I'm no expert myself but weren't dinosaurs cold blooded? I don't think they had a temperature mechanism that could produce a fever. Some experts....
This is just the latest headline/story in the babylonBeeification of the news.
It turns out the experts are uncertain if dinosaurs were cold blooded, warm blooded, something in between, or a mix of all three.
It is now believed dinosaurs were at least semi warmblooded with fuzzy insulation that was a precursor to feathers. Based on some evidence in rare fossilized soft tissues. They are more related to modern birds than reptiles based on molecular and structural analysis.
The chicken is ironically considered the closest living relative to the T Rex
Some evidence I read about somewhere seemed to indicate that they were warm blooded, not reptiles at all. But another search revealed the theory that they were cooler than warm but warmer than cool!
