ON THE SIZE AND FLIGHT DIVERSITY OF GIANT PTEROSAURS, THE USE OF BIRDS AS PTEROSAURS ANALOGUES AND COMMENTS ON PTEROSAURS FLIGHTLESSNESS
http://www.plosone.org/article/info%3Adoi%2F1...

The size and flight mechanics of giant pterosaurs have received considerable research interest for the last century but are confused by conflicting interpretations of pterosaur biology and flight capabilities. Avian biomechanical parameters have often been applied to pterosaurs in such research but, due to considerable differences in avian and pterosaur anatomy, have lead to systematic errors interpreting pterosaur flight mechanics. Such assumptions have lead to assertions that giant pterosaurs were extremely lightweight to facilitate flight or, if more realistic masses are assumed, were flightless. Reappraisal of the proportions, scaling and morphology of giant pterosaur fossils suggests that bird and pterosaur wing structure, gross anatomy and launch kinematics are too different to be considered mechanically interchangeable. Conclusions assuming such interchangeability—including those indicating that giant pterosaurs were flightless—are found to be based on inaccurate and poorly supported assumptions of structural scaling and launch kinematics. Pterosaur bone strength and flap-gliding performance demonstrate that giant pterosaur anatomy was capable of generating sufficient lift and thrust for powered flight as well as resisting flight loading stresses. The retention of flight characteristics across giant pterosaur skeletons and their considerable robustness compared to similarly-massed terrestrial animals suggest that giant pterosaurs were not flightless. Moreover, the term ‘giant pterosaur’ includes at least two radically different forms with very distinct palaeoecological signatures and, accordingly, all but the most basic sweeping conclusions about giant pterosaur flight should be treated with caution. Reappraisal of giant pterosaur material also reveals that the size of the largest pterosaurs, previously suggested to have wingspans up to 13 m and masses up to 544 kg, have been overestimated. Scaling of fragmentary giant pterosaur remains have been misled by distorted fossils or used inappropriate scaling techniques, indicating that 10–11 m wingspans and masses of 200–250 kg are the most reliable upper estimates of known pterosaur size.

Giant pterosaurs could fly. Yes indeed.

However a much smaller one was flightless. See it here.

Oh Lawd, if Al were here... I dun even... he wouldn't be happy, I can tell you that. I have nether the wit nor the knowledge to go into a taxonomix/phylogenetic/methodo logical debate with you, but I will say this good sir: Your method is screwed up. Publish or it didn't happen.

On the other hand, welcome to the Topix community! You'll find it is mainly populated by children who like to debate which dinosaur was bigger/better, but there are glimmers of intelligence. Hope for you to participate in many discussions!

Exactly. And man i miss Big Al, but any way, still can you name the Ptreosaur???? Or show me an actual scientific document.

AND I AM INTELLIGENT! WHAT OTHER TEN YEAR OLD THAT YOU KNOW, KNOWS ALL 118 ELEMENTS OF THE PERIODIC TABLE, THE ATOMIC WEIGHT OF BERYLLIUM, AND HASAN I.Q. OF 142?!?!?!?!?!

Lol spelling error. But, when you post in all caps, it's hard to tell the difference.

While you certainly seem brighter than the current generation the board has attracted, IMO memorization doesn't count for shit. But your IQ is impressive, so kudos.

According to his blog, which for all its errors is actually a pretty good read, its a species of Pterodactylus (longicillum, I believe). This guy, David Peters, is rather infamous among pterosaur researchers, you can read the full story (and his response) here: http://paleoking.blogspot.com/2011/05/strange...

I think it more likely 142 is his credit score. His IQ is probably equal to the circumference of his head measured horizontally, ears and nose included. Just a guess.

Wow, talk about a blast from the past. This is really offtopic from pterosaurs, but how's the forum going? Anyone remember me? Some Guy? Where's MStar?

I kinda sorta remember you, yes. I haven't seen MStar recently, or Big Al, or Spinodon, or SK, or Qwrup. I miss'em. Those were fun days.
