The 500-Pound Dinosaur Heart

Season 34 Episode 11

About the Episode

Titanosaurs were the world's largest dinosaurs, weighing as much as 100 tons by some estimates. In order to push blood around such massive bodies, they needed an enormous heart. A yet-to-be named species, found in the deserts of Argentina, may have had a heart that weighed over 500 pounds and was six feet around.
