Fun Fact: When the mother Troodontid climbed on top of their den, it actually created a sound that mimicked a baby Pachyrhinosaurus, causing the herd to come to their aid.
Nah really?
@@Themanhandler228yep the creator said it himself
@@poojathapa4940 it seems like you are brain dead because of your lack of detecting my sarcasm
Well it resemble mockingbird or lyrebird
*Clever Girl.*
The troodon mother was mimicking the Pachyrhinosaurus calls.
How to make a good paleo doc
1. Make it good in accuracy
2. Include animals that aren't really acknowledged much
3. Have at least 3 scenes of baby murder
You need way more than 3 I think at least 13
A couple of things:
- The Nanuqsaurus and Daspletosaurus differing in skin coverings despite being closely related isn't that strange, plus we don't have any concrete evidence that Daspletosaurus wasn't feathered itself.
- The "Troodon" is mimicking the cries of a baby Pachyrhinosaurus, the mimicry was already alluded to early on and you brought attention to it. Weird that you would miss that.
I also don't think mimicry is really that far-fetched of a behaviour for an animal like Troodon, unlikely sure, but not entirely impossible or unreasonable.
Yea just take a look at lions and snow leopards that are literally in the same genus
@@BermudaHawk47tigers have also been known to mimic deer sounds despite not being birds at all.
@@BermudaHawk47it’s not like tigers are scaly while leopards have fur. It’s not exactly the best comparison
@@JurassicReptile ya but the thing is snow leopards and Lions are in the same genus, yet look different, adapted to their environment in their own ways. Daspletosaurus and Nanuqsaurus are in a different GENUS in the same subfamily, probably allowing a lot more biological diversity between the two. Like if their ancestors had a little bit of protofeathering along parts of it’s body and as the species expanded throughout many different environments with different climates and other conditions, one population may evolve more feathering to combat the harsher climate, granting Nanuqsaurus. While another population evolves less feathering and other traits for a calmer climate, branching off to Daspletosaurus. Maybe a better example is us and Gorillas, gorillas grew larger with more fur with the dense jungles of the Congo. When early humans evolved much leaner and more endurance based bodies for the grasslands of Africa. We’re in the same subfamily as. Gorillas btw (Homininae). Different environments can make close relatives look pretty darn different to each other. Not saying I’m right, but it’s possible. Think David went a bit overboard with the intense feathering, but it probably had a little bit at least.
@@JurassicReptile That hinges on the idea that Daspletosaurus didn't have feathers of some kind, though. We know it wasn't extensively feathered, but that doesn't mean it didn't have finer feathering, like the hair of an elephant for example. We simply lack the evidence to say something as conclusive "Nanuqsaurus didn't have feathers" because we don't even know for sure that it's close relatives didn't.
I think you missed that the trodontid was mimiking the pachirinisaurus help call to defend itselve
Congrats on saying ‘Troodontid’ instead of _Troodon_ which is a dubious genus.
@@rhyusbrand8311 I love dinos I woud hate making that mistake
9:16 Usually your points are amazing, but dude. Mammoths and elephants. Sure, elephants do have very fine sparse hairs, but Daspletosaurus could (not for certain, but could) of have had very small and sparse quill nobs. Feathers and hair seem fairly easy to gain or lose, depending on environmental circumstances.
I loved seeing feathered dinosaurs in the snow during the second short film of the series! The colours and music really helped to bring beauty and intensity to this one, I love this series so much and hyped to see your reviews on the other three short films.
the "troodon" wasn't screaming, it was imitating the sounds of the baby pachyrhino
12:55 its not screaming from being upset. It was mimmicking the distress calls of the young pachyrhinosaurus from earlier, thats why it was calling, and why the herd comes in. This was already preluded earlier in the episode with it copying the noise of falling icicles, kindof surprised you didn't notice.
Yeah I did notice after the fact but forgot to comment on it. Oopsies
@@redraptorwrites6778 Fumbled a bit there bud
@@redraptorwrites6778happens to the best of us
@@redraptorwrites6778here is a comment for the dinosaur planet video, tarascosaurus is now a valid genus, I went to Wikipedia and it did not say anything about it being invalid.
daspletosaurus and nanuqsaurus being depicted with vastly different integument was interesting. as it stands currently we do not have skin impressions on tyrannosaurids that are very large relative to their body size, all the impressions we have are smaller than a human palm. the skin impressions we do have also fossilized both in areas unlikely to have fluff and such that any fluff would not have been preserved if present. however, feathered dinosaurs today don't just lose all their feathers because they evolve different sizes, or in different climates. afik the larger dinosaurs got the shorter and more form fitting their feathers got, rather than their feathers staying at the same length to body size ratio of smaller ones.
Yea fr, just take a look at the difference between lions and snow leopards who are literally in the same genus
This guy does amazing videos! His anthropomorphic dinosaur show is really cool though obviously less on the accuracy front, also I just watched the first episode of Life on our planet, a little disappointed with the cgi and continuity. But I have just come off a PP high (prehistoric planet which probably shouldn’t be shortened)
some people shorten it to “php”, if that helps
About feathers: we have not any good comparision in novadays birds, but there are some from Mammals. For example we have Mammuthus. In the same genus we have very fluffy Woolly mammuth and also more primitive species from Africa with likely no more fur than african elephants. So it could look similar with tyrannosaurids from different climates, especially from two different genera. That's my point
In terms of animals of the same genus being either too similar or too different, i think it's important to remember that there isn't really any rulse on that. You can have basically idetical-looking rats be from completely different genera but then have a genus like "panthera" where all the species in it are wildly different
No wonder many of the panthera cats can breed with each other, despite looks so different from each other. Same with wolves with jackal or coyote that can creating hybrid
I would love to see a Review on When Dinosaurs Ruled (2000) with Jeff Goldblum
Since Troodon is a wastebasket then should we even be calling the group Troodontids?
I think we can keep calling them troodontids. Titanosaurus is a dubious genus, yet we still call the clade Titanosauria. Both names are so old that I don't think anyone is gonna bother trying to change them.
@@Bagelgeuse I should’ve known this already but I didn’t know there actually was a dinosaur named Titanosaurus.
@@tobiasedwards2643 It's only known from a handful of bones so don't worry, you didn't miss much.
As far as the feather point think about elephants and mammoths, one is very hairy and the other isn’t
I've be waiting for episode 2!
Tom Holtz noted the polar opposites of integument in the babarussa and red river hogs despite being closely related and living in the same environments. So yeah, integument can vary drastically.
fried rice at denny's
Thanks Beth 😑
sounds like a weird Fnaf fangame
WAS THAT THE BITE OF ‘87?!
Guys, he probably knew the Troodontid was mimicking a baby Pachyrhinosaurus. UA-camrs do this all the time to get more comments and boost the algorithm.
This truly is some of the best paleomedia I’ve seen on the internet.
Honestly 35-55 degrees can be quite cold especially in the shade and if there’s a constant breeze. So I could still see dinosaurs in that environment having feathers
Another thing with Nanuqsaurus, you didn’t mention that it wasn’t a dwarf tyrannosaurid as once believed to be, but was instead comparable in size to Albertosaurus and Gorgosaurus, being around 8-9 meters long and around 2-3 tons in mass as opposed to the 5-6 meter size originally estimated for that genus of dinosaur.
Was that the bite of 87 ? 🤣
Believe in Troodon
It's probably the best dinosaur animation I've ever seen
My poor virgin eyes have to see a child get murdered. This sentence was inspired by Red Raptor
Was that the bite of 87?!
First of all its awsome u have a wife now congrats pally and I WENT TO THE AQUARIAM TODAY SO THATS COOL
Please make a review on the Fnaf movie please 🙏
Red could you dona sorteo of accuracy review on the isle ?
Raptor, can you do a review "Life on our planet"?
Could you review “ sharp teeth”? Less from an accuracy perspective and more for the themes?
Unrelated but would you ever make a tier list about which dinosaur has the best persevered specimens and specimen amount? (maybe have the contender list be the dinos from Jurassic World evolution 2 or Ark survival evolved)
Can you take a look at Dinosapien
Troodon could be a real genus, but it is more of a waste basket taxon, but troodon will be a great animal.
Troodon does exist, troodon is not a waste basket taxonomy but instead an interesting taxon.but madeupornis birdii is the real waste basket taxon
I would point out about the different integument on the despletasaurus versus the nanuqsaurus isnt that strange just because they’re closely related with the example of humans and chimps (sure we’re mammals not reptiles but still) - we share 98% of our coding genome and yet, totally different hair covering, even if its the same number of hairs it still is different coverage for a different niche, despite us being closer to each other than either is to gorillas or anything else by extension. Also example of asian elephants and mammoths works too in a similar fashion. So it seems reasonable to me.
Was that the bite of 87 million years ago?
I am actually a youtuber who makes a few dinosaur documentaries using animatronics. I was wondering if you could review them sometime.
Awesome
12:05 I prefer to go with the path of least resistance and just compare it to certain weasel relatives that shed their fur for white during winter. Is it likely ? Absolutely not and I'm aware of that. Is it possible even if it's 0.01% chance ? I think so ? I mean some birds shed their feathers during winter in order to prepare for the breeding season in spring so it's not out of the realm of possibility in my eyes.
(Also about how feathery Nanuqsaurus is, some animals grow more fur (dunno about feathers in birds) in preparation to winter like Bison)
Need an accuracy review for life on our planet plz
I think Steve Irwin is more famous in Australia and America than the uk because I only heard of him when he died, don’t worry we still have a Steve, Steve backshall was our Steve Irwin.
☹️
Hey red raptor are did you study palaeontology or any related fields or is it more of a really pasionate hobby
I'm assuming it's a hobby.
It's a passionate hobby. My profession is actually Social Studies Education. I had to choose history or paleontology and in the end I just went with history
Yo I got a copy of that Steve Erwin book from when I was a kid
Life on Our Planet is not as bad as people say. I'm glad that Netflix did it. It has some problems, for example you will hate the word "dynasty" after watching it. But over all it's good. Not great, not amazing, but good. I'm happy that we got another paleo documentary
Well, putting ostioderms on rex and allo is kinda stupid and inaccurate
@@Corcovatuz I totally agree, allosaurus looks so bad, but on the other hand most animals look really good
Life on our planet is excellent
This means that you're a peanut brain
@@filippozauc, allosaurus looks excellent in life on our planet, way better than jfc
Mimicry isnt that uncommon. There are a few annimals that actualy use it. Tigers, seals, crows, baluga whales and ofcource parrots.
Also there defiantly some i missed.
So no comment on the speculative mimicry that enabled the Troodon to summon the Pachyrhinosaurs thinking it was a calf in danger?
Eh I discussed it before and then there was a lot going on in the climax so I forgot about it for a sec.
You need to do life on our planet next
Life on our planet review?
It`s so sad that they get rid of the name Troodon. I loved this dinosaur and hope that they would reestablish it when describing some new species of polar dromeosoroid if such would be found. I think it deserves a comeback
Nah, it doesn't, but i'm fine with "troodon" being a common name for members of the family
I don't see what's the issue with calling a troodontid a Troodon.
Is it wrong to call a lynx a cat because it's not Felis catus?
😆
yo life on our planet is amazing
The dino segment is a 4 out of 10, reused jw designs and way to many ostioderms.
it's not dinosaur documentary
Pachyrhinosaurs did not have feathers. It is all science fantasy not all dinosaurs have feathers.
Small mammals can get named after their teeth, but when Troodon does it they're the waste basket.
That doesn't seem fair at all.
Right?!
I forgot- did he say arctic troodontid? Or just Troodon?
Troodon
ah alright I forgot which one he said in the making of video tysm lol-
hey red,i wanted to ask a question for a long time. Is the gorgosaurus a dubious tyrannosaurid? Because I've been getting informed by many people that say that gorgosaurus was dubious and it was nanuqsaurs all along. But is this true?
No. A species from the Arctic is just a Nanuqsaurus, but Gorgosaurus libratus is still perfectly valid.
