When Dinosaurs Chilled in the Arctic

[@eons]

Hey Eons viewers--you may be scrolling down to the comments to ask what's going on with the °F side of our thermometer graphics in this video. And we're not sure what happened either! But we are sorry for the error. To clarify: ‣The mean annual temperature in the Cretaceous Arctic was 6.3 °C / 43.3 °F. ‣The mean annual temperature in the northernmost parts of Alaska is -12 °C / 10.4 °F. ‣The mean temperature in the warmer months of the Cretaceous Arctic was 14.5 °C / 58.1 °F ‣The winter temperature in the Cretaceous Arctic could drop to -10 °C / 14 °F

[@Ezullof]

"reptile-like" isn't a thing though. That's how we categorized animals like a century ago. We also stopped considering that animals had to be either homeothermic or ectothermic, or even that all dinosaurs regulated their body temperature in the same way. There was likely some variation between different dinosaur species.

[@asfandyarmuneeb7263]

Well there are reptiles like wall lizards that are also warm-blooded

[@raminagrobis6112]

@@Ezullof I think you put too much weight in the words I used. I am a biologist with a PhD and didn't get my degree a century ago btw so you don't need to be condescendent with me. I did use the term homeothermic, not endothermic deliberately. Of course things are not as simple and dichotomic as that. I meant, in a short paragraph that precluded all nuances, that dinosaurs living in the polar regions were likely not reptile-like, meaning ectothermic in a broad sense. I don't see why you made such a fuss unless you wanted to assert you know better. Not cool. The thing is, theropods included feathered dinosaurs, and the prelude to birds which are definitely endothermic. Feathers are a feature of endothermy, and this is definitely not "reptile-like". This is YT and the term I used is perfectly all right.

[@hues_of_neon]

Hey, one of my professors is featured in this episode! : D Also I think its worth noting that an increased size in Arctic Troodon could possibly have helped it maintain body heat by decreasing the surface area exposed to the cold surroundings while maintaining a large volume.

[@asimian8500]

However, the Hadrosaur wasn't different from its southern and warmer cousins. We have to be careful here. There's a lot more to arctic dinosaurs than just a higher ratio of surface area to volume ratios. Dinosaurs were most likely warm blooded due to studies of thinly sliced bone samples of dinosaurs from baby-to-juvenile-to-adult which indicated rapid growth as well as other factors indicating being warm blooded. As for larger theropods...just because we haven't found bigger ones doesn't mean they didn't exist. Absence of evidence isn't evidence of absence....as future discoveries could indicate larger theropods.

I saw a documentary on Arctic dinosaurs and my memory was that the Arctic had a temperate climate like Ottawa, Canada. It was hot in the summer and had cold snowy winters and the dinosaurs adapted. Some moved further south where it was warmer and had no snow in the winter to look for food. Others just stayed behind. The leaves in the fall changed color and in the spring, the flowers budded.The Arctic had weather like Florida, South Carolina, and Georgia 55 million years ago with swamps, ferns, crocodiles, turtles, and some sort of lemurs because the Co2 was very high.

Larger body size also provides a greater mass to surface area ratio, helping the animal retain heat in cold weather.

[@limiv5272]

Exactly what I thought. I was surprised it was never mentioned

[@ManuelFlores-ct3xy]

Larger body also means blood takes longer to reach every end of the body and dinosaurs can’t make a fireplace it’s literally below 0• and if it’s an ice age they would have to find new ways to get warm if there body doesn’t create enough heat to protect them from cold especially if they are cold blooded

Love this channel. Been binge watching the past few days. Gotta love lockdown. Learning about new things every day!

[@milk7803]

Can we just appreciate the effort put into this video?!

[@veggieboyultimate]

Isn’t the name Troodon considered an invalid name? Also, the dinosaurs managed to do insular dwarfism and gigantism on mainlands rather than in islands.

[@lizardzilla]

Yeah troodon is now considered invalid

[@IAmAGyroGamer]

It's considered invalid due to the undiagnostic nature of the holotype specimen found. Now Troodon has split into two taxa: Latenivenatrix and Stenonychosaurus.

[@Devin_Stromgren]

In this case the gigantism may be less insular, and more insulate. A larger body can retain heat better. It's why whitetail deer are substantially heavier in Minnesota than they are in Texas.

[@daliborjovanovic510]

Yes. Both Troodon and Stenonychosaurus are also from the Campanian age, while the Arctic troodont is from the Maastrichtian, meaning its likely a separate genus altogether.

[@paulkuchnicki6404]

Dalibor Jovanovic Or they could simply name the Maastrichtian troodontid Troodon for everyone’s convenience.

[@benhancock8143]

So me and my son watched this he’s 2 years old and he asked if we are going to see the Troodon station from Dinosaur train! 😜

God I remember that show. I used to be obsessed with it when I was in 1st grade.

I would love to see Eons tackle the evolution of reindeer/caribou. They have so many adaptations for life on the tundra, and were probably one of the most important prey species for Upper Paleolithic humans.

[@stonedalldayjedi533]

Thank you for having great audio. It's perfectly clear and loud, I appreciate it

4 months of darkness? That’s northern Sweden for you. But more like 6

-10 C tho? Practically summer.

That's what I was thinking. At -10° we go outside to enjoy the heat.

These temperatures are similar to the Great Lakes region today. It's an area with plenty of reptiles that do just fine.

[@benjamino.7475]

I wonder if any dinosaurs lived in Antarctica? It would have been warmer there during some periods than today. Just imagine which kind of new fossils we might discover there once the ice unfreezes completely in a few decades.

[@docteurflou]

Well, bird are dinosaurs, so you can say that there is dinos living in Antarctica right now !

[@pedroarjona4618]

They were several species of non avian dinosaurs living in Antartica, there is even a Field Museum exposition about them touring the US, although the schedule is uncertain because of the current situation

[@zddxddyddw]

Many fossils have been found in Antarctica indeed. The place is not completely covered in ice, specially during the summer. Many places, mostly on the coast, are iceless and can be searched for fossils. There are currently three Antarctic dinosaurs known: Cryolophosaurus, Antarctopelta and Glacialisaurus.

[@francepri2415]

Troodon is not a valid genus anymore. It has been splitted in two taxa: Latenivenatrix and Stenonychosaurus Greetings👋👋

[@joemama103yearsago4]

Fran Cepri thx brother

[@antoniocenteno1483]

I hate paleontology sometimes, you just get used to something and BOOM, Crocodile tail Spinosaurus; now this two genre split with names out of a Jurassic World scientists

[@alioramus1637]

But it was troodon formosus that was found to be invalid. The alaskan troodon has yet to be named so it's informally called alaskan troodon. it's not the same animal you are thinking of.

[@Lakhshamana]

Troodontidae is still a quite valid family I think

[@94sweetmochi]

So Troodon were the equivalent of modern wolves? Thats cooler than I thought!

[@sammuelmccall56789]

Wolves are the equivalent of ancient troodons

[@Zimisce85]

Well, some fancied them to be the equivalent of humans, or at least of early primates.

[@dougules]

Does that make Nanuqsaurus the ancient equivalent of polar bears?
