Which large extant predator would fare best in a late jurassic setting? I don't know. My wildcard would be lions, they are modestly large in size and good pack hunters, which will be essential in survival against bigger dinosaurs. If you include marine animals, probably killer whales. How would deinosuchus (8 meter, 2.5 tonne) crocodile do in Africa today? What would it prey upon?Next person go ahead, lol.

They could prey on small enough hippos and rhinos and hunt bigger prey than the Nile crocodiles they will coexist with.
How would cheetahs fare in Maastrichtian western North America?

Probably fairly well, as a hunter of small ornithopods. Its running speed would probably allow it to develope its own niche, compared to dromaeosaurids which wheren’t really that fast and would have relied on completely different hunting tactics.
What is the largest prey a pack of wolves (of a number that occurs in the wild) could realistically take?

How would survive an adult Sarcosuchus in the place of Gustave in the actual Lake Tanganyika ?
Gustave is a feared survivor there showing scars from gunshots and never successfully captured...

I think the bovines they already hunt are possibly the limit. Assuming a Sarcosuchus could find enough food, I think it could hunt large fish and possibly hippos.
How would T.rex fare in the Pleistocene of North America (assume it got over the cold climate thing, possibly having a thick enough coat of feathers)?

What if a lion pride tried to attack a giraffe from the trees?

Correct me if I'm wrong, but wouldn't t.Rex be used to a higher amount of oxygen? Other than that, I think it can try to go after larger prey. The biggest problem is trying to ambush, because it's so big and slow, it makes it difficult to hide and I don't know about it's endurance.

A T.rex in the 4-6t ballpark was probably able to run at 25 mph, I'm guessing Sue was more in the 18 mph range. Given elephants (thus applying that to mammoths and mastodons who are nearly or equal in size to T.rex) apparently aren't that fast, speed isn't an issue to me.

Is T.rex use to more of it? If the T.rex needed to ambush, its has no where to hide. As soon as a herd spots a t.rex coming, they'll start running. Elephants run at about 25 miles per hour. Because it would have a hard time ambushing and catching, and because there is too many things unclear. I don't see the future being too bright.

(home to other giant killers, i.e. carcharodontosaurus, spinosaurus, etc.)

Not 100% sure. IIRC, the Pleistocene of NA had more forests and the likes for ambush predators (ie: Smilodon). Not saying T.rex will utilize it, but just saying that "nowhere to hide" isn't exactly accurate. Again, not exactly. carnivoraforum.com/single/?p=8587378&t=9892394Carcharadon, not sure if there's the right prey for T.rex in Cenomanian Africa.

Juvenile paralititan?

Probably, but I have a feeling there should be more to its diet.
I just came up with juvenile spinosaurs or giant fish carcasses. Other than that (and possibly Ouranosaurus) I can't think of much more.

Wait, there's also aegyptosaurus.

Oxygen levels in the Mesozoic were nearly identical to modern day levels, but the late Cretaceous had the biggest gap ~30% higher than today. I see the rex breathing heavily, and not being very healthy, but able to survive.
