There is an iconic scene in "Jurassic Park" when a velociraptor's breath fogs up a window as it searches for its prey. If the so-called "terrible lizards" (as "dinosauria" roughly translates to) were cold-blooded — you know, like actual lizards — this scene would have been inaccurate. Yet even though many things about the "Jurassic Park" franchise are factually questionable (not the least of which is the notion that bringing back dinosaurs from extinction is even plausible), the concept of warm-blooded dinosaurs may very well have been realistic.
At least, that is the argument of a new study published in the scientific journal Nature.
