Do you believe its neck was short ? I know a short necked species discovered in hatzeg.
But this guy was more related to Quetzalqoatlus

well it was the top carnivore of hatzeg and having a shorter, more powerful neck would help with prey

Ìndeed ! But it was also close relatives with Queztzacoatlus pterosaur...
👍: 0 ⏩: 1
yes but do you expect it looks just quetz when it lives in a different place and hatzeg was really weird
👍: 0 ⏩: 1
Yep ! Both of them are predatorial pterosaurs; and extremely close relatives.
Some paleontologists won't even separate them

there are numerous osteology differences that makes hatzegopteryx a distinct species compared to quetzalcoatlus
👍: 0 ⏩: 1
It's very true !
But I many I think a long necked Hatzeg is more possible because the hatzegopteryx is very closely related species (a cousin species) compared to Quetzal.

sorry, but no, cervical vertebrata of hatzegopteryx are known, and it is directly telling that hatzegopteryx had a short, robust neck
Pterosaur overlords of Transylvania: short-necked giant azhdarchids in Late Cretaceous Romania Mark Witton1, Matyas Vremir2, Gareth Dyke3, Darren Naish3, Stephen Brusatte4 & Mark Norell5 1 - University of Portsmouth, Portsmouth, UK. 2 - Transylvanian Museum Society, Cluj-Napoca, Romania. 3 - University of Southampton, Southampton, UK. 4 - University of Edinburgh, Edinburgh, UK. 5 - American Museum of Natural History, New York, USA. Azhdarchid pterosaurs are well known for their frequent attainment of gigantic wingspans (sometimes over 10m), but are also characterised by a distinctive anatomical bauplan which is thought to be fairly uniform across the group. This comprises elongate 45 jaws, long limbs and short wing fingers, as well as hypertrophied cervical vertebrae, which are perhaps their most defining features. We present evidence of unprecedented morphological diversity in giant azhdarchids with EME 315, a large and robust seventh cervical vertebra from the Maastrichtian Sebeş Formation of Transylvania. The specimen corresponds in size, histology and proportions with the 10 m wingspan Transylvanian azhdarchid, Hatzegopteryx thambema, and likely represents a member of this genus or an extremely close relative. Despite its size, EME 315 is proportionally short and likely represents a cervical III-VII length of only 1.39 m. This is comparable to the neck lengths of much smaller azhdarchids and considerably shorter than our estimated cervical III-VII length for Arambourgiania philadelphiae (2.3m), another giant azhdarchid known from cervical remains. We therefore propose that long necks are not common to all azhdarchids. The robust and short-necked azhdarchid bauplan may reflect adaptation to predating relatively large animals, assuming that, as suggested for other azhdarchids, these Transylvanian pterosaurs foraged terrestrially. Because Transylvanian azhdarchids dwarf contemporary terrestrial predators by some margin, it is possible that they were apex predators in Maastrichtian Transylvania. This suggestion conflicts somewhat with hypotheses that Late Cretaceous pterosaurs were ecologically constrained and declining into extinction during the Maastrichtian.
hatzygopteryx and quetzalcoatlus were just two different animals that adaptations suggest that they lived a different lifestyle. hatzygopteryx skull was over twice as wide as quetzalcoatlus with a more robust humerous and a proportionally shorter neck. it can suggest that it was an animal that comparatively hunted larger game then what quetzalcoatlus is use too( though that is a bit speculative) and the correlation between Romanian and short necked azhdarchids, long with dinosaur dwarfism. odds are, it's more likely for hatzegopteryx to be more related to the azhdarchids it coexisted with then the one that lived millions of years after. this would include the two other species of proportionally shorter necked azhdarchids that lived alongside hatzegopteryx
the only affinity hatzegopteryx has with quetzalcoatlus is that it was compatible in size and it was an azhdarchid. long necked or short necked, it's still an azhdarchid.

Well as far as I can tell; this is the 'current' desptriction\reconstruction of the animal

So I can say; the short necked theory is either unaccepted widely; or deemed inaccurate.
However; the fossil record of the Hatzegoptopteryx was quite new for such an extreme adaptation; the animals oldest records were 70 my. to 65 my. I don't know if the animal could shrink its entire neck structure; and re-make its whole body structure only in 4 million years; four million years is a short time to be an entire anatomy to re-evolve; I definetly would believe if that happen in 10 or 20 million years; and to be honest it's not even; entirely; clear that hatzegopteryx was a separate azhdarchid or another species\subspecies of Quetzalqoatlus. However I searched it and you're right about a short necked azdarchid do lived;
hyrotrioskjan.deviantart.com/a…
But its a seperate species and is very very small by the giant azhdarchid standars; and probably is a more far relative to hatzegopteryx. The giant Quetzl. is the closest relative known by so far. However I also search the title you give and the only animal the web show; is that particular medium sized 'dwarf' azhdarchid; who doesn't even have a 'name'.
So; either this azhdarchid evolved just recently before the KT happened; or it lived more before the Hatzegopteryx; the hatzegopteryx anatomy - so far - is quite similar to the Quetzalcoatlus; so I have no idea how shot necked nameless species would be more close relative to hatzeg.; but if you mean by evolutionary path. I honestly not sure; I guess we have to wait for more fossils...

let me start off by saying that all the illustrations you posted are very old. and secondly, every single one of those illustrations excluding the museum sculpture( which is still a rather old reconstruction) are made by Mark Witton. the very same man and artist who actually worked on the undesribed vertebra and is now advocating the evidence of short necked hatzegopteryx
as stated before the cervical vertebra for hatzegopteryx are known. it is without doubt short necked at this moment

hatzegopteryx is just too different to have any real affinity to quetzalcoatlus. making it a chronospeceise is nothing more then a baseless guess, over complicating what can be visibly be seen and proven right now.
and of course the short neck pterosaur is a separate species. those traits you listed is what makes it unique to it as a species. whats the difference with hatzegopteryx? serveral quite hard defining differences between hatzegopteryx and quetzalcoatlus that makes it distinct, and it's not just the neck
a quote from Buffetaut el at 2002
How large the skull was by comparison with other pterosaurs is known
by the width of the quadrate articulation for the mandible, which is 100 mm
in Hatzygopteryx versus 25 mm in Quetzalcoatlus sp. (Kellen and Langston 1996)
, 20 mm in Pteranodon Longiceps (Eaton 1910), and 10 mm in Nyctosaurus( von Huene
1914). The width of the skull at the level of jaw articulation, estimated from the available
specimen which corresponds to the right half of the palate, was about 500 mm
hatzegopteryx skull was over twice as wide compared to quetzalcoatlus. it's humerus is also slightly larger and of course, the cervical are significantly shorter. just like the short neck pterosaur, there are so many things about hatzegopteryx that makes it distinct and virtually nothing that suggest it being a chronospecies of quetzalcoatlus.

Oh a link ! Thank you !!
I mean it ! I honestly searched net and can't find any link belong the shot necked hatzegopteryx; I really do understand now. Thank you.
So the hatzegopteryx spent more time in land rather than air ? (
It was an apex predator of course; but may I ask does it really can fly with that anatomy ?
👍: 0 ⏩: 1
it can most definitely fly as with any large azhdarchid. the bigger the humerus just means more support for a humongous tendon for catapulting in the air. it's precise lifestyle is ,of course, unknown, but it's no reason to believe it spent the majority of it's time on the ground

Oh; okay. It's quite nice to know it was both apex at land and sky.

well quetz is considered to be more of a scavenger not needing a thick neck to hunt larger prey
👍: 0 ⏩: 1
Actually it is widely considered Quetzal too hunted smaller animals into a degree.
The animal surely land on an island with dwarf dinosaurs.
Also the Hatzeg. surely go to mainland which it primary being a scavenger at there with a lot of Predators
👍: 0 ⏩: 1
well quetz did not hunt dwarf dinosaurs
👍: 0 ⏩: 1
I am not sure... If queztzal. lands into an island; however by purpose or not; it becomes the biggest thing on the island. It can capable of hunting the dwarf dinosaurs.
However; nice artwork

Thanks and I was kinda following the short neck trend coz I wanted to make it a bit different from quetz

You're welcome ! I agree its very interesting
