Archovember 2024 Day 10 - Arambourgiania philadelphiae

Arambourgiania philadelphiae was a giant azhdarchid from Late Cretaceous Jordan, the largest known azhdarchid, and possibly the largest flying animal to ever exist. It was discovered before its more famous cousins Quetzalcoatlus and Hatzegopteryx, however, it is only known from a slender, 78 cm (31 in) long neck vertebrae and some other fragmentary wing bits. Based on the proportions of its cousins, this would give Arambourgiania an estimated wingspan of 10 metres (33 ft). While the size of a giraffe, air pockets and hollow bones would have made it lighter than one, at around an estimated 227 kg (500 lbs). Like Quetzalcoatlus, it was probably still capable of flight, and based on the makeup of its humerus, was likely a soarer rather than a flapper. Also like its cousins, it was most likely a land-based, stalking predator of smaller animals, and would have only used its massive wingspan to escape threats and move to new hunting grounds.

Arambourgiania’s neck bone was found by a railway worker in the early 1940s, during repairs on the Amman-Damascus railroad near Russeifa. As far as I can find, it is not attributed to a specific formation, and Maastrichtian-age fossil remains in Jordan are scarce. It was likely a hunter of small mammals, lizards, dinosaurs, and amphibians, but its unknown what larger animals Arambourgiania would have encountered. During the maastrichtian, the common dinosaurs of the time would have been ornithopods, ceratopsians, ankylosaurs, pachycephalosaurs, titanosaurs, abelisaurids, ornithomimosaurs, tyrannosauroids, therizinosauroids, dromaeosaurs, troodontids, oviraptorosaurs, alvarezsaurids, and avialans.

Archovember day 10! Arambourgiania philadelphiae! An Azhdarchid from the late Cretaceous! We actually have information on this one that comes from this year which found out that this pterosaur has a similar structure to soaring birds as opposed to continuous flappers like some other pterosaurs. Watching a 14 ft animal with a 30 ft wingspan soaring way up in the air must have been something incredible to see (although horrifying for those below if youre small and delicious to the Azhdarchids)

Another set of OCs, only this time, I've been working on them for years now!

A while back, I doodled a boy in an airman outfit palling around with an azhdarchid pterosaur and started drawing them together a whole lot. I put them in a sort of Dinotopia-esque setting wherein humans and prehistoric animals coexist.

This is one of the works I have in mind that I do genuinely want to publish someday! I'm definitely thinking of doing so with this alongside the monster school idea I'm working on.

I have a LOT of content for these two and the other people and creatures that live in their world, so there's more to come!

PS: Yes I know the shading on the third image is shit. I'm not used to shading.

Avemetatarsalia: the group that includes Pterosaurs and Dinosaurs

As per usual, you have everything you need to care for the animal and are completely prepared. The animal will not eat you and will be your companion. Yes, even the Azhdarchids. If you can ride a T. rex into traffic, you can ride a Quetzalcoatlus into the clouds.

I had to extend beyond dinosaurs for this poll because, unfortunately, most flying birds aren't quite big enough, and also, I know we all want to ride pterosaurs.

Assume all options can hold your weight because I'm not sure any could and this is just for fun

Archovember day ten! Arambourgiania Philadelphiae

wanted to try a nice background this time, this one was actually pretty quick

This one for Invozer on Art Fight of their arambourgiania lad.

[milfspiggy]

hey i dont think- i dont think thats what they look like.

[cinnasaur]

i seriously wish i could personally see a living pterosaur in person more than any other group of extinct animal, like. despite having learned so much about them and generally understanding what they would have looked like, not to mention recent media like prehistoric planet depicting them in such a lifelike way, i still think it would be hard to comprehend the sight of one in the flesh. i think an azhdarchid would be a more terrifying sight than pretty much anything i can think of

Archovember is here once again! Looooots of theropods this year. Also a lot more dinosaurs in general than other archosaurs. Sorry. There were just too many I wanted to add!

I also apologize that there are several redraws in this list… I included a couple animals I’ve drawn for past Archovembers that I wasn’t quite happy with (7 to be exact, oop). If you’ve been drawing along since the beginning and don’t feel like drawing a repeat, feel free to substitute a related species!

For new folks: this is my “Draw Dinovember” list that I expanded out to include other archosauriforms. I started doing this a few years ago to challenge myself to draw species I’ve never drawn before and/or ones that don’t get a lot of attention. Feel free to join in! You can do the whole list, just the dinosaurs (the names in green), just the pterosaurs (orange), just the pseudosuchians (blue), just the 3 oddballs (red), just your favorites, just ones you’ve never drawn before, pick one blindly, roll a D20 and a D10 and draw the sum of whichever numbers you get, etc. Just make sure they’re posted on or after their specific day! You can use #Archovember or #Archovember2024, as those are the tags I follow. Be as detailed or as sketchy as you’d like! I’ll be leaving the story highlights on my Instagram (also SaritaPaleo) from last year’s Archovember up until November 1st, if you’d like to see what people have done in the past! (This challenge usually gets a lot more traction on Instagram; so I would recommend checking it out there if you have one!)

As a disclaimer that I am obligated to give every year: when you are looking for refs for some of these species you will come across David Peters. This guy posts a lot of pseudoscientific images featuring lesser-known species, and his stuff can sometimes dominate search results. Do not trust anything from sites called “Reptile Evolution” or “The Pterosaur Heresies.” Peters’ constant outpouring of material has a habit of clogging up search results, misleading and tripping up people who may be trying to get into paleoart. He fooled me when I was first starting out! If you’re drawing along and are having trouble finding legit references, send me a message and I can send you what I’m using!

Some old art of my "dinosaur-human coexistence" concept, featuring characters OTHER than the protagonists!

These characters are Maria and her son Davey. They run an inn that Ben sometimes stays in during his travels. Maria's companion is a Tetrapodophis named Fourfeet and Davey's is a Rahonavis named Cloudy, whom he's trying to teach how to talk.

The next pair are Ren (blue hair and pronouns) and Irwin (blond hair). Ren is a person living on an island to the east of the continent working to become a veterinarian. They actually become Ben's love interest when he and Windryder crash land in front of their family's home. Their companion is a Leptoceratops. Irwin is a boy who lives on an island to the west of the continent and he and Ben get wrapped up in an adventure involving pirates. His companion is an elasmosaur named Nessarose.

These two are Alon and Typhoon. Alon is Ben's grandfather and a fisherman who trains pterosaurs to fish with him like cormorants. His main pterosaur is Typhoon, an albino pteranodontid (originally meant to just straight up be a Pteranodon, but I'm thinking of changing him to a Tethydraco) who's been with him for nearly forty years.

And this image is just a better picture of Ren, since I feel like the one with their Leptoceratops friend didn't show enough detail.

All these characters belong to me!

Following up on my recent posts about dinosaurs of the Levant, I am pleased to announce a new azhdarchid pterosaur in Jordan!

Source:

Introducing Inabtanin alarabia, a pterosaur from the Maastrichtian, in the Late Cretaceous. It had a wingspan of 16 feet (this is relatively small for an azhdarchid).

Its genus name means "grape hill dragon", from the colour of the hill where the holotype specimen was found back in 2018 (it takes scientists a while to formally describe a new find sometimes), and the species name refers to the Arabian peninsula.

I will add, in relation to my prior posts, that though found across the border in Jordan, given its size and flight capability, Inabtanin would most likely also have been native to the lands that are now Israel and Palestine.

Here are some pictures from the link:

Per one of the comments, the Pterosaur on the left is the new Inabtanin, while the one on the right is its larger relative Arambourgiania, also an azhdarchid from late Cretaceous Jordan.

Hatzegopteryx is a genus of azhdarchid pterosaur which lived throughout what is now Europe during the Maastrichtian stage of the Late Cretaceous period some 72 to 66 million years ago. The first remains of Hatzegopteryx, consisting of two fragments from the back of the skull and the damaged left humerus, were found during a student dig during the late 1970s from the upper part of the Middle Densuş Ciula Formation of Vălioara, northwestern Hațeg Basin, Transylvania, western Romania. Additionally a partial femur was found nearbye along with a mandible. It wouldn’t be until 2002 that these specimens would be formally described by French paleontologist Eric Buffetaut and Romanian paleontologists Dan Grigorescu and Zoltan Csiki, who named the animal Hatzegopteryx meaning Hateg Wing. The specific name thambema is derived from the Greek word for “terror” or “monster” in reference to its huge size. Additional specimens of Hatzegopteryx have since been recovered from other localities. Reaching around 10 to 16.5ft (3 – 5m) tall, 500 to 700lbs (227 to 318kgs) in weight, with a 33 to 39 ft (10 to 12m) wingspan, hatzegopteryx was among the biggest of the pterosaurs and one of the largest animals to ever fly. Unusually amongst azhdarchids, Hatzegopteryx had a gigantic wide skull bearing large muscular attachments, bones with a spongy internal texture instead of being hollow, and a short, robust, and heavily muscled neck measuring 1.5 metres (5 ft) long. This meant that whilst other azhdarchids such as Quetzalcoatlus and Arambourgiania where taller and larger, hatzegopteryx was stouter and more strongly built. Which meant that hatzegopteryx could tackle larger prey. In life Hatzegopteryx inhabited Hațeg Island, an island situated in the Cretaceous subtropics within the prehistoric Tethys Sea. In this island of dwarf dinosaurs hatzegopteryx would have been the largest carnivore around and occupied the niche of apex predator.
