Dead Sound's "Dinosauria: Our Frozen Past" | Accuracy Review

[@terrythepterodactyl8048]

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.

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.

[@jamesheasley2980]

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.

[@seanmckelvey6618]

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.

[@JurassicReptile]

⁠​⁠@@BermudaHawk47it’s not like tigers are scaly while leopards have fur. It’s not exactly the best comparison

[@BermudaHawk47]

@@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.

[@seanmckelvey6618]

@@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.

[@imbored3416]

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.

@@rhyusbrand8311 I love dinos I woud hate making that mistake

[@apnosaurus]

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.

[@BermudaHawk47]

Yea fr, just take a look at the difference between lions and snow leopards who are literally in the same genus

[@DreadEnder]

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)

[@maxtube444]

some people shorten it to “php”, if that helps

[@filippozauc]

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

[@Mega_Raptor]

I would love to see a Review on When Dinosaurs Ruled (2000) with Jeff Goldblum

[@creakingskull7008]

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

[@prasetyodwikuncorojati2434]

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

[@evananouna8244]

As far as the feather point think about elephants and mammoths, one is very hairy and the other isn’t

[@PackHunter117]

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

[@michaeldeak5727]

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.

[@tobiasedwards2643]

Since Troodon is a wastebasket then should we even be calling the group Troodontids?

[@Bagelgeuse]

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.

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.

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)

[@yeahminecraft1627]

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.

No. A species from the Arctic is just a Nanuqsaurus, but Gorgosaurus libratus is still perfectly valid.
