It was concluded long ago that probably only the earliest dinosaurs were cold-blooded. Most of them show signs of being warm-blooded after all and some smaller ones were found with signs of having primitive feathers.
my understanding is birds evolved from certain orders of dinosaurs, which share similar body structure.
A lot of people don't realize that the earliest dinosaurs went extinct while the newer ones came on.
The dinosaur era lasted many millions of years, and it is likely that they were similar but not the same.
