Jack Horner needs to watch this!

I know this can be hard to quantify, but how intelligent were Tyrannosaurs, compared to modern animals? I'm especially thinking in comparison to mammals and birds that do hunting.

@Albukhshi I'd guess there's no way of knowing, short of finding out that Tyrannosaurus had a civilization. I think what Dr. Currie is getting at here is that some dinosaurs, mainly tyrannosaurids, developed abilities we heretofore only associated with modern animals, such as wolves and orcas. T-rex probably had the largest brain of any known animal up to that time, and for a good many millions of years afterwards.

I'm not looking for exact figures-which as you pointed out, is impossible. & I do understand the main point of the clip-yes, Tyrannosaurids were pretty smart. what I want to know is: is it possible to get an idea of the relative intelligence of the animal. is it as smart, or not as smart, etc, compared to the aforementioned?

I know that part is partially possible-since other clips talk about relative intelligence of Hyaenodonts to modern mammalian predators. (they weren't as intelligent).
