Happy Valentine’s Day from the Titanosaur! With a heart approximately 6 feet in circumference, this dinosaur has a lot of love to give. This sauropod’s heart likely weighed about 500 lbs (230 kg), as much as 3 grown men, and could shift 90 liters of blood with a single beat, of which there was one every 5 seconds.
