I think it’s perfectly reasonable to reconstruct Nanuqsaurus fully feathered, it’s about the same size as Yutyrannus, which we know was fully feathered & notably lived in a less colder environment than Nanuqsaurus.
Yutyrannus was significantly smaller than the original reconstruction of Nanuqsaurus, and the difference has only widened as the size estimates for Nanuqsaurus have been revised upwards. Yutyrannus is also much less closely related to the giant North American tyrannosaurids than Nanuqsaurus, and all of the other animals in that crown lineage have only ever preserved scaly skin. I wouldn't be shocked if Nanqusaurus had a feathery integument, but I also wouldn't be terribly surprised if it didn't. A lot of this animal is still unknown to science, and a lot of often wild speculation has filled in these gaps.
@@CCNorsebecause we know Trex might not have feathers or might have some feathers but not much doesn’t mean Nanuqsaurus didn’t have feathers at all we haven’t found skin or feather impressions of Nanuq so we don’t 100 percent know if Nanuq was feathered or not but we know it lived in a cold and snowy environment so unless proven wrong most people think Nanuq had feathers
If it was feathered, I can easily picture feathers moulting out in thick clumps in spring, making a big downy mess everywhere. Basically like modern mammals shedding their winter coats. And I can also imagine that the spring/summer coat and winter coat of feathers would differ in coloration.
The chicks would probably be a brownish colour until they got old enough, like arctic foxes. They were probably insanely fluffy like most chicks in general, although the high mortality rate may say otherwise

Wouldn't the Cretaceous arctic temperature be ~60°f (~15°c), and without snow? That's what many sources available online seem to say for this time period
That's an average estimate. Short timescale weather is really hard to determine, so I wouldn't be surprised if it occasionally snowed during the arctic winter nights.
You're looking at the estimated Arctic Ocean temperatures, which would fluctuate a lot less than land temperatures and remain a lot warmer in the winter. The Prince Creek formation seemed to have had a mean annual temperature of 5-13°c from what I can find, depending on the source. With mean winter temperatures being around 2-4°c.
Average temperatures aren’t a good indication of range sometimes though. The climate shifted a lot over a huge time frame and at the very least places inland or at higher elevation would have experienced true winters at least some times. The same was true for the southern landmasses which would have been persistently cool-cold and sometimes extremely cold. Both the extant hot sclerophyllous and wet temperate southern biomes are descended of it. That much is undisputed. That it would be the same in the north doesn’t seem too far fetched even if not as extensive. I don’t know whether the plant fossil record in the north suggests the same but it would be a better indication. They tell us a lot more than the animal record but are often overlooked.
This is why I want to see more videos on dinosaur age polar animals. We hear all about the warm weather regions but freezing temperature regions seem more interesting to me because they are more niche and extreme
10:10 I have a different spin. The young left the nursery as soon as they could and moved northward to avoid their elders until they had enough mass to compete with them. Larger prey and milder weather to the south; smaller prey and rougher conditions to the north.
It's not a very good theory. Being that small would have been easy to hide or outrun adults. Kinda like how Komodo dragons do it despite being on a small island.
You finally gave nanuqsaurus a time to truly shine. Especially with the title and thumbnail many people will see this. You have been to make videos of obscure extinct fauna and their enviornments such as prehistoric australia viral. Many people saw those vids doing those exrinct animals justice as it brought them more fame. I hope you will talk about other animals from prince creek like dromaeosaurus and especially pachyrinosaurus :).
Nanuqsaurus is one of my favorite Tyrannosaurus beside T.Rex. I would love to see Jurassic World Rebirth use Nanuqsaurus in a blizzard like setting where you can’t see it, but it sees you. That would be a awesome scene.
Yeah, but from what the synopsis of the movie, most of the dinosaurs have died off and moved to warmer climate even though some of the dinosaurs could survive colder climate, but the writers or such don't know much of dinosaurs and this dinosaur would go against that, but love to see it tbh
@@bradwhite5884 True, also, how much you wanna bet that the from the synopsis of the movie, they aren’t gonna use the actual largest animals we know of and just use Spino or something lame like that to appease the mouth breathing JP fans?
@dragodracon7785 Yeah, I am not a huge fan of the synopsis or where they are taking the movie or the plot of the movie either, taking a massive step back from the last movie, u undoing everything and going back to the island for another "run from X dinosaur on an island" movie that can only do it so many times before it goes stale, we have the same plot 5 or 6 times tbh, we need better original movie tbh, a waste on Gareth Edwards talents tbh
Strange as this may sound, but this creature totally matches the description of the "Partridge creek" sighting also in Alaska I believe. It was only seen twice and it was observed charging into a herd of caribou and snatched one up! They stated it was covered in black what appered to be feathers. It was questioned because the witnesses claim while tracking it they saw a line in the snow where it's tail dragged behind and thats not accurate with a T-Rex. However you talked about possible adaptations do to the polar climate, maybe a longer tail would help with balance? You should look into it, I find it hard to believe it would have that many similarities with what you just described. 👍😎
Climate at the North Pole in the Cretaceous was much warmer than today, about 10 degrees C warmer, giving it a temperate climate, more like what we find in Montreal Canada today. Yes you'll get blizzards like shown in the video, but only on the coldest days of the year.
Gigantothermy was for many years the theory of the day and has some merit still. However, the connection with birds and feathers is compelling. And who knows, maybe Nanu could partially regulate its body temp like a great white shark. Or burrowed, perhaps in groups. Great stuff to learn and think about, Thanx.
I wouldn't be surprised if feathers and being able to adapt to diverse biomes are more linked than we currently think. Clearly some dinosaurs were able to handle the coldest regions of their time. Obviously that makes sense, nature fills vacuums. Where there is prey, a predator will adapt to pursue them. Birds Today live in the hottest and coldest places life exists. Perhaps feathers played a roll in all of that?
I’m guessing that dinosaurian dwarfism in the arctic was partially fueled by their ability to feather up. “Borbs” (bird orbs 😊) are a common winter sight. Unlike mammals, who put on their intramuscular fat game, dinosaurs probably just borb’d, and could afford to lose mass for the sake of energy conservation
You are right. There was little or no ice in both poles during the Cretaceous period. Also narrator mentions the Bering strait which is impossible for dinosaurs to have walked through it since it was formed during the last ice age.
Yutyrannus hands down, they were bigger, stronger, and has extremely sharp claws on their usable arms that they are thought to have actually used. The yutyrannus was thought to be at least 30 feet long where as they nanuqsaurus was only though to be between 12 and 22 feet long I may or may not be a paleontology student who specializes in the yutyrannus 😂
I really have to wonder if Nanuqsaurus was descended from a northern population of Daspletosaurus (especially now that it’s been upsized to be around the same size).
I love paleontology and the science of evolution and dinosaurs, but when scientists find skull fragments as relatively small as these ones an extrapolate that to an entire new species inferring 98% of the rest of its skeletal structure, I can't take that seriously
About to write that. This video is misleading click bait at best. How are you going to make a simplified video about this without making sure people understand plate tectonics and the difference in climates from different paleo logical periods. Dishonest
Yes, everything I've ever read about the Cretaceous suggests a considerably warmer earth than we have today. Not as hot as the Permian or Triassic but much warmer than this inter-glacial period and believe the polar regions were ice-free at that time.
You added the feathers and suddenly it went from scary to adorable. So fluffy! Side note: I think this dinosaur suggests that warm-bloodedness was a trait that was present in some larger dinos instead of just small ones. There’s no way this thing was cold-blooded living where it did.
Nanuqsaurus hoglundi is my all-time favorite dinosaur, and I've been obsessed with dinosaurs for most of my life. I've had such a hard time finding information on it, so I really appreciate this video!
0:43 Or worse, the Megaraptors as Maip macrothorax was equally as terrifying to encounter in Late Cretaceous South America due to having a slimmer build, long arms for its size, and large hand claws.
During the time this animal lived (the late cretaceous), the weather in the Arctic region was quite mild. According to sediment core and dendrochronological samples, the average Arctic temperature was around 59°F (15°C). Based on what we now know, the icy landscape imagery in this video is inaccurate to this animal’s contemporary environment.
Interesting! That's actually a pretty big miss. So, since he mentioned an average summer-temp of around +10C, and you mention +15C, then the -30C in winter would be more like -25C, right? Or did you mean an average such temperature of +15C all-year round? So, the summers could have gotten as hot as +30, and the winters only as cold as -5C?? Anyways, would you happen to know if this means Yutyrrannus actually lived in a COLDER climate than Nanuqsaurus? Hence, the feathering on Yutyrrannus makes sense, but it's less likely that Nanuqsaurus would have been feathered? Or was the climate in both environments about the same, and it's still possible that Nanuqsaurus could have been fully feathered?
It's amazing that people continue to portray these inaccurate climates for these dinosaurs. There were no snowy landscapes, or winter wonderlands, anywhere on the planet during the Cretaceous. In fact: During this time period, the poles were so warm, that they supported swamps, bogs, wetlands, woodlands, and subtropical forests. So warm, that crocodilians were able to thrive at the poles. This is all supported by fossil evidence. The Antarctic didn't begin to cool down and freeze until around 30 million years ago, and the Arctic didn't experience the same thing until much later. The planet was truly a Greenhouse Planet during the Triassic, Jurassic, and the Cretaceous periods. And for nearly 20 million years after the extinction of the dinosaurs, the planet was still in a Greenhouse state. The planet didn't begin to cool, and see drastic climactic shifts, until around 35-40 million years ago.
@@Ispeakthetruthify Hmm... I started looking into this, and it seems as if you're correct that the temperature was quite a bit higher, but some of the research in the last 10 years or so don't entirely agree on just how cold it could get. I see some articles mentioning that the average temp for Yutyrannus was actually around +10C, which makes their floofy-ness quite remarkable - if it's that warm, why do they need THIS much covering?? An animal that size will get quite hot. The fluffy down on Yutyrannus is unanimously real though, so that can't be discredited - but there are some intriguing questions here, regarding what other purpose so much covering would serve. However, there does appear to be some evidence that even with this massive green-house effect (it had started to slope off though - the peak was 100 MYA, so late Cretaceous wasn't as hot at all, but hotter than it is today) there were some below-freezing temperatures in the Late Cretaceous Arctic: Spicer et. all (2016) claim that there were regions as cold as -2 to -5C in their paper; "Environmental constraints on terrestrial vertebrate behaviour and reproduction in the high Arctic of the Late Cretaceous". This implies that yes, the scenes in this video are very unlikely - it's not going to get THIS snowy in a region that only goes to -5C on average (during cold season), but there's probably going to be a little bit of snow and frost will be a recurring event. This probably answers my question - was it likely that Nanuqsaurus had downy covering? Yes - because it at least could get below freezing, and since Yutyrrannus which lived in a non-freezing environment, had covering; -2 is plenty colder than +10. However, this is just one article, and it's 8 years old - has their data here been disproven?
If large theropods were feathered, I'd love an explanation as to how they kept themselves clean. With those muscular necks it seems unlikely they could groom themselves as birds do. I've never seen anyone talk about dinosaur self hygiene.
Hmm...! Good question! I've never thought about that... Perhaps that would make pack-life more likely, even? Since it'd be easier to clean each other instead of doing it yourself, in that case. ( a bit like how cats clean their young) This also gets me wondering... if there were other feathered Ornithischians than Kulindadromeus (it seems rather likely), then would they have had the need to clean themselves? What if they were more thick-necked and stiff, like a Ceratopsian? What on Earth do they do then??
Feathering, if there was any substantial amount of it, would have been composed of the simplest structures, not the complex kind seen on most modern birds. Something that cassowaries or emus have. If ratites can clean themselves then so could Nanuqsaurus.
Surely you can deduce a lot about a dinosaur from skull fragments, BUT... when the fragments are THIS small of a portion of the overall skull, how much straight-up guess work actually goes into it? Obviously the overall skull size would be easy enough to give a definitive answer for, but (for example) the unique features at the 4:30 mark couldn't possibly be more than vague hypothesis, right?
Very unlikely but I wonder if they were polar bear clothed, if they also had black skin like polar bears. They would have to have adapted clear ish feathers or incomplete coverage for it to be of much use but still fun to consider. Great dino and vid, find polar dinos particularly fascinating 😊 🦖

Poles can shift locations and axis could have been in different position than today's. Axis is not ridged place, as most geologists assume. So, cold extremes could have been in different area throughout history. And it used to be warmer by few degrees. Arctic regions could have been just like a today's autumn and spring days.

@@GlennKurusuThat's incredible! I feel like polar bears are longer but less robust. Like the difference between a basketball player and an offensive lineman
Polar bear are taller meanwhile grizzly is more muscular
@@WIAProductionsofficial
That explains why Polar bears often flee from Grizzly bears.
@@WIAProductionsofficial What?? Polar bears are literally larger with more muscle mass..? What are you people smoking? I live in Alaska, polar bears are stealth hunters. Completely different than the grizzly. Kodiak bears live on Kodiak Island and Polar bears don’t ever go there…
How adaptable are Tyrannosaur?

That wasnt a yes or no question. Try this one on for size: Are Tyrannosaurs adaptable?

Wouldn't the Cretaceous arctic temperature be ~60°f (~15°c), and without snow? That's what many sources available online seem to say for this time period
You’re absolutely correct. There is just blatant misinformation.
That's an average estimate. Short timescale weather is really hard to determine, so I wouldn't be surprised if it occasionally snowed during the arctic winter nights.
You're looking at the estimated Arctic Ocean temperatures, which would fluctuate a lot less than land temperatures and remain a lot warmer in the winter. The Prince Creek formation seemed to have had a mean annual temperature of 5-13°c from what I can find, depending on the source. With mean winter temperatures being around 2-4°c.
Average temperatures aren’t a good indication of range sometimes though. The climate shifted a lot over a huge time frame and at the very least places inland or at higher elevation would have experienced true winters at least some times. The same was true for the southern landmasses which would have been persistently cool-cold and sometimes extremely cold. Both the extant hot sclerophyllous and wet temperate southern biomes are descended of it. That much is undisputed. That it would be the same in the north doesn’t seem too far fetched even if not as extensive. I don’t know whether the plant fossil record in the north suggests the same but it would be a better indication. They tell us a lot more than the animal record but are often overlooked.
Lack of ectotherm vertebrates suggests to me that the climate at least as cold as today’s Scandinavia or Calgary, Canada
This is why I want to see more videos on dinosaur age polar animals. We hear all about the warm weather regions but freezing temperature regions seem more interesting to me because they are more niche and extreme
So the Gorgosaurus from Walking with Dinosaurs (3D) is in fact this snowy guy
Yes. The documentary version of that film addresses it as such. Even though, Nanuqsaurus was named after its release.
Yes, new genus entirely just wasn't named yet
10:10 I have a different spin. The young left the nursery as soon as they could and moved northward to avoid their elders until they had enough mass to compete with them. Larger prey and milder weather to the south; smaller prey and rougher conditions to the north.
if they moved north from the south that way they would have frozen almost immediately. it had to be a more gradual move than that.
It's not a very good theory. Being that small would have been easy to hide or outrun adults. Kinda like how Komodo dragons do it despite being on a small island.
I like the way you’re thinking!!🧐🤓
You finally gave nanuqsaurus a time to truly shine. Especially with the title and thumbnail many people will see this. You have been to make videos of obscure extinct fauna and their enviornments such as prehistoric australia viral. Many people saw those vids doing those exrinct animals justice as it brought them more fame. I hope you will talk about other animals from prince creek like dromaeosaurus and especially pachyrinosaurus :).
It really paints a great picture to hear the details of the featured species, and the various creatures that lived alongside it. This channel is gold!
So glad to get up this morning and see a video from you. I'm having coffee and listening.
Nah "Magic eraser and straight up erase a huge chunk of your body" is a crazy line

I can only imagine the large but graceful silhouettes of these things lurking across the tundra on a moonlit night.
Nanuqsaurus is one of my favorite Tyrannosaurus beside T.Rex. I would love to see Jurassic World Rebirth use Nanuqsaurus in a blizzard like setting where you can’t see it, but it sees you. That would be a awesome scene.

Yeah, but from what the synopsis of the movie, most of the dinosaurs have died off and moved to warmer climate even though some of the dinosaurs could survive colder climate, but the writers or such don't know much of dinosaurs and this dinosaur would go against that, but love to see it tbh
@@bradwhite5884 True, also, how much you wanna bet that the from the synopsis of the movie, they aren’t gonna use the actual largest animals we know of and just use Spino or something lame like that to appease the mouth breathing JP fans?
@dragodracon7785 Yeah, I am not a huge fan of the synopsis or where they are taking the movie or the plot of the movie either, taking a massive step back from the last movie, u undoing everything and going back to the island for another "run from X dinosaur on an island" movie that can only do it so many times before it goes stale, we have the same plot 5 or 6 times tbh, we need better original movie tbh, a waste on Gareth Edwards talents tbh
hell yeah extinct zoo back with another banger
Crocodile morphs with long legs that chased down prey on land was pretty bangin too
Strange as this may sound, but this creature totally matches the description of the "Partridge creek" sighting also in Alaska I believe. It was only seen twice and it was observed charging into a herd of caribou and snatched one up! They stated it was covered in black what appered to be feathers. It was questioned because the witnesses claim while tracking it they saw a line in the snow where it's tail dragged behind and thats not accurate with a T-Rex. However you talked about possible adaptations do to the polar climate, maybe a longer tail would help with balance? You should look into it, I find it hard to believe it would have that many similarities with what you just described. 👍😎
I didn’t know there were artic dinos until now and this makes me super happy to imagine more fluffy Dinos 🥰

Yea lol

Recently found your channel and I'm enjoying these videos so much!
Climate at the North Pole in the Cretaceous was much warmer than today, about 10 degrees C warmer, giving it a temperate climate, more like what we find in Montreal Canada today. Yes you'll get blizzards like shown in the video, but only on the coldest days of the year.
Been hoping you'd do a vid on this guy! From Alaska and it is one of my favorite dinos since it's discovery! Thank you ExtinctZoo!! Love your videos!!
Please make a video about the Prehistoric South Pole too.

I can't believe that such a terrifying dinosaur could exist in such a cold place. It's truly amazing!
Gigantothermy was for many years the theory of the day and has some merit still. However, the connection with birds and feathers is compelling. And who knows, maybe Nanu could partially regulate its body temp like a great white shark. Or burrowed, perhaps in groups. Great stuff to learn and think about, Thanx.
I wouldn't be surprised if feathers and being able to adapt to diverse biomes are more linked than we currently think. Clearly some dinosaurs were able to handle the coldest regions of their time. Obviously that makes sense, nature fills vacuums. Where there is prey, a predator will adapt to pursue them. Birds Today live in the hottest and coldest places life exists. Perhaps feathers played a roll in all of that?
@@4thdimensionalexplorer Agree.
Watched this the day before I saw an exhibit on the Nanuqsaurus! I was spittin’ facts after watching this!
I’m guessing that dinosaurian dwarfism in the arctic was partially fueled by their ability to feather up. “Borbs” (bird orbs 😊) are a common winter sight. Unlike mammals, who put on their intramuscular fat game, dinosaurs probably just borb’d, and could afford to lose mass for the sake of energy conservation
Thats an impressive amount of research for only having 4 pieces of bone
Aye
It makes you wonder
I thought the Arctic was warmer in n the Cretaceous than it is today.
Still slightly below freezing in winter.
@FirstDagger Finding it hard to find this range in a Google search. I'm finding lows around 40 - 50 F. Any links you can provide?
You are right. There was little or no ice in both poles during the Cretaceous period. Also narrator mentions the Bering strait which is impossible for dinosaurs to have walked through it since it was formed during the last ice age.
@@DecodedDodo
The reason why it’s called the last ice age is because it’s the last one before human civilization. Ice ages happen every 40,000 years.
On the first day of Christmas ExtinctZoo gave to me, a T.Rex but kinda frosty~
Yutyrannus vs Nanuqsaurus who wins?
Neither. They’re all extinct.
Yutyrannus hands down, they were bigger, stronger, and has extremely sharp claws on their usable arms that they are thought to have actually used.
The yutyrannus was thought to be at least 30 feet long where as they nanuqsaurus was only though to be between 12 and 22 feet long
I may or may not be a paleontology student who specializes in the yutyrannus 😂

Yeeaaa
Love ur Videos 🤘🏼keep up the good work. Greetings from Germany :)
I really have to wonder if Nanuqsaurus was descended from a northern population of Daspletosaurus (especially now that it’s been upsized to be around the same size).
I love paleontology and the science of evolution and dinosaurs, but when scientists find skull fragments as relatively small as these ones an extrapolate that to an entire new species inferring 98% of the rest of its skeletal structure, I can't take that seriously
i guess you've just learned about paleontology then
Why is there snow? I’ve never seen anything peer reviewed who recognize the late Cretaceous as mild.. maybe even “warm” by most accounts.
About to write that. This video is misleading click bait at best. How are you going to make a simplified video about this without making sure people understand plate tectonics and the difference in climates from different paleo logical periods. Dishonest
Polar region, slightly below freezing in winter, with low light for 120 days, lat. 80°-85°N. Think where the tip of Greenland is now.
@FirstDagger do you mean one of the tips of *Greenland* ..?
@@mb8787 Thank you, corrected.
Yes, everything I've ever read about the Cretaceous suggests a considerably warmer earth than we have today. Not as hot as the Permian or Triassic but much warmer than this inter-glacial period and believe the polar regions were ice-free at that time.
You added the feathers and suddenly it went from scary to adorable. So fluffy!
Side note: I think this dinosaur suggests that warm-bloodedness was a trait that was present in some larger dinos instead of just small ones. There’s no way this thing was cold-blooded living where it did.
I clicked before I saw the tittle accidently on the notif saw the title and was immediately hooked
Nanuqsaurus hoglundi is my all-time favorite dinosaur, and I've been obsessed with dinosaurs for most of my life. I've had such a hard time finding information on it, so I really appreciate this video!
You have to presume the North Pole was where it is today and the earth had polar icecaps at all.
you also have to presume that the Earths tilt was the same as it is today (it wasnt btw)
0:43
Or worse, the Megaraptors as Maip macrothorax was equally as terrifying to encounter in Late Cretaceous South America due to having a slimmer build, long arms for its size, and large hand claws.
During the time this animal lived (the late cretaceous), the weather in the Arctic region was quite mild. According to sediment core and dendrochronological samples, the average Arctic temperature was around 59°F (15°C). Based on what we now know, the icy landscape imagery in this video is inaccurate to this animal’s contemporary environment.
Interesting! That's actually a pretty big miss. So, since he mentioned an average summer-temp of around +10C, and you mention +15C, then the -30C in winter would be more like -25C, right? Or did you mean an average such temperature of +15C all-year round? So, the summers could have gotten as hot as +30, and the winters only as cold as -5C??
Anyways, would you happen to know if this means Yutyrrannus actually lived in a COLDER climate than Nanuqsaurus? Hence, the feathering on Yutyrrannus makes sense, but it's less likely that Nanuqsaurus would have been feathered? Or was the climate in both environments about the same, and it's still possible that Nanuqsaurus could have been fully feathered?
It's amazing that people continue to portray these inaccurate climates for these dinosaurs. There were no snowy landscapes, or winter wonderlands, anywhere on the planet during the Cretaceous.
In fact: During this time period, the poles were so warm, that they supported swamps, bogs, wetlands, woodlands, and subtropical forests. So warm, that crocodilians were able to thrive at the poles. This is all supported by fossil evidence.
The Antarctic didn't begin to cool down and freeze until around 30 million years ago, and the Arctic didn't experience the same thing until much later.
The planet was truly a Greenhouse Planet during the Triassic, Jurassic, and the Cretaceous periods. And for nearly 20 million years after the extinction of the dinosaurs, the planet was still in a Greenhouse state. The planet didn't begin to cool, and see drastic climactic shifts, until around 35-40 million years ago.
@@Ispeakthetruthify Yes, indeed.
@@Ispeakthetruthify Hmm... I started looking into this, and it seems as if you're correct that the temperature was quite a bit higher, but some of the research in the last 10 years or so don't entirely agree on just how cold it could get.
I see some articles mentioning that the average temp for Yutyrannus was actually around +10C, which makes their floofy-ness quite remarkable - if it's that warm, why do they need THIS much covering?? An animal that size will get quite hot. The fluffy down on Yutyrannus is unanimously real though, so that can't be discredited - but there are some intriguing questions here, regarding what other purpose so much covering would serve.
However, there does appear to be some evidence that even with this massive green-house effect (it had started to slope off though - the peak was 100 MYA, so late Cretaceous wasn't as hot at all, but hotter than it is today) there were some below-freezing temperatures in the Late Cretaceous Arctic:
Spicer et. all (2016) claim that there were regions as cold as -2 to -5C in their paper;
"Environmental constraints on terrestrial vertebrate behaviour and reproduction in the high Arctic of the Late Cretaceous".
This implies that yes, the scenes in this video are very unlikely - it's not going to get THIS snowy in a region that only goes to -5C on average (during cold season), but there's probably going to be a little bit of snow and frost will be a recurring event.
This probably answers my question - was it likely that Nanuqsaurus had downy covering? Yes - because it at least could get below freezing, and since Yutyrrannus which lived in a non-freezing environment, had covering; -2 is plenty colder than +10.
However, this is just one article, and it's 8 years old - has their data here been disproven?
Man Tyrannisaurs look so pattable with all that floof
If large theropods were feathered, I'd love an explanation as to how they kept themselves clean. With those muscular necks it seems unlikely they could groom themselves as birds do. I've never seen anyone talk about dinosaur self hygiene.
Hmm...! Good question! I've never thought about that... Perhaps that would make pack-life more likely, even? Since it'd be easier to clean each other instead of doing it yourself, in that case. ( a bit like how cats clean their young)
This also gets me wondering... if there were other feathered Ornithischians than Kulindadromeus (it seems rather likely), then would they have had the need to clean themselves? What if they were more thick-necked and stiff, like a Ceratopsian? What on Earth do they do then??
Ever see a vulture?
@@patriciaaturner289 Not personally but on videos. What about them.
@@cerboris521 They don't have feathers on their necks
Feathering, if there was any substantial amount of it, would have been composed of the simplest structures, not the complex kind seen on most modern birds. Something that cassowaries or emus have. If ratites can clean themselves then so could Nanuqsaurus.
Surely you can deduce a lot about a dinosaur from skull fragments, BUT... when the fragments are THIS small of a portion of the overall skull, how much straight-up guess work actually goes into it? Obviously the overall skull size would be easy enough to give a definitive answer for, but (for example) the unique features at the 4:30 mark couldn't possibly be more than vague hypothesis, right?
I wonder if it’s feet could have a similar circulation to geese and other birds that live in colder environments year round
I was thinking something very similar. Could it have been warm-blooded similar to how certain sharks.
@@Mukti0033Most dinos are already warm-blooded...its an ancestral archosaur trait that crocodilians lost

Very unlikely but I wonder if they were polar bear clothed, if they also had black skin like polar bears. They would have to have adapted clear ish feathers or incomplete coverage for it to be of much use but still fun to consider.

I find it fun how through Nanuqsaurus, i got interested in Inuit culture and mythology
Poles can shift locations and axis could have been in different position than today's. Axis is not ridged place, as most geologists assume. So, cold extremes could have been in different area throughout history. And it used to be warmer by few degrees. Arctic regions could have been just like a today's autumn and spring days.
