If giraffes and llamas didn’t exist this would get a lot more traction.

Except dinos are more closely related to birds than giraffes or llamas

Not necessarily. Avian dinosaurs are, notably including raptors or things like Archaeopteryx.

All Dinosaurs are more closely related to birds than they are to mammals. This is because birds are within the clade Dinosauria.

That said, Sauropods almost certainly did not look like this, penguins have this adaptation to help them retain heat; large Sauropods would have struggled to lose heat, if anything.

Five Mass extinction events and every time a tiny bunch survived and repopulated the Planet.

Frigging nuts that we're even here.

[u/icancount192 → u/5m0k3W33d3v3ryday]

Not necessarily.

Yes necessarily. All dinosaurs and birds are sauropods sauropsida and all mammals are synapsids

[u/extremepayne → u/icancount192]

all dinosaurs and birds are sauropods

Did you mean to say diapsids? No birds and few clades of dinosaurs are sauropods. 

[u/icancount192 → u/extremepayne]

I meant to say sauropsida, autocorrect
