Maybe… Probably more likely smaller ones…

There would be no point in walking to a cold asf region when there's so many better options. If they did exist they'd probably be very small.

Alaska wasn't too cold, it was around 30 something degrees during the. And I was referring to a hypothetical species native to Alaska

We'll have to wait and see. Alamosaurus was the only late cretaceous sauropod from North America we've found so far and it was discovered way south in New Mexico.

Dreadnoughtus, Nemegtosaurus, Opisthocoelicaudia, and Isisaurus are all from the late Cretaceous

^Mb I meant North America sauropods

Ah okay

No
