I was interested in the claim that it is warm-blooded (based on your quote). I went to the article and the link associated with the term 'warm-blooded' leads to an article that makes absolutely no mention of warm-bloodedness or thermoregulation. As such, I'm not going to put much faith in the article.

Here is the possible source of that claim https://onlinelibrary.wiley.com/doi/10.1111/pala.12240

It seems it is not a matter of settled science however at least from skimming that paper. Not any kind of palaeontologist but I do like dinosaurs like any sensible person.
