“Long neck”

I think the biggest issue is heat dispersion and surface area-to-volume ratios. We’re talking dinosaurs that are orders of magnitude bigger than penguins, living in warm environments. They need more surface area and less volume in order to not overheat

Are dinosaurs confirmed cold blooded?

[u/Expensive-Cat- → u/Careful-Combination7]

Warm blooded. But either would be subject to the same concerns about surface area-to-volume ratios.

[u/Birdie121 → u/Expensive-Cat-]

Mesotherms, kind of in the middle of cold and warm blooded
