10 Recent Discoveries That Explain Prehistoric Questions Science long ago established that dinosaurs are awesome. Even though they’ve been gone for many millions of years, and left behind few mostly incomplete souvenirs of their existence, our base of knowledge of them is quite rich. However, any (seemingly) tiny discovery, at any time, can radically change our understanding of the past. 10Dinosaurs Were Neither Cold-Blooded Nor Warm-Blooded With a few exceptions, such as tuna and leatherback turtles, we’ve been drilled since childhood that animals are either distinctly cold-blooded or warm-blooded. We mammals, along with birds, are endotherms and we keep ourselves warm through metabolic processes an energetically expensive survival strategy. However, it allows us to live across a range of environments. Ectotherms, such as reptiles, have poor internal heating mechanisms they expend less energy, but suffer the inconvenience of having to sun themselves for warmth.
