Did sauropods have multiple hearts?

So far as researchers have been able to discern, sauropods did not have accessory hearts or a special siphon system to help them circulate blood.

How many hearts did sauropods have?

Such an enormous pressure would require a very large, strong and slow-beating heart. But, they postulate, instead of a single large heart, the Barosaurus probably had some eight hearts.

How did sauropods get blood to their heads?

In sauropods, as the cervical ribs flexed, they would have compressed towards the neck, and the muscle would have pushed on air sacs wrapped around the vertebral artery. In effect, the motion “acts as an accessory pump to the heart,” says Habib.

Are there any complete specimens of the sauropod?

Sauropods are one of the most recognizable groups of dinosaurs, and have become a fixture in popular culture due to their impressive size. Complete sauropod fossil finds are rare. Many species, especially the largest, are known only from isolated and disarticulated bones. Many near-complete specimens lack heads, tail tips and limbs.

How big was the neck of a sauropod?

University of Southern California paleontologist Michael Habib was inspired to investigate sauropod necks after seeing bones from a giant titanosaur found in the New Mexico desert. The well-preserved neck bones included spines called cervical ribs that stretch almost six feet long.

How did sauropods pump blood to their brains?

In sauropods, as the cervical ribs flexed, they would have compressed towards the neck, and the muscle would have pushed on air sacs wrapped around the vertebral artery. In effect, the motion “acts as an accessory pump to the heart,” says Habib. The typical skeletal structures of sauropod necks; colored bars represent length in meters.
