Pretty sure a Paleoloxodon namadicus would give a T. Rex a run for its money though.

Simple question: How exactly would you design the food web for the Wessex formation or Chinle?

Also, Austroraptor or Megaraptor as the top predator in Turonian Argentina?

Austroraptor is from the Maastrichtian, dude! xD

Oh yeah. I saw something that showed Megaraptor and Austroraptor living at the same time. Pretty sure it's Orkoraptor that lived alongside the king of that book series I'm writing (and by book I mean fan fiction)

Austroraptor ---> 70 million years ago

Megaraptor ---> 91 - 88 million years ago

So, they pretty much has been seperated in time for longer than Homo sapiens has been around on earth... Megaraptor did coexist with smaller cousin of Austro like Unenlagia though.

And Austroraptor is roughly concurrent (though not really at the same place) with Orkoraptor, one would expect there to be at least one species of megaraptoran near it

So Austroraptor vs Orkoraptor.

There wouldn't be any VS, Austrotaptor is basically a giant heron while Orkoraptor is a big game hunter, so there would be very little competition over food and likely space aswell.

I wouldn't expect Austroraptor to do anything much other than trying to flee. Its slender jaws and super tiny teeth indicates that it wasn't born to hunt big, strong prey, not to mention its legs which seem to be longer in proportion than any other macropredator dromaeosaurs. Although, I haven't seen any paper about it, the most acceptable theory right now is that most Unenlagiine, including Austroraptor probably actively hunt like today wading bird, eating fish, amphibians and other small reptiles they come across.

Megaraptor and its kin are on the other hand, a fast running predator armed with large sickle claws on its hands and they are like 6+ metres.... The question here should be "How often would any Megaraptorid consider Austroraptor as lunch."

Is it plausible that some dinosaurs (perhaps large ones that lived in hot climates) may have had large areas of bare skin as opposed to either feathers or scales?

Very plausible. We actually have evidence for this in Ornithomimids. The only thing is it would have to be on the underside of the animal or else very darkly coloured, to prevent sunburn.

Could've sworn I read somewhere that we have bare skin impressions from Gorgosaurus as well.

Is it likely for Ankylosaurus to frequent swamps and wet areas?

Hello! I am new to the feathers on dinosaurs and wanted to know that dinosaurs had feathers? and which probably no? :)

We can at least say with relative certainty that feathers are basal to all coelurosaurs (the theropod group that includes maniraptorans, tyrannosauroids, compsognathids, ornithomimosaurs, etc.). Some ornithischians also had quills and soft filaments that are probably related in some form to the feathers of theropods. Likewise, we can be pretty certain that scales were present on iguanodontians, ceratosaurians, and large sauropods. Outside of those, it's pretty much up to speculation as to what is and isn't feathered.
