Sauropods are kind of from everywhere but mostly Asia and North America (as long as what Jurassic World Evolutions III has taught me is accurate). I'm wondering if there'd even had been tornados in those areas back then.

I know NA's Rockies weren't formed until like 50–60M years ago or so (same for most of today's ranges), and there were no polar ice caps as Pangea was splitting up, so air coming down "Canada" wouldn't have been frigid cold at all. I mean, they're cold-blooded reptiles with legs, but there's plenty found in Canada, even Antqrctica. So all those dinos from NA wouldn't have had tornados. The weather was probably very lush, warm, and chill, especially with all the inland shallow seas.

Would really need to check a map for the rest of them around the world in their eras, but I'm lazy. It'd be pretty easy to guess.

Edit: lol, Seropods... Sauropods* You can tell my knowledge on the Dino part here really is from JWE and that's about it.
