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.

Actually, that's an interesting idea: What if you had two c-shaped plates that hit each other at the points of the c, so that each was both subducting and being subducted under the other? (And yes, this isn't all that relevant to the specific Africa-Eurasia collision.)
Interesting idea, but what's in the middle of these C-shaped plates? Presumably they have now formed into an O

Without competitors, could corvids become vaguely raptor-like predators? (I don't think finches and sparrows would be considered competitors for the niche)

If global warming floods the world,will Europe became a string of islands like in the Middle to Late Cretaceous?

By raptor-like do you mean like birds of prey (eagles, hawks, falcons etc) or do you mean like dromeaosaurs or related dinosaur species (velociraptor, troodon etc). If the former, yes I see that's possible, in fact I have similar creatures in one of my projects. The latter could also happen but less likely. If you provide the right conditions and selection pressures then you should be able to acheive that

Crows are opportunistic, Crows will eat meat. The Carrion Crow has it's name for a reason, so I don't see why not. I myself have had several ideas for carnivorous crows.

Yes, I mean hawks, eagles etc. Thanks for answering my question.

Why did the Toothed birds eg. Hesperornis die out in the KT?

That bird was huge and specialised.It depended on a fish supply that collapsed temporarily and that is bad news for most aquatic animals

At that type of extinction any specialist die out.That's the tendancy during mass extinction.

Modern birds and their immediate relatives were the only birds that survived the extinction; it's doubtful having teeth or not had much to do with it. The reliance on the sea, and coast in particular, might've done in the Hesperornithiformes, although as freshwater forms exist to my knowledge it is still more complex than that. Research presented at the last SVP conference indicates Enantiornithes might've gone extinct due to a reliance on trees and forests, whereas Cretaceous relatives of modern birds were more terrestrial. So in short, all the birds that survived happened to be toothless.

Here's a relevant post on the survival of Neornithes.

What's the thing with Spinosaurus now? Do we think that it was quadruple or not?

It was almost certainly not a quadruped, and it was always rather certain, as the paper that suggested it did so in an off comment with no explanation. There are major anatomical constraints in the theropod arm and shoulder structure that make supporting weight on the forelimbs like that impossible, and although it's not impossible these could be evolved around, there's no evidence Spinosaurus did this. The idea is utter bollocks. Extraordinary claims require extraordinary evidence and all that.

As for Spinosaurus in general, we're still kind of in limbo. Since we're now fairly certain there were at least two spinosaurid taxa around in North Africa around that rough time period, it's difficult to assign the neotype specimen to Stromer's species with complete certainty. We know there was a spinosaurid with short legs (the chimera hypothesis hasn't held up), but whether it was Spinosaurus, Sigilmassasaurus, or something else remains to be seen.

If the Eromanga basin was filled in by a sea for millions of years, what would the land surrounding the basin at the coast be? Would it just be desert or could the sea support woodland environments like mangrove forests for example?
