Dinosaurus were suggested to be warm blooded

Hm. I thought scientists found out that they were a mix of warm and cold blooded.

What a lot of people forget when they think "birds are descendants of dinosaurs" is that not all dinosaurs were birds' ancestors.  Only the dromaeosaurs and maybe other ceolurosaurs, but not ceratopsians or sauropods.  So this article should have only mentioned the ceolurosaurs.  We have no idea about any other dinosaurs at all.
