species in his project

there is some arboreal maniraptors in spec too

How do they explain the arboreal ones?

I think arboreal ones are possible if they evolve more flexible wrists capable of rotation

Scansoriopteryx was probably arboreal.

About tyrannosaur-like ones, I have a gigantic oviraptorosaur with a tyrannosaur-like lifestlye. Plus I added the oviraptorosaur page on my site, although it's not finished. Are browsing oviraptorosaurs plausible?

And yesterday I saw povorot had tyrannosaur-like dromaeosaurs. One like a tyrannosaur and the other like an abelisaur

i think that niche would be mor elikeli taken by therizinosaurs

Yes, but animals like that are going to be more birdy and glide-y.

But hey, nothing will stop some of them from evolving into arboreal forms, since those niches will be open to exploitation. Maybe some could even evolve into fruigivorous or insectivorous animals.
Are partially arboreal hypercarnivorous dromaeosaurs possible? like some tree-climbing big cats we have.

Aniamls like microraptor are more likely to spawn arboreals in addition to bird forms, i think.

Yeah that's very likely. :D microraptors were animals especially adapted to tree life, so if flight wasn't necessary they'd just rather become flightless and arboreal. I mean microraptor glided tree from tree, but I think in dense canopies arboreal forms will be more efficient
