The frozen mammoths we found were intact because the area had stayed frozen since the animal died. So no freeze/thaw cycles.

However, dinosaurs are much much older than mammoths. Mammoths were hunted by the earliest humans, so not that long ago.

I don't know if there's any spot on earth that hasn't thawed at some point since the dinosaurs roamed. Even Antarctica at one point had forests (and it also wasn't always at the south pole).

It doesn’t.

The video doesn’t have anything to do with it either. It’s just a separate video where Cooper talks to a guy about dinosaurs.

They stuck it at the top of the article hoping people would think it’s relevant and click on it.

I don't like how it describes birds as merely "descendants" of dinosaurs.

All major bird groups evolved several millions years before the mass extinction event, not after. Animals like ducks and herons would have been right a home in a picture that also contained Tyrannosaurs or other cretaceous non-avian dinosaurs.

Its a pretty common misconception that birds evolved from surviving dinosaurs, but what birds actually are is a relatively new clade of theropods that evolved just before the extinction event and had already significantly diversified already into many niches by the time of it.
