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.

[@yusufg6998]

I agree

[@CCNorse]

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.

@ Significantly Smaller? They’re both estimated to be around 8 to 9 meters long & weigh 2 or 3 tons.

[@brassbuckles]

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.

[@frumpkin9282]

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.

[@Freshbott2]

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.

[@BanilyaGorilya]

Imagine my father’s silence when I learned him that the T.Rex for the sake of filmmaking was made slow and essentially dumb for its visual acuity and sense of smell but if made science accurate, potentially we’d have Rex stalking the characters, ambushing the protagonists through bushes, low pulsating growl, and can sense our characters for miles keeping pace at every turn.

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.

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.

[@predabot__6778]

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?

[@Ispeakthetruthify]

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.

[@jamesaron1967]

@@Ispeakthetruthify Yes, indeed.

[@predabot__6778]

​@@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?

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

[@FirstDagger]

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.

[@mb8787]

​@FirstDagger do you mean one of the tips of *Greenland* ..?

[@FirstDagger]

@@mb8787 Thank you, corrected.

[@jamesaron1967]

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.

If the white feathered illustrations are anywhere close to accurate then this is probably my new favorite fashion dinosaur

[@evodolka]

I find it fun how through Nanuqsaurus, i got interested in Inuit culture and mythology

[@ExousíaTM]

Thanks to one of Deadsounds dinosauria episodes, "Our Frozen Past" we can now learn more about the Nanuqsaurus :>

[@Hiddensecret9]

Plot twist: the T-Rex is actually just trying to ask for directions. But hey, if you’re good, I’ll let it know you’re chill about being its next snack.

[@stickybird9725]

On the first day of Christmas ExtinctZoo gave to me, a T.Rex but kinda frosty~

[@AllfahTradez]

i read title, i see extinct zoo, i smoke spliff i already know im in for a banger

[@joseluiscalixto5651]

Good summary about Nanuqsaurus hoglundi, the Arctic King of the Late Cretaceous.

[@corinneaggar9755]

Most enlightening thank you for putting this together 👍

[@RiniUsagi]

Me, who lives somewhere where the winter temps regularly hit -30C and we get at least two weeks a year where it drops to -40C-45C: I could have been this dinosaur

[@davidc5191]

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.

[@a.s.raiyan2003-4]

What if this feather was also white as snow? We're talking about an apex predator with perfect winter camo.

[@MasterFlores35]

I really hope they find more fossils on this Dinosaur. Would love to see an updated vid eventually

[@radmanstan413]

I came here thinking this was a dinosaur cryptid video, stayed for the dino knowledge

[@RPSchonherr]

Probably what they think are young are the full grown ones as arctic conditions would tend to smaller body size and I would also guess that they hybernated during the winter but the unfortunate ones we found went to sleep and never saw a thawing before their stores of energy ran out and they died under the ice. It could have been a long winter of a few years before another thaw came allowing decomposition to start.

[@drsquash2003]

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

[@BloodDragon-rp4xc]

dead sound referenced, you are a man of more culture than the old beasts

[@Mr.Generic__]

6:53 seeing all these pictures of them covered in long fur smh. These are reptiles, for the best representation of what they’d likely look like look at birds. Since they don’t need to fly my own personal head cannon is that they had big ol’ fluffy white feathers. Like a snow owl or baby penguin. Perfect camouflage, keeps the cold air off their skin and is waterproof as long as you don’t completely soak it. Better yet this means it would look like a marshmallow t-Rex and I now have a new pet for a dnd npc.

[@pms9838]

I would like to understand more about the ecology of the area supporting it and it's food source.

[@LadyhawksLairDotCom]

Thanks for these videos. One small note: carry-on is what you bring on an airplane; carrion is dead meat, and it's pronounced "keh·ree·uhn". I hope this is helpful and not annoying.

The polar bear lizard is an insane title to hold.
