Many comments about the narrator's barely audible voice and the high volume of the music. Not in my device . I like this documentary a lot. Incredible giant and tiny flying reptiles that I've never heard about. Thanks for this excellent video.
The amazing creatures of distant past is a puzzle constantly being added to, the evolution of any creature is long and diverse, the future archeologists will fill in the blanks as time goes on, there's so much lost to the eons of time.
I really liked this documentary. Congratulations. It´s somehow sad that they by the end of the Cretaceous period they had grown so big no specimen survived. If they had retained small to medium proportions they could have survived like birds.
@@kimzchaos Jurassic World does an absolute travesty with their depiction of their dinosaurs and other creatures like mosasaurs. They should have used their gargantuan budgets to have more accurate and real life depictions (as discovered in modern day science)
Birds didn't survive only because they were small. There were large birds at the end of the Cretaceous but none survived. There were small toothed birds and none of those lineages survived either. Only some _toothless_ small birds survived the K-Pg boundary event from which all modern birds descended. It was probably as much luck as anything else but being small and having a beak played a large role in their survival. Beaks are more special than people realize.
Correction: Pterosaurs are lepidosaurs related to Middle Triassic Cosesaurus. That’s why pterosaurs had splayed limbs, a sternal complex, an elongate manual digit 4 (the wing finger) and an elongate pedal digit 5, as in lepidosaurs, not archosaurs or dinosaurs. The smallest pterosaurs were the size of the smallest hummingbirds, much smaller than songbirds. Able to fit inside a human hand, Cosesaurus was bipedal, which enabled flapping. That ability is also documented by a locked down elongated coracoid, as in birds. Bats have elongate clavicles also by convergence. Cosesaurus also had fibers trailing the short forelimbs and uropatagia trailing the hind limbs, as in pterosaurs. A pteroid (wrist bone) and prepubis are also present along with a long list of other pterosaur traits. Lagerpeton has none of these traits. The feet of Lagerpeton are very different from those of Triassic pterosaurs, too. Martin Ezcurza ignored the literature (Peters 2000) when promoting Lagerpeton, which nests with proterochampsids like Tropidosuchus, which have similar feet, pelves, etc. Keyword ‘Cosesaurus’ and ‘ReptileEvolution’ to learn more.
@@flap.d.jack247 Dinosaurs are reptiles. You cannot belong to a group of reptiles without being a reptile. A crocodilian and a turtle are both more related to a bird than to a lizard, so they must also not be reptiles. Pterosaurs cannot be reptiles, either, by your logic.
Birds are so thin, they appear to be weak and fragile, watch a heron eat a rat or a rabbit, their beaks are vicious spears, they are incredible hunters.
I am a college professor of Archeology and Ancient History. This documentary really got my attention. I tried to watch it, but had to stop! The background music became the dominate. Subject matter should be dominate.
I totally agree.. He whispers so softly.. It basically useless for a very large group of people... Wich is really sad..., because the content is great.. If only the narrator would speak a little louder.. Greetings bibia
To find out more about the Hatsegopteryx, search for more about the island of Hatseg, which existed where Transylvania in Rumania is today during the Cretaceous period. Similar to the Quetzalcoatolus, Hatsegopteryx had a wingspan of up to 12 meters.
A lot of people here complaining about the background music, but I don't think the music is the problem as much as it is the narrator speaking in a very low, soft voice, barely above a whisper. Otherwise, an enjoyable documentary.
Today there are thousands of bird species alive. At any time during the Mesozoic Era there may have been thousands of pterosaur species alive. Paleontologists haven't even scratched the surface of pterosaur diversity.
I have literally spotted this bird in Vrindavan, Uttar Pradesh, in India, while I was relaxing on my terrace, it went straight above my head with so great pace that I couldn't capture it and the building also obstructed my view later, I am pretty sure that bird was a pterosaur with long beaks and enormous wings in a pink shade, that was the most I could observe at that small moment of time, the place where I was living was near a dense forest and i believe that forest still holds dinosaur species which are regarded by scientists as extinct!
Hmm, who knows? Most of the ecological niches, which the pterosaurs filled, seem to have enabled or required them to fly… or, so it appears… not sure why they’d want to forfeit that adaptation. But nature can be a b*tch sometimes! Lol! Also, allegedly, all extant (plus extinct) species of ratites are thought to have descended from ancient, flying species. Same with penguins & their ancient descendants, which were thought to’ve had flight & migrated to Antarctica, where the only predators would’ve been cetaceans & pinnipeds, so they lost their ability to fly. Not sure of the ratites’ (or penguins’) exact points of origin, but ancient ratites supposedly flew to places like New Guinea, Australia & New Zealand (for emus, cassowaries, kiwis + moas), Madagascar (the elephant birds), Africa (plus the Middle East & India for ostriches) and South America (rheas & tinamous). Then, once there, nature apparently decided “you don’t need wings to fly!” Even with predators… so they “devolved” that trait. interestingly though, some of the tiniest pterosaurs, like _Anurognathus_ or _ Nemicolopterus_ apparently had the lessened flight capability. They were so tiny, they likely didn’t truly FLY-as in, flapping their wings, riding thermal drafts for long distances, etc.-but lived quite similarly to modern, arboreal flying squirrels or flying lizards. In the forests, they could flee from predators or just move from tree-to-tree via “falling” or “jumping” with ”grace”, using their wings…
Sorry I went on a thought tangent there, lol. There are two informative videos about this topic, on PBS Eons, if you’ve seen them… the one on ratites is here - ruclips.net/video/M3h05ajJw0o/видео.htmlsi=UHbDKbRJ8T9RnrRy …and the penguins one is ruclips.net/video/HMArjGQwLvY/видео.htmlsi=uT7GQejcTQfLpl0X
There is an audio problem in this video. To start with, the narrator's voice is not very crisp. Additionally, the music plays at the same level as his voice while he is speaking. As a result, his words tend to get drowned out by the music. If the music were left in the background it would be so much better. It is very annoying and unnecessary. Otherwise this could have been a good video.
Great documentary! Would be good to have the names you say writen down so we could easily search them. I've been trying to find the one at 31:11 but can't understand
If you enable closed captions in settings for this video, many names will appear close enough in spelling that you make get a hit if you search for the term. In this case that wasn't enough because it's such a bizarre name, so I did an image search for 'upturned beak pterosaur' and finally found a relevant picture... _Dsungaripterus_
I was looking forward to this but the background noise of that bloody glockenspiel drove me to distraction!! I couldn’t watch it. Can you please lower your background volumes.
Very interesting program. Excellent overview over the subject matter. I wonder however, if the evolution of the avian dinosaurs could have happened without the extinction of the pterosaurs? It seems they were very well adapted to their respective nieches in the ecosystem. Most of them are now filled with birds. So, I really doubt that the birds would have been able to compete for the same nieches with well adapted pterosaurs. I guess it is the same story here as with the radiation of mammals into the ecological nieches vacated by the extinct dinosaurs. Considering mammals and their suppression by the dinosaurs, the avian dinosaurs might also have been waiting for their chance to radiate? But I have not heard that there is any evidence of that available. Am I wrong? Anyway, well done. Thank you.
I think it is generally accepted that birds took over ecological niches vacated by the pterosaurs. Truth is, birds were already radiating into various niches well before the end of the Cretaceous. I recall reading that pterosaurs were declining as a group for millions of years. According to this hypothesis, birds were out-competing pterosaurs causing a gradual decline in the number of pterosaur species. The sole exception are the specific niches occupied by the giant azhdarchids. They had no competition because avian biology does not allow for body sizes attained by the largest pterosaurs, so they couldn't compete with the likes of Quetzalcoatlus and its kin. This could explain why the giant azhdarchids remained extant until the K-Pg boundary event, whereas others families were already going extinct. However, this documentary does not mention anything about a decline in pterosaur diversity towards the end of the Mesozoic. My information could therefore be out of date if recent discoveries prove that pterosaur diversity remained intact throughout the Cretaceous.
@@jamesaron1967 yes, the decline of the pterosaurs also has me baffled for some time, because I saw a paper analysing the energy efficiency of the additional wings on the Ptersaur legs. According to that paper Pterosaus ought to have been more energy efficient than birds. But I think that many of the pterosaurs species were extreme niche specialists. Niche specialist usually don't cope well with radical changes, who might have foind it hard not cope with the changed ecology of the immediate post impact world. The birds are raptor-decendents and those were a lot more opportunistic and less specialised in their survival tactics. So the birds came through. Imho.
@@helmutzollner5496 The reason birds survived and the dinosaurs, marine reptiles and pterosaurs didn't is better understood now and I agree with the theories. What interests me more is what caused the decline in pterosaur numbers in the latter part of the Cretaceous _before_ the impact. What you say is true in terms of body plans between avians and pterosaurs. Pterosaurs were supremely adapted to flight. Birds, at least during the Mesozoic, were not superior to pterosaurs in that respect. That leaves only one thing that I can think of that would make birds out-compete pterosaus in the long run, and even many mammals groups for that matter - the incredible dedication to raising their young.
@@jamesaron1967 interesting conclusion. You think pterosaurs were less caring parents. You have any evidence for that, or you assume it, because it is they the only thing left?
@@helmutzollner5496 There is indirect evidence, but it is circumstantial at best. We do not know and probably never will. The main reason I think this is based on my observations of birds over the years. Birds are my favorite animals and consequently have learned a lot about them in my lifetime. It is difficult to imagine better parents. Bird parents go to great lengths to take care of their young. The nests some species create are absolutely phenomenal, and was probably the case for many terrestrial dinosaurs during the Mesozoic. When birds hatch, they are completely helpless unlike reptiles. They absolutely need their parents without which they simply couldn't survive. Most birds develop very quickly and are at or near adult size as fledglings. They need to be so that their flight muscles are developed enough to fly, because once they're out of the nest they are very vulnerable if they can't fly well. This is a generalization of course, it's not true for every species and there are at least 10,000. Pterosaurs seem to have followed growth patterns of other reptile families. Immature pterosaur fossils are identical to adults but smaller. Evidence suggests they hatched fully formed. The main difference between birds and pterosaurs is the wings of birds are an integument structure, feathers, which require a lot of time to grow due to energy/nutritional requirements and complexity. Pterosaurs have a pantagium made of skin. It's there from day one. They wouldn't have required the level of care that birds do. Some paleontologists have even suggested that the smaller species of pterosaurs may have been flight-capable soon after hatching, and if true have hardly required much parenting at all if they could seek food on their own. I admit this is highly speculative and generalizing for pterosaurs as a group. Assuming it is true and pterosaurs were not as good parents as birds due to lack of need, this may have contributed to their decline in the long run when a group of competing flying animals emerged that had superb parenting skills, enabling better survival rates of their offspring. That advantage would have probably played out very gradually and that's exactly what the fossil record seems to indicate.
Had to cut this short due to the idiotic background “music”, for lack of a better term. Very disappointing as I was hoping to learn something here. Kill the background noise!!

Horrible audio, couldnt finish. Might have been good if the music didn't make it too irritating to listen to.
I highly doubt one of those oversized dino birds would entertain including human flesh to their diets if they ever did see one of us.
Not a dino or a bird.
This is the most ignorant comment I've ever seen
*they were FLYING REPTILES--- not dinos*
Doesn’t need the silly music .
The largest bird to take flight
Not a bird
@Rook I think so I think birds came from them
@@jodysams7915then uk nothing
This is the amazing story ,there are by God created all things.
Religious tripe.
I find it difficult to believe in a god that would intentionally create my disability.
*And WHO created god?*
Why are those bird dinosaurs still around? Go to old civil war videos the bird was shot down by military.
That was a movie "still."
@@anthonymorris615I do not think they had movies at that time???????
@@larrygribaudo1092 😆 sorry actually a TV show called Freakylinks (I think that was it). The photo was a prop for the show. There were actually 2 photos.
The Skeptoid Podcast did an episode about it.
@@anthonymorris615 Look at video: Living Dinosaurs in the Congo: Mokele Mbembe Part 2
@@anthonymorris615 Also look up Marco Polo, I believe he had Dinosaurs pulling his carts.
History 😅😂🤣 still have to prove fake-a-saurses first
We have an overwhelming amount of proof. Meanwhile, where's your proof of God?

Chool magnífico
Good documentary but as long as I missed it, it seems you forgot to mention one very important controversial topic, and that is their wings' shape, where they connected to their legs or hips?
wTF is a meter, your American BE American.
Damn straight
Big talk for someone who can't speak their own language properly
