Amazing Dinosaur Invention: The Bone-Lung!

It appears that dinosaurs (or some dinosaurs) may have had air sacs in their bones, allowing them to circulate the air they breathed into their bones and then back into their lungs again, giving them an extra-efficient breathing system and allowing them to sustain the hot-blooded metabolism that many scientists now think they had.

Turns out, while dinos may have invented this system of utilizing air, they aren’t the only creatures that are known to use it.

Another, very common kind of critter also uses it . . . birds.

GET THE STORY.
