Are there any sauropods confirmed to live in extremely cold climate?

There's an unnamed titanosaur from Antarctica IIRC.

When was it from? Antarctica was not always freezing.

It wasn't always freezing, but even during the Mesozoic it wasn't exactly tropical. The polar regions still had fairly cold winters back then.

it wasn't always even a polar region tho
when it was it was comparable to Japan/New Zealand/Northern USA/Canada for climate


tupandactylus using its crest to hit smaller pterosaurs
not ramming them or something insane like that, but using it to try and block/bully them like a frigate bird -esq behavior

Well this titanosaur's remains were dated to the mid or late Cretaceous IIRC, during a time when Antarctica WAS a polar region and got to below freezing temperatures in the winters.

would Antarctica have been large enough to warrant seasonal migrations to warmer regions? or would it have all been uniform?

I would say this would be unlikely, Tupandactylus and co. weren't exactly great fliers and had stubby wings, so if they tried to bully a smaller Pterosaur, it could more than likely just fly faster or dart out of the way.

Thank you for your response Jurassic MT, that answer seems right to me too.

Another question I came up with is in regards to how some predatory dinosaurs may have raised their young. I recently came across a documentary about harpy eagles (https://www.youtube.com/watch?v=WuA5yc3nHHM) and it is mentioned roughly between 53 - 54:10 minutes in that the eagle parents may have left the prey near the nest mostly untouched (in favor of prey further out in their territory) so that older chicks may observe these prey items while still being supported by the parents. Would it be possible for some predatory dinosaurs like tyrannosaurus, etc. to use similar techniques?

Theoretically, could there be a dinosaur that actually spat a sort of blinding toxin, like the JP Dilo?

Not in the way JP Dilophosaurus could. At most, I'd say it's possible that dinosaurs could secrete some form of substance if they have evolved required glands, but I'm not sure how strong could the substance be or how would they launch it.

AFAIK modern archosaurs don't have much saliva, which it's what venom evolved from.
But I can easily see some dinosaurs spitting Puke on an attacker as a defense, like some modern birds.

Here's an idea: A predator, like Dilophosaurus, having a throat pouch that allows them to store materials (puke, rotting carrion, your pick) to either repel competition, or perhaps to mark their territory, like the way wolves do with urine.

Talk about urine... Do you think dinosaurs urinate in the form of liquid or solid? Many birds today has solid form of urine, except ratites like ostrich which do it in liquid form.
