Damn, sorry I didn't respond for a few days but Sherdog was pulling it's migration bullshit so I couldn't reply back when I wanted to.
Don't worry, i'm aware of that!
That's actually I term I haven't heard of before. So thanks for teaching something I didn't know about. I'll have look more into the concept of the Square-cube law sometime.
I can explain it right here, it's actually super simple - but in my case it has really opened my eyes to a lot of things!
Imagine the following cube:
edge-lengths: 1m/1m/1m
volume: 1m³
weight: 1t
surface area (bottom): 1sqm
weight-loading on the bottom surface area/weight-distribution: 1t/sqm
So far so good, now let's imagine a cube which is twice as tall (and wide, thick, etc.).
edge-lengths: 2m/2m/2m
volume: 8m³
weight: 8t
surface area (bottom): 4sqm
weight-loading on the bottom surface area/weight-distribution: 2t/sqm
Conclusion: while the second cube has four times the surface area (and thus also a bottom area 4 times as big), the weight of the second sube is 8 (!) times that of the first cube, thus it has a higher weight-loading per squaremeter.
For this reason, cats (and other small animals) can fall from very high without hurting themselves, while an elephant would break its legs from 1m of falling height or so.
This so called "square cube law" is also the reason why smaller powerlifters can be stronger in relation to their bodyweight than bigger powerlifters.
It's the same reason why some bugs and ants can lift up to 1000 times+ their bodyweight.
It's also the reason why the babies of cold blooded animals are (way) smaller in comparison to their adult size and also why they can afford to already have the same proportions as hatchlings. (E.g. crocodiles).
Mammals on the other hand, always need to sustain a certain temperature to survive, and since the ratio of volume to surface area gets worse in terms of keeping warmth the smaller a body gets, mammalian babies are:
a) rather big as babies, compared to their cold blooded counterparts,
b) in their proportions closer to a ball (short limbs, rounder, thicker bodies) as a ball has the least surface area of all geometrical bodies, enabling it to hold warmth the easiest.
Maybe we will find a Tyrannosaurus or some other large Dinosaur in amber. Although there has been some controversy surrounding that lately. In fact Ben G Thomas made a pretty good video about that you should definitely check out.
Haha, have just watched this video recently and yes, it's quite interesting!
I think you'll enjoy Ben's videos a lot. He and his brother Doug have a lot of passion for and knowledge about Dinosaurs and Paleontology in general. You should also check out Henry the PaleoGuy (the guy who made the video this thread is about) TREY the Explainer, and E.D.G.E. They are pretty good too.
So many good channels about (pretty much) anything on Youtube. Hopefully i'll manage to delve into all of these.
For sure, it's bad enough that ancient humans had to deal with short-faced bears, saber-toothed cats, dire wolves, cave hyenas, and cave lions. Throw in some Tyrannosaurs, Allosaurs, Spinosaurs, Carcharodontosaurs, and raptors into the mix and mankind would have been fucked.
Yeah i agree. Especially "smaller" Theropods like Allosaurus and all these raptors would've been a bane for humans.
I think one is quite safe from a tyrannosaurus if one lives where there's lots of mountains near. I think a Tyrannosaurus chasing prey upon a steep mountain would lead to it falling and eventually dying, as it's so big and heavy.
The raptors though...
I wish I could go back in time and keep one of those bird ancestors as a pet. But chances are that would fuck up the timeline it wouldn't be worth it.
Hmm... as far as i know, what we call time doesn't work that way either, but i know what you mean and i agree, would be epic. Would be generally fantastic to see the world of back then...
On the other hand, the fact that we never saw prehistoric dinosaurs, is part of what makes them so magic.
I haven't eaten crocodiles either, but I've heard that too. So maybe Dinosaurs tasted similar to crocodiles.
Yeah, it seems to be the consensus.
Yes I have heard of Liopleurodon. Although it wasn't the 150 ton behemoth that is shown to be in Walking with Dinosaurs, it was still pretty large (about the size of an orca or a large great white shark) and it must have been a very fearsome predator during it's day.
Absolutely! I wonder how intelligent it was. Intelligence makes a big difference in (these) animals. Great white's don't avoid Orca's for fun.
And no Liopleurodon wasn't a Dinosaur. Liopleurodon was a species of marine reptile that belonged to a now extinct family of reptiles known as Plesiosaurs. Marine reptiles used to be very common during the Mesozoic (the time of the Dinosaurs) but now sea turtles, sea snakes, marine iguanas, and crocodilians are the only aquatic reptiles that are around today unfortunately.
Ahh, yeah, i wasn't entirely sure, but yup. If only some of the plesiosaurians could've survived...
Walking with Dinosaurs is a good show. Although it has some outdated information in it (because it was made almost 21 years ago) it's still a solid documentary and the CGI mixed with the animatronics still hold up pretty well in my opinion. I like that the makers of WWD treated the Dinosaurs and the other animals featured in the documentary as living, breathing, animals that once lived on this planet and not as generic movie monsters.
I love it! it was a gigantic part of my childhood and i agree 100% with all you've just said. Especially the latter part on why it stood out, with the dinosaurs being treated in a less "action movie-like" way.
As many guys post in YT comment sections regarding WWD, they should just redo that documentary with up to date information etc. Would be mental!
If you haven't already, you should check out the Walking with Dinosaurs spin-offs such as Walking with Beasts, Walking with Monsters, and Walking with Cavemen. Also check out Chased by Dinosaurs, Chased by Sea Monsters, and the Walking with Dinosaurs special "The Ballad of Big Al". Those are all well made and entertaining documentaries as well.
Yes Mosasaurus was badass, although it wasn't a Dinosaur either. Mosasaurus was a species of aquatic lizard.
I've seen walking with beasts as well, reeeally enjoyed it also. One of my favourite animals from there is the Basilosaurus, but i also remember these gigantic and savage boars, as well as the Indricotherium (which is named differently nowadays, IIRC) and some others.
Don't know for sure which of the others i have seen and which not.
