Long-neck dinosaurs likely had swan-like posture

Typically, long-necked dinosaurs (sauropods) are shown in museums and text books with their necks bent at a 45-degree angle. But "this view of sauropods is simply incorrect, based on everything we know about living animals." (Cosmos)

More likely, sauropods stood with a "swan-like 's' curve" to their necks, heads held high.

The only catch is the blood pressure needed to pull this off. "The blood pressures, and hence heart sizes, required are quite large."

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
