Got 3 ads in this one video, keep up the good work, Polaris. I'm really glad the algorithm picked your channel up, you are my favourite youtuber that talks about this sort of content.
Dr. Polaris I'm going to start showcasing your channel on my Instagram. I have less than 100 followers, and most of them are young people but knowledge is power, and dinosaurs are awesome
while looking at this video i just realized something about dinosaur paleoart. The modern birds like chickadees/robins and countless other small birds have dark almost pitch black looking eyeballs. And archasaurs like crocodiles and aligators have darker eyes too. Yet you also get creatures like hawks that have clearly defined pupils. I am mostly curious would dinosaurs have pupils?
Like birds, dinosaurs where insanely diverse in their biological structure so it's possible some had eyes like songbirds and crocs and others had eyes more like (modern) raptors.
When I can't sleep at night, I watch Dr Polaris and relax. I soon fall asleep and sometimes dream of dinosaurs. Dr Polaris I'm not calling your videos boring, in fact I find them very interesting, it's just that your voice is so soothing and the images you use are relaxing too. Like a paleo David Attenbrough
Another excellent video on dinosaurs I had little knowledge of. You have your well thought out Alter Earth series, but I wonder: The end Cretaceous extinction occurs, but mammals do not evolve to dominate the planet. Who are the candidates to replace the dinosaurs, pterosaurs and sea reptiles?
Love that you cover so many little known dinosaurs, I can say without a doubt you have some of the most comprehensive content for lots of the animal groupings you cover on this platform.
Bizar animals indeed. They almost start to look like some of the Triassic proto-dinosaurs again (i.e. dinosauriform archosaurs). I can see why classification of incomplete remains was somewhat problematic. They're like Dromaeosaurs, and Ornithomimosaurs, and generic Coelurosaurs, all in one somehow. As to Masiakasaurus and its goofy teeth, it's interesting to speculate on what it used those for. I think the idea that it hunted small, burrowing prey is not at all far-fetched. Most small animals would indeed burrow, including reptiles, mammals, and some birds. Its skull doesn't look very robust; fenestration is pretty significant, especially in the antorbital. But the eye socket is also quite large. Perhaps it relied a lot on its sense of smell and sight, which, again, might have aided in locating and pinpointing fast moving, small prey items in holes or burrows in the soil. The portruding teeth are so weird that it almost seems as if that's exactly what they were being used for. The slender head entering into burrows, and the teeth allowing it to grab hold of animals in tight spaces. Or maybe scraping insect larvae out of tree trunks. I mean, we really don't know at this point, and I'm not sure what other (small) animals coexisted with Masiakasaurus. You'd have to reconstruct its ecosystem and the many animals that lived therein to get a better idea of the possibilities. The fossil record is so fragmentary though; what wondrous worlds must be entirely lost in time by now..? No matter how much we discover and learn, there will always remain that mysterious aspect, like a formless shape in the fog. It's almost poetic, or romantic, and it draws us in, and we want to give it a name and come to know about it, but the deep past is like a bunch of grapes, hanging just beyond our reach. No matter how much we stretch our arms, there's an element to it that will always elude us; always slipping through our fingers, and we cannot obtain it or grab hold of it. These fossils are mere windows into the past; glimpses and echoes, beautifully distorted, wonderfully bizar. Hmm.. sorry, got a little bit carried away there lol.
How about covering the stegosaurs in the near future? They had a ton of genera in the late Jurassic, but seemed to fall off a cliff in the early Cretaceous.
Haha yeah, I grew up playing Wrath of Cortex on the PS2 and have always thought it had a great soundtrack. Arctic Antics just fit perfectly for intro music.
3:17 Why is there a human skeleton mounted like that in there? I get it maybe for a size comparison, but it looks like a guy on acid trying his best to impersonate a theropod.
Noasaurs actually survive into modern times in Madagascar and Australia while their Abrlisaurid cousins are extinct. They are not exactly common but remain as specialised carnivores and piscivores.
i know this is about the dinosaurs but just immediatly what caught my attention was the random human skeleton in the deltadromeus display lol, what drugs were involved in putting that there just to show the posture.
Mashikasaurus' teeth look like they could be used for pecking fish out of water. presumably after chasing them. Though I love the image of them pulling their pray out of dens. 👍as always. More Noasaurids please their interesting, their speed does imply flocking ,especially in herbivorous spices
Noasaurids survived the Jurrasic. So, they all died out then? No, they survived to the end. Asaurids survived then? Noasaurids survived, there were no Asaurids! There weren't any but they survived? Noasaurids, Noasaurids, not Asaurids! I didn't mention Notasaurids but did they survive too? Oh, I give up!!
*Dr. Polaris*: have you considered modern pterasaur sightings as ancient biological UFOs that evolved to mimic the pterasaur before they got wiped out at the end of the Cretaceous? I propose they are insect-based and simply outlived the creatures which they learnt to mimic. Problem solved. Sea monsters and giant wurms etc. would be the larval stage of other biological UFOs. They would have evolved on the continent of Antarctica as it drifted over the South Pole.
I'm curious, would these dinosaurs have had feathery integument? 'Cause looking at the group they belong to + relatives, they look like (to my limited research at least) to have likely been scaled and lacked feathers. However, a lot of the artwork in this video shows them with feathers, but it's still very 50/50 in reconstructions, and as I'm using these critters for a spec evo project, I'd like to know your thoughts on this!
4:18 Is it just me, or does the sllhouette representation of the human female look rather odd? Which subspecies of hominid has those long protrusions at the heel? But seriously, if it is there for scale, why is she wearing stylettos?! lol
Speculative ones based on well known anatomical features that identify the fossil animal as part of a distinct family. Those vertebrae possess typically noasaurian traits and judging from their relative size we can get a fairly good (though far from perfect) idea of what these animals were like in life.
As much as a viscerally dislike the idea of dinosaur feathers I have to admit they are most likely valid and these dinosaurs really look like naked chickens they probably need feathers. Has any research on that been done?
A great many Limusaurus fossils are found crammed together in deep circular pits along with the remains of other animals (including Guanlong). It is suggested that these pits are the footprints of a gigantic sauropod which churned up the mud as it walked by and created a series of lethal traps for smaller animals. Google “dinosaur death pit”.
Got 3 ads in this one video, keep up the good work, Polaris. I'm really glad the algorithm picked your channel up, you are my favourite youtuber that talks about this sort of content.
Ahh thank you so much!
I got two unskippable 15-seconders before the video. Was worth it, as always.
Really interesting and underrated dinosaurs, I really hope we will learn more about them in the future
Imagine what noasaurs would have evolved into if the k/pg extinction never happened like with your tetraprotodon in alter earth
Exactly, I also have a living genus of Noasaur on Madagascar that is a specialised piscivore.
Sir you explain very good. Love your videos
Thanks!
This looks like a goofy side character from a Pixar Film.
Good point. Noasaurids are quite comical looking animals, what with their weird teeth and tiny arms.
I always get so cherry with your intro song 💛
Dr. Polaris I'm going to start showcasing your channel on my Instagram. I have less than 100 followers, and most of them are young people but knowledge is power, and dinosaurs are awesome
Your videos are great, pretty much the only channel on UA-cam that provide info on such unique groups!
Thanks, that was always my aim for this channel.

And archasaurs like crocodiles and aligators have darker eyes too. Yet you also get creatures like hawks that have clearly defined pupils. I am mostly curious would dinosaurs have pupils?
I suppose a better way of wording it is, would they have clearly defined reptilian pupils or more bird/arkasaur like pupils?
I think so.
Like birds, dinosaurs where insanely diverse in their biological structure so it's possible some had eyes like songbirds and crocs and others had eyes more like (modern) raptors.
I love the Noasaurids. They were widespread in Gondwana and especially South america and there are remains of them even in Australia. Awesome segment!
Thanks, I really like Noasaurids as well.

Ah that's great to hear. I'm glad my videos can both help you fall asleep and spread information about ancient animals!
This is another awesome Dr. Polaris video on these weird strange,and cool prehistoric creatures.
Also I wish y'all a good day,you awesome peps.
Another excellent video on dinosaurs I had little knowledge of.
You have your well thought out Alter Earth series, but I wonder:
The end Cretaceous extinction occurs, but mammals do not evolve to dominate the planet.
Who are the candidates to replace the dinosaurs, pterosaurs and sea reptiles?
Interesting question. Perhaps the Squamates could finally get a shot at world domination!
Masiakasaurus is one my favorite dinosaurs!
One of mine as well!
Love that you cover so many little known dinosaurs, I can say without a doubt you have some of the most comprehensive content for lots of the animal groupings you cover on this platform.
Excellent video as always Dr. Polaris 😁. Is it possible that you could make a future video on the brontotheres or Chalicotheres?
Both great ideas. Funnily enough someone else suggested the Chalicotheres as a future topic as well.
Your videos are like gold ! You have information that's completely original to You Tube. I love this stuff!
Wonderful video. What an amazing creature. 👏🏼
I love the tiny arms..

As a kid, I used to call Noasaurids 'Fake Raptors' 😁
Gotta love your videos. Calming and informative, exactly what i need for late evening hours to relax ^^ Have a good one and stay healthy
Yet another fascinating weird ball. Thanks!
I love your videos, although I was shocked when I recently discovered your theme tune comes from crash bandicoot of all places.
Haha yeah, I grew up playing Wrath of Cortex on the PS2 and have always thought it had a great soundtrack. Arctic Antics just fit perfectly for intro music.
Nice to see some love and care for non-tetanuran leggy bois!
3:17

I know it’s a very strange detail. Did a double take when I first saw the picture but was too good not to include!
Impersonating theropods is great fun, a good workout too
@@JoshKnoxChinnery not so much for the arms though
Quite an odd group, that I wonder what your position on their success in your alternative speculation project is
Noasaurs actually survive into modern times in Madagascar and Australia while their Abrlisaurid cousins are extinct. They are not exactly common but remain as specialised carnivores and piscivores.
Finally detailed video on them
What a fast videooutput
Such an overlooked and mysterious group
i know this is about the dinosaurs but just immediatly what caught my attention was the random human skeleton in the deltadromeus display lol, what drugs were involved in putting that there just to show the posture.

👍as always.
More Noasaurids please their interesting, their speed does imply flocking ,especially in herbivorous spices
Plz Make A Video About The Beast Of Gevaudan Or The Killer Crocodile Gustave (I Know Gustave Is Not An Cryptid)
Both are good ideas!
@@dr.polaris6423 Thanks
Can you make a video for the very underrated Astropotheres of South America or maybe the Sebecids of South America
Ahhh Dr.Polaris hello my good sir
Do you plan on covering chalicotheres? Can't seem to find much info on them, but they seem very interesting.
They certainly are interesting. I’ll definitely cover them in the future.
3:04 tu sei lei, tu sei lei.. 🎶🎵🎶🎵🎶
nice video
Drypyosautoides is considered a abelisauroid, if so if would be the biggest
I wonder what kind of hunting strategy they had a long with what they could have been hunting. I assume small and really quick creatures.
Noasaurids survived the Jurrasic.
So, they all died out then?
No, they survived to the end.
Asaurids survived then?
Noasaurids survived, there were no Asaurids!
There weren't any but they survived?
Noasaurids, Noasaurids, not Asaurids!
I didn't mention Notasaurids but did they survive too?
Oh, I give up!!
Do you think they were affectionate pets? I bet they'd be fun to take to the park with a frisbee
indeed, they are a very interesting group, and need some good attention.
good show
When I found out about these guys I was like “that’s a strange dinosaur…, group of dinosaurs”
Noasaurs were weird. We got one with forward pointing teeth and another one with an feets that walk on an single toe. Functional toe.
Does anyone know who the artist on the model at 2:15 is, it’s so pretty I’d love to see more of their stuff
Ah yes, the ceratosaurian-equivalent to coelurosaurs.

( 7:55 pause mode ) wait why there was raptor toe claw is this some sord of error 🤔😅 ?
Why did you private the last one?
Sorry about that. I made a mistake on the thumbnail so I had to take it down.

Do you plan on covering more cryptids anytime soon?
4:18 Is it just me, or does the sllhouette representation of the human female look rather odd? Which subspecies of hominid has those long protrusions at the heel?
But seriously, if it is there for scale, why is she wearing stylettos?! lol
What about Ceratosaurus itself?, u didnt have this one in ur video
3:19 funny!
@dr.polaris u should have a discord server
3:14
Why did they have to pose the human skeleton like that??
How fun!
Reupload?
Yeah there was an error with the thumbnail. Had to change it quickly!
@@dr.polaris6423 you could have just fix it instead of reupload it.
I’m not feeling the whole scutes with feathers thing.
Sorry, doc, but I don't think you brits are in position to laugh at anyone's dental condition.
Haha, that's a bit of a myth perpetrated by Americans I'm afraid.
Wait, is it really pronounced "muh-she-kuh" and not "may-zee-ak-uh"??
So you can make whole creatures out of four bones? Pretty shaky.

Ok dude the fossils were in mud so safe to say they died in a mud flood.
A great many Limusaurus fossils are found crammed together in deep circular pits along with the remains of other animals (including Guanlong). It is suggested that these pits are the footprints of a gigantic sauropod which churned up the mud as it walked by and created a series of lethal traps for smaller animals.
