One of your best works in my own opinion!!

I spent early October  talking to Palaeontologists on the Isle of Wight & they convinced me that the bigger Azhdarchidae were unsuited to an aquatic lifestyle because of there small hands & feet, plus remains of young dinosaurs have been found in their stomach cavities so they were almost certainly hunter/scavengers.

Sorry; azdarchids are more like storks than herons. Necks were too stiff to be fishing like that.

The neck of Hatzegopteryx doesn’t have to be as flexible as a Heron as its beak is much longer, we’ve been hear before on ‘Walking with Dinosaurs’ Diplodocus had such a stiff neck it couldn’t browse from trees. Sometimes experts talk absolute rubbish!

Those "experts" didn't consider cartlidge beetween the bones , if they reconstructed a rabbits neck would have been just as stiff...

Thanks for your comment H, if the long neck wasn’t for reaching up to the trees it must be for reaching down to the ground or water (its got to drink) If it could catch a fleeing hatchling or lizard it could catch a fish  :) (Smile)

True, but that dosen't change the fact that Azdarchids are considered terrestrial predators for a reason.

Experts aren’t agreed as to the diet of Hatzegopteryx but there are numerous illustrations of them feeding on hatchling Sauropods (hardly a sustainable diet as Sauropods probably had just one clutch a year at the end of the dry season) Therefore I felt it necessary to explore the other possibilities.

Kinda silly still, seeing how short and robust Hatzegopteryx's necks is.

Thank you for your comment but please see Mark P. Witton’s illustrations in his new book PTEROSAURS.

Wait, didn't it have a shorter, thick neck? I'm not hating on your drawing I just thought it did.

If the neck looks too long, I was trying to get some perspective :) (Smile)

Long neck or not, it still is great.

Thanks T, the reason I don’t give my long necked Pterodactyloids fat necks is because their centre point of lift is already way behind their centre point of gravity. They could gain stability by sweeping their wings forwards but swept forward wings aren’t efficient at low speeds and it is not in the nature of nature to be inefficient. In the flying model of Quetzalcoatlus tested by Dr Paul Macready in 1985 the wings are swept forwards & the thin neck rotates upright to solve this problem, even then I bet there were lead weights in the legs?

Thanks TB, Recent research into pterosaur aerodynamics indicate that the leading edge membrane (propatagium) may have extended further forwards as the pteroid bone was much more efficient in the forward position. When illustrating pterosaurs like this they look less front heavy :) (Smile)

Interesting! Thank you for the information.
