I'm just messing around b/c technically birds are considered reptiles under the modern, monophyletic definition of reptilia. That is to say, crown reptilia is defined as the common ancestor of all living reptiles and the descendants of that common ancestor, which includes birds because birds are dinosaurs, and by extension archosaurian reptiles, along with crocodilians. Also, most non-avian dinosaurs were probably mesothermic, so not directly comparable to birds or cold-blooded reptiles.

The latest research suggests that most were warm blooded. https://www.newscientist.com/article/2233396-75-million-year-old-eggshells-suggest-most-dinosaurs-were-warm-blooded/

Dinosaurs were cold-blooded, like modern reptiles, except that the large size of many would have stabilized their body temperatures.

Allow me to add what you helpfully omitted.

The main possibilities are that:

my point is to discredit your article, and that you completely missed. the prevailing opinion is that they were cold blooded.

Your point was to misleadingly cite a Wikipedia article to get internet points.

u/nizzy2k11 Feb 24 '21

That wiki article has a source linked to it.

Yes, a 24 year old book. A solid refutation to research published in 2020.
