Take a moment to think about the appearance of a modern bird - like a parrot, or something similar. We know these animals have relatively thick bodies, feathery coats, unique patterns, and varying colors. Now, think about a parrot’s skeleton. Based on the bones alone, these birds seem like they’d have long, slender frames - yet the layers of skin and feather coverings make them look quite different than their gaunt skeletal structures might suggest.
And this exact phenomenon presents a practical challenge when it comes to reconstructing accurate depictions of dinosaurs. The challenge of capturing the forgotten peculiarities of dinosaurs is at the center of “All Yesterdays,” a book written and illustrated in part by C.M. Koseman - whose work you know from his other most famous book “All Tomorrows.”
So, let’s take a look, and imagine what unique aspects of dinosaurs may not show up in the fossil record.

I love the idea of a group of researchers stumbling across a T-rex, but instead of rushing at them and trying to eat them it just kinda lazily looks at them and goes back to sleep. Or maybe a sauropod twisting in all sorts of weird ways trying to scratch an itch, like you see animals do today

[@dracodracarys2339]

If anything, it's herbivores you should be afraid of. Carnivores will not waste their energy and risk injury on a meal that's more trouble than it's worth. Herbivores will utterly pulp anything that enters their territory that can vaguely even be seen as a threat.

[@SineN0mine3]

Its probably a bit dated now since the cgi was the main selling point at the time, but the documentary "Walking with Dinosaurs" made an effort to try to depict dinos more like you would see animals in a nature film than monsters from a hollywood movie. The brand went on to do live shows with animatronics and puppets but the documentary was around a long time before that. It might be nostalgia, but I loved those docos when I saw them on TV.

[@Sergei_Ivanovich_Mosin]

​@@lekhaclam87 The worst example of the opposite of this in movies in Jurassic Park III when the team stumbles across a t-rex feeding off a several ton corpse, and for absolutely no reason what so ever the t-rex abandons the extremely large food source to chase a small group of human's who would be like a single bite to it. Like have you ever seen wolves just abandon a deer carcass to chase crows for hours?

Or even like lions, which -are- vicious if you're a prey or another predator that might be competition (hyena, for example), but also pretty lazy most of the time, and definitely don't just roam around slaughtering at will. It's why there's old stories of cape buffalo being one of the most dangerous animals in Africa, not the lion or leopard or anything. Hippos, too, rank -way- up there. It makes you wonder just how dangerous the herbivore dinosaurs -actually were- compared to the predators. I bet some of them were really quite aggressive, just like we see in some modern day large herbivores.

And by knowing the modern nature it is very likely they looked somekind of similar, because back then they inherit the niches modern animals ocupy now. Dinosaurs had millions of years to adapt. They are nor likely to be just simple reptiloids. It makes you think how normal those creatures really looked like for the modern human...

I am bound to propose a game where I give people pictures of skeletons of a Rooster, an Owl, a Turkey, An Ostrich and a peacock to show people how it is impossible to distinguish those animals from their skeletons even though they are so different.

[@tompotter8703]

Sort of the problem is that the skeleton can only tell us so much, and soft tissue like skin rarely fossilises. Lions and tigers are regarded as different animals even by toddlers due to their different colours and behaviours, but we’d never know for sure if we only knew from fossils, since their skeletons are so similar. The book also features a segment called “All todays” which satirises the trends of depicting dinosaurs as skin wrapped monsters, applying behaviours to them with little to no evidence or basing reconstructions of animals on distant relatives due to incomplete fossils (as seen with Spinosaurus and Deinocheirus, which turned out to be marginally different from their cousins) by applying all of these artistic tropes to modern animals, such as elephants as emaciated trunkless monsters, humming birds as blood sucking parasites, and snakes having legs and feathers.

The antelope which are a Tiger's primary prey are colour-blind & so find it difficult to discern between red & green pigments (possibly Deuteranopia), explaining the Tiger's apparently bizarre bright orange & white (with black stripes) fur colourings given it's environment filled with myriad hues of green. So, once you eliminate colour & compare the tonal values of their coat with that of the surrounding foliage of semi-tropical/tropical plants, a Tiger will vanish into the background in an astonishing exemplar combining both concealing & disruptive camoflage. Try to imaging all the parallel Predator/Prey Dynamics in Dinosaurs & you start to grasp just how challenging being a Paleoartist truly is. Typically the best that they can do is follow the science, with limited artistic license based on our understanding of modern animals.

[@LudosErgoSum]

@@FierceLord I think you should study a bit more how science works. Just because we can't directly experience the results of science with our own bodies and senses, does not invalidate experiements done with instruments and methods of science. The point of science is to create reproducable results. Scientific speculation, such as in this book, is there to fill in the gaps of knowledge we do not yet have access to with current data and methodology. Dinosaurs in particular have gone from slow, lumbering lizards to more active and agile avian-like creatures with the progression in paleontology. This transformation in appearance, would not be possible without science. Speculation then become the realm of both frontier and fantasy as scientists and artists can chalk up ideas that could later become testable as new specimens are found or new methodology become available to research those specimens.

[@TheAkwarium]

[@rga1605]

I thought the part on the Laellynasarus to be interesting because the artists were conflicted on portraying them as cute. This is something I noticed in a lot of speculative biology works, on how sometimes it feels like the artists are obligated to make creatures as "uncute" and "unpretty" as possible. You can make a point that evolution doesn't need to conform to human's beauty standards (like, a birrin could think human are ugly as frick: "haha, they have only two eyes and no wings, what a bunch of fugly losers, my grandma is prettier than them"), but that doesn't stop animals in real world from being colorful and, as the meme says, "shaped like a friend". So I think speculative biology should consider this when making new creatures, obviously when it might work.

The planet seams like a paradise, but they end up discovering a race of intelligent aliens living there and so much more.

To be honest, I just searched the skeleton of a rooster and I can totally see how I would imagine a Jurassic Park looking Dinossaur looking at just the skeleton, rather then imagining the top of the head (comb) , the big chest, the feathered tail...

[@petulantpeterturbo]

The depiction of a Tyrannosaur sleeping is very interesting to me, and I’d like to throw my hat in the ring. Given what we know of the creature right now, it doesn’t look like it even could get up from a sideways position without help unless it’s tail or neck was incredibly strong, even then getting up would be awkward. What if Tyrannosaurs laid down on their stomachs to sleep, with their legs folded up like a cats or modern bird’s? That way they’d likely be most comfortable, as well as being able to just use their legs to stand, with both their tails and necks available to help if they need it.

[@zalybrainlessgenius503]

This is my new most favourite speculative zoology channel ❤️

[@Kosmid]

I just got done bingeing a bunch of your videos! Great work!

[@katherinepollard3920]

Same!

[@ErickeTR]

A really informative video. One can clearly see that the person who made this video put a lot of effort into it and has some degree of passion for the subject. Thanks for spreading the beauty of nowaday's paleontology!

[@valmarsiglia]

05:51 - "The thick layer of feathers certainly makes the animal look less frightening...." Uh, no it doesn't.

[@kujaneck]

Amazing! I always criticized artists making dinosours look too skeletal.

[@UGNAvalon]

Now I’m imagining a Dilophosaurus baby playing “hide & seek”/“peekaboo” with its frill, except instead of eating its playmate, it wanders away to take a nap with its mom.

[@baxel54230]

This channel is so high quality ! Great research, interesting subjects, professional voiceover and editing : congrats !

[@lluuvbug2465]

This has become one of my favourite channels.

[@robinchesterfield42]

As for adorable, floofy dinosaurs--have you seen some pictures of the Sinosauropteryx? I would TOTALLY buy a plushie of that thing. FLUFFY RED LEMUR DINOSAUR. XD

[@alfa_kenny_body]

Good to know paleontology science evolves! Like most six year olds obsessed with Dinos, some depictions i.e. Pachycephalosaurus, always confused me. Great content as always

[@IthliniEllyanSenah]

I discovered this channel 2 days ago. I watched everything and was sad that there is nothing new. Then this!!

[@grimtilland6776]

I absolutely love your channel! Keep up the good and weird work!

[@jennifermason8310]

Carnotaurus be like, gib hug

[@KerbalFacile]

I rewatched "Jurassic Park" recently, it was really striking how off the mark the representations of dinosaurs were back then. Their "velociraptors" should have instead looked like cassowaries, IMO.

[@Captianmex1C0]

Well the Dinosaurs In Jurrasic park look Unrealistic on purpose, They do that because people find Shrinkwraped Therapods "Cooler" than the chunky slow Humming Hunters that they actually were. Just for example the Raptors In Jurrasic park 3 were explained in an official Jurrasic world website to be a failed "Feathered" dinosaur project by Dr Wu, And the Spinosaur was the first Advanced Genetic Hybrid, Aka the First Attempt to create an indominus rex

[@pheonixfire9517]

Actually veloceraptors, were about 3ft tall. So more like...angry pheasants. Lol

[@hungchoonghow5857]

Yup. I saw a cassowary in a local zoo some years ago and my immediate thought was : velociraptor.

[@omarjaved9748]

@@hungchoonghow5857 weird, shouldn’t your immediate thought have been: cassowary!

[@domesticus2958]

I want to note that the general appearance and aesthetic of the dinosaurs in Jurassic Park isn't that unrealistic by modern standards. Yes some of the dinosaurs like the Velociraptors (actually Deinonychus) haven't aged well, but things like the Brachiosaurus and T. rex aren't that off the mark. The levels of fat and muscle are pretty congruent with what we think the animals had nowadays, and the conservative shades of red, brown and grey are not unreasonable for large reptiles. The idea of depicting dinosaurs as thicker and more vibrantly colored than how we often depict them is a great thought experiment, but sometimes the pendulum swings too far in the opposite direction and we can end up with something just as unrealistic.

[@nono9543]

Good to see CS Koseman finally get the recognition he deserves

[@Irmavep666]

Been watching this all afternoon. Subscribed, really enjoying this channel so far.

[@eternalmiasma5586]

“You can see the feathers make it less scary” that thing looks death incarnate

[@Stothehighest]

Someone, XKCD I think, made a venn diagram stating: People who think dinosaurs with feathers aren't scary / People who've never been attacked by an ostrich.

[@MouldMadeMind]

@@Stothehighest why osterich? Aren't geese deadly enought?

[@zenebean]

The elasmosaurs remind me of giant grass eels, it's such a surreal picture. The therizinosaurus is my favorite though, I love the giant shaggy look like giant sloths

[@KARIMYHATARAA]

Biology, especially speculative biology, will always be one of my favorite interests

[@Isai314]

This channel has content similar to huge channels. I love it, keep up the good work.

[@dontworryyoullbealright6949]

7:34 maybe its tail is used as a bait or a distraction from predators

[@_sto2972]

For some reason I find cute a T. Rex slepping on it's side

[@Trishula]

This channel is EXPLODING and I’m v happy abt it

[@lukeyager5039]

Dude, these videos are so good honestly. I know you're gonna do a video about all tomorrow's next AND I CANNOT F@%$!ING WAIT!!!!!!

[@killerqueenbiteszadusto1771]

I like dinosaurs being seen as animals, like playing and all that makes it seem more ‘realistic’

[@oneonetwothreefiveeight]

I had this dream recently that a friend of mine had a ton of chickens, and one of them was kind of hidden and it slowly revealed itself and it was like the size of a horse. I was like what type of chicken is that ? how is it supposed to reproduce with the other chickens ? We were laughing about it but in retrospect it was pretty horrifying

[@MidnightDarkness666]

Just wanna say, the parrot footage you showed at the beginning is super cute! Lovely little birdies!

[@timlopez643]

The plesiosaur neck competition was absolutely mind boggling because it was 100% believable...

[@trstmeimadctr]

I think that paleontologists should make a habit of pairing conservative as well as deeply speculative versions of reconstructions together when presenting things towards the general public and perhaps even towards each other because each one really can be considered equally plausible to some degree.

[@JMObyx]

Imagine you're a protagonist on some time traveller show and you don't know it yet, however during your walk in the strange forest you all of a sudden encounter these strange tall feathery creatures that sort of resemble penguins in body shape, but all loom together, tall and silent like a feathery forest within the forest of bigger trees. They waddle along like a flock of penguins would, but slowly, more assuredly, and they waddle past you, towering over you and stunning you with their mystique as they hold their massive claws at their side and waddle silently. They look at you, inquisitive as they pass by, some stop for a few moments to sniff, not knowing what you are. And then you recognize the creature you just had an encounter with when one of them reaches its claws up to devour leaves. Therizinosaurus.

[@Salvador-312]

8:35 I love this picture, it gives off some Evangelion vibes

[@tinobemellow]

Between this, All Tomorrows and All Todays, C.M Koseman managed to make humans and modern animals into the scary monsters and dinosaurs into the normal, wholesome animals.

[@florenmage]

7:08 I want one. I will keep him in a comfortable doggie bed and feed him treats. He will get regular pets and walkies. I will call him mr floofy feathers the magnificent. He will be my little buddy buddy. Sho Cute UwU ^_^

oh my god you put the subtitles in portuguese!! Thank you very much for your attention and for placing my order!!

[@Lillian2167]

I need to get this book, such lovely paleo art and amazing ideas of how dinosaurs may have looked and lived! :3

[@mathieuleader8601]

the elasmosarus's necks looks like the parasitic pinworms

[@GlassesnMouthplates]

It makes me wonder if the reason why dinosaurs were commonly drawn to be these terrifying giant predatory lizards is that the human mind is naturally too receptive to see horror elements in skeletons of animals. For ages, we have been using skeletons as the imagery of death and inhuman entities so naturally anyone who sees a dinosaur skeleton for the first time will speculate that we're looking at a creature that would tear us to shreds and devour us in one bite in its past life.

[@tephlin1405]

10:19 that dog winked at me like it's in a commercial

[@NeroLobo]

This is great video. Thank you.

[@robertpowell9982]

When you remember that dinosaurs are ancestors of birds, you then look at real world bird-like behaviours such as the bizarre courtships of various species of Birds of Paradise, Western Grebes and Prairie Chickens as well as various soft tissues found on various species like Condors and Frigatebirds, it really makes you wonder what we aren't seeing from the fossil record. As well as the limitless possibilities of species that never even got preserved. With tiny sparrow-sized dinosaurs found in amber fossils it even opens up even further possibilities of tiny 'songbird' dinosaurs contrary to the titans we associate with dinosaurs.

I've seen the picture of sauropod, covered in black and white stripes like a zebra and this really shows how unexpected such interpretations can be
