The tooth study on Sinornithosaurus does not share any characteristics of other Sinornithosaurus specimens, so it has been sadly ruled out, very interesting concept however
I discovered your site by accident the day before yesterday while looking up some stuff about dinosaurs and have been glued to it since. Imagine my surprise and delight when I found out that you covered many other species as well. I think I have spent about 30 of the last 36 hours here! The presentations are so interesting and complete and the number of species is phenomenal. You have gotten yourself a new Patreon. Even though I can't put a large amount every month I am doing what I can and maybe - if I ever get back to work! - I'll be able to do more. Thanks again.
Spare time investigation can really be enough. If you're dedicated and really spend the time, for several years. I know, though not from paleontology. You should try. 🙂
@@Maxolotl124 Yeah the Hoatzin is a member of the Neoaves the same group of KPg survivors which diversified into nearly every living bird group including songbirds parrots, terrorbirds, falcons, penguins, swifts, hummingbirds, accipiters(hawks and eagles) and owls among many others. I think it has been argued however according to fossils and genetics that they might be the most basal or first to have diverged among the neoaves not long after the Kpg extinction so it might mean that the ancestor of all neoavian birds had functional claws. Of course the neoaves like surviving placental mammal groups underwent a rapid radiation into a wide array of body forms and shapes so it is hard to say what exactly they looked like but presumably the features possessed by those survivors descendants would have had some representative presence. What is particularly interesting to me is that the Neoaves appear to be the only group among the 3 surviving lineages of birds that underwent this kind of explosive diversification of forms and niches the other two groups the Galloanserae or fowl birds basically stuck to their same ecological niche as before the K-Pg extinction while the last group the Paleognathae with a few exceptions seems to have gone on to evolve into large flightless birds. Basically why did only one major group of birds experience this rapid radiation? was it something to do with them likely being a generalist versus a lucky specialist? Or may it have been that the Neoaves were just first to diversify outcompeting any of the other bird groups attempting to fill new niches?

Bird evolution is my favorite topic. Thanks for the video :) I especially enjoy the theory that their flight capability stemmed from “running up a tree”, for juveniles to escape to the high ground from predators. I sometimes sleep thinking about it.
@@pierre-samuelroux9364 I am sorry, my word choices were poor. What I meant was I thought the dromaeosaurid evolved from small, mainly terrestrial ancestors then evolved power flight later on and not from fight-capable ancestors then to become mainly terrestrial animals later on in their evolution.
Imagine forests full of trees full of 'rodents', mostly safe from the ground. The appearing of small gliding and flying predators must have been a big change.
I am honestly surprised that I did not stumble on your channel sooner. The information presented is amazing and even when I think that I have a somewhat good overview of a topic, I still learn so much more that just makes my jaw drop. Truly amazing videos!
TurkoosiTerapsidi I am not sure if the name comes from Sanskrit or not, but if it is, it means deep time, or great time, eternity. Edit: Just checked, it does come from Sanskrit.
possibly though remember that its body isn't really well adapted for running as the foot wings would interfere with their ability to run so I don't think this is all that likely though it can't be ruled out Also from what I have read while many species of microraptors fail to meet flight thresholds many members of the microraptor group particularly later ones seem to have developed more well defined muscles analogous to birds flight muscles with wing loading and muscle strengths well in the range to support powered flight. In fact I remember reading about comparative analysis studies and modeling suggesting powered flight evolved at least 2 or 3 separate times among the feathered dinosaurs. So it seems probable based off more recent research that flight did arise within the microraptor line but it did so *independently* of birds. There are a number of ancestral shared characteristics that probably predisposed the evolution of flight in the larger clade and incline running seems a pretty good possibility for one of these adaptations so I don't think these are mutually exclusive ideas. evolutionarily separately experiment
Oh, cool! I always wondered whether the shine or gleam or refraction of light of these guys' feathers was just made up for the artists' renditions. I love that they really were evidenceably iridescent!
I recommend looking up what velociraptors and tyrannosaurus sounded like. They didn’t actually have voice boxes so the new depictions of the noises they made are terrifying.
I would love a shirt with the new, neon red "Mothlight" logo on it, maybe a small one on the front and a big one on the back. A black or charcoal gray shirt with that on it would be sick.
The small teeth in the front of sinothosaurus' mouth may have been used for grooming similar to, ironically, mammals that have similar smaller incisors used for the same purpose. Cats or even lorises have these small teeth that comb their fur. The bigger teeth may have been equivalent to canines, again, similar to mammals that have similar arranged teeth.
The concept of raptors descending from flighted/gliding ancestors certainly makes sense; otherwise, the winglike arms are somewhat difficult to explain.
The only thing that is difficult to explain for me is choosing whether it is for gliding, warming eggs during incubation, steering while running, or the most obvious, courtship display or combination of any of the four.
Lol glad to see Ken Ham has changed his ways ;) 🙃 I do kinda miss the fantasy of humans and dinosaurs living together from the creationism books of my indoctrinated youth
May never have happened in the past, but with genetic engineering, it may yet happen in the future. Let's hope future _gene zoos_ have better safety management than Dr John Hammond though.
I thought most paleontologist nowadays don't distinguish between dinosaurs and birds anymore. Birds, and even modern ones, are dinosaurs. Aves are just the more derived form of dinosaurs.
You ought to make a distinction between people being unintelligent and people being wrong. I think Ken Ham is very intelligent. I also think he's wrong,
@@grantbartley483 weird statement - intelligent person learn and read and have at least common sense - this idiot didn't just have wrong complex scientific calculations, he read the piece of literature, about fictional events, written by people, and thinks it was real!) U don't need science to know that Hogwarts and Mordor are not real...
@@nickzaytz5712 What's hogwarts got to do with anything? If you jump to bad analogies to make bad arguments that too is unintelligent. Guess what I think of you.
The videos on this channel just keep getting better. I had a quick question though. I seem to remember reading about that some feather pigmentation studies were actually incorrect or at least inconclusive. Unfortunately can't remember the paper. Is it known for certain that microraptors feathers were in fact black?
I wonder if the leg feathers might not have been used to make up for their lack of tail feathers like in modern birds. I'd think the boney tail would have stabilized them whether gliding or flying but would have restricted agility.
The image of the Feathered winged dino eating an animal that looks like a modern canary is very striking to me, because it looks so anachronistic, even if I know it's true.
Not everybody is American. Here in the UK, where this video guy is from, we neither know nor care who this Ham person is. It appears to be religious, which again we don't really do, so neither are we freaked out by people who are into it, if you see what I mean!
Thank you for this excellent and fascinating video. I would like to share it with a friend who does not have English as her primary language, would you please provide Subtitles, if possible.
Love when different offshoots co-exist (don't know the scientific term)... like ape-men and homo sapiens... modern cats and sabre-tooth cats... birds and bird-like dinosaurs.
I love how we can reconstruct details of the life of long gone species by logical deduction. Of course, nothing is written in stone... Lol. But some things _are_ written in stone indeed.
I dislike how controversial the "Dromaeosaurs are flightless birds" hypothesis is, because even though the BAND crowd gloms onto this, it doesn't help their case and it is itself not really that big of a change from the current taxonomy.
i thought i saw something were on NOVA that microraptor held its legs vertical cuz they did a model test that it wouldnt glide well if its legs were bent horizontal.
If dromaeosaurs really were just weird birds, then the comparison between them and extant birds of prey would be even more applicable than it already is.
The possibly venom injecting teeth could have slipped out of their sockets if there was an adaptation to reduce the likelihood of damage during injection - a built in degree of flexibility and/or the venom glands - or even particularly nasty bacteria (as in the Komodo Dragon) eating away at the socket for a short period after death. Whilst the idea that it may have been venomous may indeed be wrong - just assuming it to be wrong because the teeth have slipped out after death seems a bigger sweeping assumption than considering reasons _why_ the teeth seem to have a tendancy to go adrift after death.
Thank you so much for doing this video. I enjoyed it. China has so much secrets with its diversity of strange dinosaur life unlike anywhere else in the world. China is known as a hotspot country for paleontologists, becoz so many weird and wonders have been discovered there.
I think we shouldn't make the definition of "bird" more complicated than it needs to be: Birds refers to the earliest bird (and all descendants) that had neither teeth nor a tail.
All birds have tails, they're just often shaped differently then in some of their dinosaur ancestors. There's also other complications, like how some early birds seem to have been born with teeth but lost them as they matured.
Thank you for all your hard work and excellent presentation! I've one criticism: when you describe microraptor and it's close relatives "... an evolutionary experiment ...," which I know you know isn't correct because evolution has no goals and is not directed. Obviously it's just a manner of speaking but because of the great deal of confusion re. evolution in some parts of society, it's best to avoid misleading language. Wow, I wish there were more TH-camrs about whom the worst I could say is please use more accurate language! I really enjoy your work!
no. they are not vacuum. they are all filled with air sacks and connected to respiratory system it helps them to reduce weight. it helped large theropod dinosaurs to be very big, and it helps in flight in birds.

It would be cool if you would do a video about the history of birds. I never totally understood how they evolved, what was their oldest relatives.
I don't think paleontologists do either. From what I understand there are still a bunch of missing links in the fossil record.

You should do an episode about Hoatzins, the closest bird to a dinosaur alive today
I skeptically looked that up and holy shit what an amazing animal. A bird with f-ing fingers!

I think the enlarged flight muscles would have been used for wing assisted incline running up trees instead of flapping flight
possibly though remember that its body isn't really well adapted for running as the foot wings would interfere with their ability to run so I don't think this is all that likely though it can't be ruled out

The concept of raptors descending from flighted/gliding ancestors certainly makes sense; otherwise, the winglike arms are somewhat difficult to explain.
Wings can also be used for steering while running, this is commonly seen in ostriches. It also allows them to insulate their nest more efficiently.
