You know what I'd love to learn about -- not the appearance of feathers on dinosaurs, but BEAKS. Feathers on dinosaurs seem reasonable to me. They're just the warm outer covering on something, and they don't require a radical reshaping of the animal. They're sort of a "coat of paint" on the existing animal, like fur. But bills and beaks? To me, that's the single biggest difference between the extinct dinosaurs and the ones we have around today, the birds. Beaks require a radical reshaping of the skull and the animal's most important interface with the outside world: its mouth. I mean, beaks versus teeth involves a completely different change in what an animal eats, which has got to impact its survival and living habits way more than feathers. Maybe beaked dinosaurs survived because beaks are an adaptation for animals that eat small seeds and small prey, and maybe creatures that lived on tiny living things were better able to survive post-asteroid-impact than the big toothy ones that needed to eat big old prey. I think sometimes we focus too much on the feathers as the biggest difference between dinosaurs and birds, but to me, the beaks and bills are a far greater mystery, and I just can't see how they arose. What kind of mutation would result in a beak versus a mouth? Where do the teeth go? Are there reptiles or birds that have both beaks AND teeth? Once beaks evolved, have they ever disappeared? Has such a massive alteration in an animal's mouth ever happened in other types of animals, like mammals or insects?

Good question. Actually, many species of ducks have serrated bills and those serrations act (and look) much like teeth. Also, the evolution of the beak would've taken many thousands, maybe even millions, of years. Something like that doesn't just happen over a few hundred years. As far as we know, birds haven't devolved beaks ever in the history of birds. They're incredibly versatile tools just like different kinds of teeth are for mammals and reptiles. That's not to say that it couldn't happen because of course it could. It's all stored in the genes of birds. That's why some scientists hope to genetically reverse engineer chickens to bring out dinosaur traits.
@binky28196 жыл бұрын
I think you kind of answered your own question. Beaks (most likely) evolved to take advantage of other food resources (seeds, insects) to avoid competition with other species. It's easy to see how small theropods would evolve beaks, because small creatures could survive on a diet of seeds and stuff, but even large theropods (such as Gigantoraptor) had beaks so it could be possible that they evolved multiple times. Modern day birds still have genes in their DNA necessary to make teeth, they're just not activated at any point during their development. As far as I know it's impossible for an animal to simultaneously have teeth and a beak. All insects have external mouthparts (they don't have jaws like us). And extremely modified mouths have appeared in other tetrapods, which when you think about it, it's also hard to imagine how they became so precise and specialized. For instance, chameleons have elongated tongues that they can shoot out of their mouth to catch insects from a distance, anteaters have lost all of their teeth and have a ridiculously long and narrow "snout" with an even longer tongue, some whales have also lost their teeth and replaced them with baleen which they use to filter food from large gulps of water, snakes have hollow fangs through which they inject venom to stun or kill prey and they are folded back when not in use, etc.

Similarly the presence of fuzz in Kulindadromeus, Tianyulong and Psittacosaurus would indicate (via phylogenetic bracketing) that hadrosaurs were feathery. Only we have numerous skin impressions, including the famous "mummies", of duckbills which demonstrate the presence of scales over the vast majority of their body. Clearly there was a great deal of variability in feather vs scale covering, even within closely related lineages = Parts of the tail that are clearly covered in fluff in Sinosauropteryx were scaly in the related Juravenator.

Sauropods arnt rendered feathery, although they are Saurischians and would be more likely to have them than Ornithiscians, especially derived ones like Triceratops.

Rex might have been a trait like brown hair or black hair, a lot of Theropods had feathers, but there are some Theropods like Carnotaurus had evidence that they had completely no feathers. It was also determined that Sauropods had no feathers at all. These discoveries are leading to debates if they should change the arrangement of sauropods from the dinosaur family tree. In Paleontology they are making new discoveries which will probably be a lot of changes as well. The T.rex did had evidence though that it only often had protofeathers from the back of its head to the beginning of the tail, but then they find some T.rexs that had no evidence of feathers, this is why it was determined that feathers might have been a trait like brown and black hair.

It's SO funny seeing things like this now. Back when I was a kid, watching NOVA on Public Television, paleontologists got into HUGE fights over this, with most of them ADAMANTLY asserting that birds were DEFINITELY NOT directly descended from dinosaurs, dinosaurs were DEFINITELY NOT warm blooded, they they DEFINITELY DID NOT have feathers. Poor Robert Bakker was almost the line contrarian voice back then. And I sincerely wish that these "mini sci shows" would give him more credit than they do for standing up to what was then the mainstream, majority opinion. He really put up with a lot of flack. I've always admired him for that.

We think that dinosaurs had a variety of growls, hisses and maybe squeaks, like modern birds. They probably didn't chirp though because their vocal organs aren't identical

From phylogenetic bracketing we do know that tiranosauridae had the possibility to have feathers, because Yutyranus did have, so T. rex probably had, but not like any image shown on the video, the animal were likely almost naked or even all naked in adulthood

Good documentary, but one thing is missing... dinosaurs did not all live in arid regions, a lot lived in semi-arid or even humid environments. Downs are in fact a pretty good isolation, especially for smaller animals like younglings, but this diminishes, when the downs get wet. So, a stronger and even denser type of feather could have been developed as a cover feather against that moisture and they provided best protection by overlapping, similar to shingles. And maybe this feature of overlapping, asymmetric cover feathers later on enabled flight..

Now I won't mention that recent study that pointed towards T Rex not being feathered, as even if accurate it doesn't dissuade from the larger argument made here. What I will mention is that I am disappointed they didn't go further back and mention how there is evidence of feathers in Avemetatarsalia, the clade that contains Dinosaurs and Pterosaurs, as a whole as Pterosaurs have been sound to be covered in hair-like filaments which are often linked to feathers. I have even read that feathers, or at least the base elements of them, may be basal to all Archosaurs...which is quite the thought

Thank you guys for adding verbal caveats into your information. Saying things like "may have" or "probably" give people a better idea of how solid the consensus is on many of these things. I have seen many "sciencey" broadcast programs that never make that distinction. They just throw out wild speculation, solid science, and various theories onto the screen without regard for accuracy. As long as it sounds interesting and fills time. Shows like "Walking with Dinosaurs" is a good example, and also many astronomy shows. They contain about enough educational value to maybe get a random channel surfer interested but that's about it.
