Stupid "Science"

"But recently some scientists wondered whether the creature was too big to fly. A pair of papers recently asserted that the biggest pterosaurs may have been too heavy to get off the ground.

"That seemed implausible to Habib. After all, the biggest birds often have the longest flight range. And Quetzalcoatlus, with its 35-foot wingspan, certainly fits the bill for gigantic."

So these 35-foot-wide wings were for what, exactly?  This is like the story that according to aerodynamics theory, bumblebees can't fly.
 
Science 101: if your theory doesn't comport with reality, your theory is wrong.
