Flying Giraffes

You look up and see a creature about the size of a giraffe with a wingspan twice as long as its tall.  That was Quetzalcoatlus and was one of the biggest type of azdarchidae pterosaurs ever to live.  It makes me wonder how it could have flown with the necessary thrust necessary to get off the ground it would need to blow approximately two tons of air with every stroke.  That's one strong chest!  It had to have been warm blooded to keep up that much energy but really could it have that much power?

For several decades the dominant theory that killed the dinosaurs the earth was hit by a giant meteor in the Chixulub peninsula in Central America today.  There is a worldwide thick layer of iridium in this geological stratum where the Cretaceous (when the dinosaurs died out) meets the Tertiary boundary.  Iridium is a very rare mineral on Earth but in meteors its common.  Finding an iridium layer is evidence of a meteor strike. 

Recently there have been conflicting theories that perhaps it wasn't just a meteor.   Theories like types of dinosaurs were already dwindling (a favorite of my historical geology professor), there was already massive volcano eruptions and we were possibly going through a cyclical million year plus intergalactic cloud might have been all factors in the end of the Dinosaurs. 

With the discovery of a oddly elliptical new planet that is being described as a possible dwarf star this could have brought an interstellar cloud of meteors and gravitational disruptions for thousands possibly millions of years.  Ancient civilizations like the Mayans predict a very long galactic cycle that points to larger factors that were known and recorded by our predecessors. 

Could the flying giraffe Quetzacoatlus who lived in the late Creataceous evolved in an environment of turbulent winds brought on by the impending death of the Dinosaurs?  It might have made their flying easier if there were winds that constantly buffetted the earth.  Even seen in our solar system Jupiter's Red Eye storm has lasted over 400 years and continues to rage across its surface.  The storm itself is the size of approximately three earths. Could the earth's environment propelled the flying giraffe?

When I look up today I wonder if the birds are getting bigger and flying easier.
