Apparently, larger theropods probably lacked feathers because it would have led their body to overheat (unless they lived in cold regions, like Yutyrannus). Now large dromeosaurs like Utahraptors were larger than a polar bear while living in an environment that was the exact opposite of the north pole climate wise. So isn't it possible they were featherless/sparsely feathered too?
>>5086289Because they aren't that big. Polar bear sized at max
Lions and tigers are covered in fur.
>>5086289>we"we" don't know anything because we are 50% retards, maybe more.why do you include yourself in a group that knows things you don't know?
>>5086289Moas and Elephant birds were densely feathered and they weighed roughly the same as Utahraptor.
>>5086289They weren't too big for feathers as others have pointed out, but you're not far off on us not knowing the density of feathering on at least eudromaeosaurs.No eudromaeosaur fossils have been found with feathers preserved; reconstructions are always based off of othe dromaeosaurs. This doesn't mean that they didn't have feathers, though, since they had quill knobs. It's just that we don't know the extent or type of feathering.Actual paleontologists have admitted that we don't have any evidence for udromaeosaurs having *flight* feathers like your pic depicts, for example. Smaller dromaeosaurs capable of gliding like Microraptor did.
>>5086430Hmm interesting. Yeah like the other guy pointed out, moas and elephant birds were densely feathered. Like you mentioned, the strongest evidence for feathering are quill knobs, like there are birds without quill knobs that have feathers but birds with quill knobs straight up have flight feathers.Do we know for sure that Utahraptor had quill knobs? From what I can find on the web, we only have evidence for velociraptor, microraptor and deinonychus.
>>5086839It's weird how you both fucked up the same Google search in the exact same wayMakes you look like one retard talking to himself instead of 2
>>5086289Utahraptor had quill attachment sites in its arms so we know it at least still had display feathers on its arms. But in general, Utahraptor was not big enough to be less feathered than a Moa or elephant bird. Arctotherium and Arctodus were an order of magnitude heavier than Utahraptor and they were fluffy.
>>5086839I think the general conjecture is that they couldn't fly but could have used it for gliding possibly when a baby, and for breaking falls as an adult
>>5086891the arms of Utahraptor haven't been found last I heard.Dakotaraptor is the one you guys are probably thinking of. Weird you ALL missed this. >inb5 it's in a private collection so it doesn't countbullshit. Photographs are perfectly acceptable for a holotype. So are drawings.
>>5086933also weird 2/3 of the anons that missed Dakotaraptor in their search also don't know what flight feathers are. Is this some /an/ headcannon or do we have a bot that comes on 4chan to lie about feathers? Or just one schizo talking to himself for years on end?
>>5086928arent they a terrestrial species, and not an arboreal one, what would they need any of that for
>>5086289Do not reply to featherfag threads. Do not engage with featherfag posters. They do it for attention.
>>5086933Dakota can be considered when it stops being fragmentary chimeric nonsense.
>>5086949nice AI-upscaled jpg, faggot
>>5087051>this large raptor arm with quill knobs doesn't count because it might be named wrongYou're an idiot
>>5087061Ofc the tripfaggot is an AIjeet
>>5087140Way too many indians in this board i swear
>>5086943You could say similar for some flightless birds as well. Evolution isn't perfect and more scattershot.
>>5086847>>5086935>Google searchI heard it straight from the mouth of one of the paleontologists behind the recent Nanotyrannus paper.https://youtu.be/cRUoUS2nQeA?t=672
>>5086289Weren't raptor arms supposed to aim forwards?
>>5087505No. If they're facing forward they're quite literally broken wrists.
>>5087108>implying it isn't from Anzu
for those out of the loop>Dakotaraptor is maybe (highly fucking likely) a chimera consisting of>arms and legs from Anzu a type of Oviraptorsaur>wishbone is actually a entoplastron from a turtle>and now recently the sickle pedal claw is suspiciously close to Nanotyrannus' manus claw since it's revivalleaving only a few scraps of vertebrae that belong to a Dromaeosaur lol.
>>5087526What a shitshow
>>5087455no you cant, its not the same at all
>>5087517hes asking about the arm, and why would it be folding back, that makes no sense, because we know that medium to small size theropods use their arms to grapple prey, as seen in dilophosaurus and reduction in arms as theropod size increases as seen in tyrannosaurids
>>5087061The only way to depict a dinosaur with feathers is with AI since it's such an obviously fucking retarded idea FAGGOT
>>5087519>implying Anzu's arms aren't diagnostic
>>5087527the only part he isn't lying about is the turtlethe rest is just some bullshit he made up. If it was true someone would have published it by now./an/ is where you go to listen to retarded schizos lie about dinosaurs.
>>5087561The reason nobody published anything is because the holotype is stuck in a private collection and Robert DePalma will have to stop being a faggot and let other people examine it. But other palaeontologists like David Evan's knows that Dakotaraptor is a huge chimeric mess but they can't prove it until DePalma lets it go (he won't because that would de-sensationalize his discovery).Behold actual demonstrated corruption in palaeontology.
>>5087639Photos work just fine. This is how we know you're a retard and a liar. If you can assign the arms to another species based on a photo you can publish it
>>5087692Unless you can’t come to conclusions by photo alone, which is exactly why there is two different camps regarding this matter. Those who think the bones are sufficiently different from Anzu and those who think that the bones are too heavily eroded to jump to that conclusion and that to confirm their identity they require actual in person examination. Both camps are making their arguments based on what they see in the photos, however people who believe the latter can’t prove what they think since they are being denied access to the material.
>>5087526Tyrannosaur claws are broad in cross section, the dakotaraptor claw is flat like utahraptor’s. But even if that weren’t the case there is a giant dromaeosaur in hell creek for certain. Whether the name dakotaraptor is valid or not doesn’t change that
>>5087547>um, I only used AI because...uhhh...feathers are retarded!your arguments make no sense, dipshit. Tripfags need to hang
>>5087738>Unless you can’t come to conclusions by photo alonethen you can't say the arms belong to Anzu.>Both camps are making their arguments based on what they see in the photosno. Arguments in science are published. Do you not understand this? If nobody is publishing, there is no argument.it's just you making shit up on 4chan all day.
>>5087739>Whether the name dakotaraptor is valid or not doesn’t change thatDakotaraptor being a chimera doesn't invalidate the name unless the only parts belonging to Dakotaraptor are NOT diagnostic.this is unlikely. It's possible that Dakotaraptor contains multiple dromaeosaurs, but all of them appear to be diagnostic.
>>5087773>Dakotaraptor being a chimera doesn't invalidate the nameCorrect but that doesn’t stop retards from making threads about how “dakotaraptor isn’t real”
>>5087792It seems extremely unlikely that out of our population of a few dozen posters there's more than one that holds the same wrong opinion about an esoteric topic most people have never heard of and don't care about.
Thoughts on Spike? It's an undescribed subadult caenagnathid from the Hell Creek that was recently auctioned off for over $3.7 million.
>>5087801this is why I find it very unlikely that anyone here talks to paleontologists that told them there's no good evidence of feathers in raptors, and then forgot about the quill knobs in Dakotaraptor and Dineobellatorand even weirder that anon is answered by supposedly another anon who claims to have googled the topic and ALSO missed Dakotaraptor and Dineobellatorwhat are the odds of three completely different morons all making this exact same very specific mistake, and one of them being a dinosaur paleontologist?basically just bullshit. Like every dino thread here.
>>5087803finally it's gonna get described thenbetter this than to rot in some fucking museum archive ignored by everyone
>>5087801Very possible but I’m not keeping track
>>5087804See >>5087481 or shut up you fucking schizo.
>>5087829I was talking about you, not to you
>>5086289They didn't, and featherfags will hang on the DotR
>>5086289Hollow bones mean lighter mass, plus evidence points towards countercurrent exchange so they likely could have endured much higher and lower temperatures with the same density of feathers, which would be higher than comparable mammals.
>>5087830You're not talking about me; you're making up shit I said.
>>5088267no, I'm talking about what you ignoredignorance is the act of ignoring
>>5086289we dont
>>5090175We do though?
>>5090203I don't think we KNOW they did (as in, i don't think there is direct evidence) but unlike with the whole T. rex shitshow, it's pretty fucking obvious they did
