I remember watching that with my 22 year old daughter when she was very young, probably 3 or 4 years old then. Brought back fond memories of a time and place long gone.
Ah, I see an error: The video says that Rhamphorhynchus is diurnal and Scaphognathus is nocturnal. It's actually the other way around. EDIT: Another error - paleontologists are now pretty certain that ALL pterosaurs, including Pteranodon, could fly under their own power and that Pteranodon's crest was actually a mating display rather than a flight rudder (indeed, wind tunnel tests suggest that the crest would have _hindered_ Pteranodon's flight more than it helped).
Both dinosaurs and pterosaurs desended from a common ancestor. The pterosaurs decided to fly earlier and thrive earlier. The dinosaurs were smart, and invested for some time, until the pterosaurs were extinct. They the dinosaurs flew and fly as birds (which are still around) and therefore it shows that investment, in time, pays off. Why did I waste my time telling you this? Heck if I know. But it felt like a story worth sharing for some reason.
"Both dinosaurs and pterosaurs desended from a common ancestor." - unremarkable; ANY 2 taxa did "The pterosaurs decided to fly earlier and thrive earlier" - not thrive; dinosaurs predate them by a few million years "Why did I waste my time telling you this?" - quite, it's nonsense
I think it's a reasonable as well as an interesting suggestion that at least some of the larger Azhdarchidae could have been (secondary) flightless. I can easily imagine creatures like Quetzalcoatlus, Hatzegopteryx and Arambourgiania, who were giraffe sized, no longer using their wings for flight. I think their weight estimates tend to be on the low side, with some even giving a 10 meter animal an estimated weight of 70 kg, which is utterly ridiculous imo. Others go up to 200-250 kg, but I don't think an estimate of up to 450-500 kg would be outlandish, seeing as how enormous these creatures were. And those estimates are usually low because 'the Pterosaur people' really *want* Quetzalcoatlus to fly, which means they have to bring down its mass, which is why you get these (extremely) low numbers, but I think they're quite unrealistic. Many bird species have become flightless, and the largest known birds are in fact flightless birds. In fact, if you look at weight in emus, cassowaries and ostriches, then there's a huge gap untill you reach the heaviest flying birds. So it seems as if flying birds have a limit to how heavy they can get before flying starts to become an issue. The largest flying birds have trouble getting off the ground, but they're still nowhere near the weight of the three largest flightless birds. I think that when you reach Pteranodon size, you could be approaching the maximum weight for flying Pterosaurs, and anything heavier than that could potentially be flightless. These creatures were certainly large enough to chase away some of the larger theropods of their day, so maybe they stole other predators' kills, or could have actively hunted smaller animals themselves. Seems plausible imo.
I have to concede. Defense could be problematic, especially in North American species, which lived during the time of large Tyrannosaurids, which were probably, relatively fast animals (especially younger individuals, or smaller species), but then again, these Pterosaurs were extremely large as well, and one can imagine them using those massive beaks to inflict some potentially serious injury on other predators. But then there's the case of Hatzegopteryx thambema, which was found in what is now Europe. Wikipedia: "It is significantly larger than any other terrestrial predator from Maastrichtian Europe; due to its large size in an environment otherwise dominated by island dwarf dinosaurs, with no large hypercarnivorous theropods in the region, it has been suggested that Hatzegopteryx played the role of an apex predator in the Haţeg Island ecosystem." But then again, Europe at that time was an archipelago, so being able to fly from one island to the next would be beneficial, and perhaps necessary. So my theory may be easily refuted, and yet, I still think there might be some truth to it. And although Hatzegopteryx lived in another part of the world, when compared to Tyrannosaurus, for example, it would've still towered over it, significantly. Often reconstructed in paleoart with a long, slender neck, in reality; its neck would've been extremely muscled and robust. Rising up, spreading its long arms would give the impression of quite a formidable opponent, even to a Tyrannosaurus. For Quetzalcoatlus, I tend to agree with Donald Henderson's weight estimates, who put the animal at around 500 kg, although I'm not sure if Henderson still believes that. Based on those estimates, he suggested that they might have been flightless. Others still agree with this interpretation, and they still criticize the other estimates, which hover around 100 kg, which I think is just inconceivable. Most put it around 250 nowadays, although that's perhaps still on the low end. Also note that in Azhdarchidae, the wing finger is the smallest by pterosaurian standards, while its overall body mass was significantly greater. I honestly don't know, I just think the idea of these animals being flightless should be considered.
Just a thought from a layman, but could it be that the big azdarchids were in the 'process' of becoming flightless, with the ability to fly being relictual, in a sense? Could they have been predominantly terrestrial but retained the ability to use their wings to assist in short periods of flight to escape a predator or help to them to run down prey? What if they could fly well as juveniles, but as adult birds were primarily terrestrial? There has to be at least one transitionary species that straddles the line between flight and flightless in every flying lineage, could Quetzalcoatlus have been in that transitionary phase?
Am uncertain how anyone felt it possible to intuit what one of these animals would have sounded like. If there really is a scientific basis to it, I'd be fascinated to hear about it.

Same, everybody talk about dinosaurs, but pterosaurs are more enigmatics for science ! I imagine a throaty sound..
proposed audio sounds like the LIMPKIN, go find it!! Cornell Ornithology Lab (Merlin whole app if you like) Merlin is one source. Such speculation for the sounds of any specimen is only an indication of unknown behavior and phenologic traits. zPLEASE, do not come here to Florida to camo in an unregulated fashion. Consult our state or county before any such venture- AND ALWAYS LEAVE NO TRACE, TAKE NOTHING BUT PHOTOS AND MEMORIES.
About as unlikely for a paedomorphic form of a tunicate to evolve to develop a mineralised internal skeleton, a centralised complex nervous system and become the largest, most behaviorally complex and most intelligent species ever to have existed...
there's another flying giant that has been spotted. this creature is known as a Thunderbird, a avian colossus spoke in Native American mythology and according to the mythos of the Anasazi a similar beast known as the Wakumi is in some way related to the Thunderbird. but i think that they are in some way Pterosaurs.
fascinating that there were animals the size of giraffes that were flying
Well they didn't weigh as much as a giraffe. They onlyh weighed 500 pounds so I wouldn't say flying giraffe.
@@sebs4622 He did say "size", not "weight".
Theres a (misarable) theory that they were in fact flightless, especially as they weren't coastal like almost all the others....
@@jamesblonde2271 I don’t think it’s such an unreasonable theory!

Nilax Shirke hi
No, Giraffes are mammals! That is a giant flying pterosaur that acted like a stork.
I am glad about new episode . This series is great.
I'm a simple man. I see pterosaurs, I click.

Umm yeah but bird has been around since the jurassic and complete with pterosaurs, Which make pterosaurs larger to not get outcompeted with bird.

Well the pterosaurs did have actual hands on their wings, so they could probably support a higher body weight than birds during take-off
They've since both mathematically and Mechanically proven that Quetzalcoatl could achieve flight from a standing jump using it's arms to push off.
I like the videos with you
Is tupandactylus more relative to tupuxuara or tapejara???
Tupandactylus is closer to Tapejara, Already the Tupuxuara is closer to thalassodromeus
Let's be honest.
The reason why Pterodactyl is famous is because people think that Pterodactyl and Pteranodon are synonyms
i wonder the woman voice is from england or maybe hogwarts

Well, not synonyms, but quite closely related; pterodactyls and pteranodons ARE pterosaurs!

If pterosaurs survived till modern times they would most likely loose its back legs and walk on its wings.
Ghazt master that's unlikely to happen
About as unlikely for a paedomorphic form of a tunicate to evolve to develop a mineralised internal skeleton, a centralised complex nervous system and become the largest, most behaviorally complex and most intelligent species ever to have existed...
@@randomuser681 Anything can happen. Remember, we had animals similar to chervotains evolve into the whales we know today.
Sir, I saw on Jurrasic Park movie have two different ptera... On JP 3 and JW 1... Both of have a different beak... Can you explain?
Jurassic park and Jurassic world are fictional movies
Why can't you hear a pterosaur use the bathroom? Because the "P" is silent 😋
Oh is that dinosaur or silesaurus or suchus no that is pterosaurus
Okay it would be quite nice to not have the annoying crappy noisy sound effects, just use the voice and the backround man
In some videos it's so bad it's unwatchable

Hahaha I'm sorry!
A little lizard evolving into bird-like animals!
no
0:33 Ej to mój kolega Franek
Did pterosaurs evolved from dinosaurs?
Not really, they have an old common ancestor but they're juste close "cousins". All pterosaurs died out and a little branch of dinosaurs became birds.
there's another flying giant that has been spotted. this creature is known as a Thunderbird, a avian colossus spoke in Native American mythology and according to the mythos of the Anasazi a similar beast known as the Wakumi is in some way related to the Thunderbird. but i think that they are in some way Pterosaurs.
