The 500-Pound Dinosaur Heart
Clip: Season 34 Episode 11 | 1m 14sVideo has Closed Captions
The heart of a newly-discovered dinosaur may have weighed as much as a grizzly bear.
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.
