BBC FOCUS MAGAZINE: Bird-like lungs helped dinosaurs rule the roost

Description

If you were to step into a time machine and head back to the age of the dinosaurs, you might find it a little hard to catch your breath. Back then, the Earth’s atmosphere contained much less oxygen than it does today. So how did dinosaurs manage to lead such active lives?

 

Researchers at Manchester University think they have the answer: dinosaurs had highly efficient bird-like lungs that enabled them to thrive in the harsh conditions.
