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.

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.

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.

I'll be honest: until now I never realised how "normal" dinosaurs could look like, yet on the other side, remembering the hippopotamus skull interpretation gave me the creeps a few years ago. Who would interpret such a chubby creature with a demonic shape? ...Well exactly the same point is here made. We do not know how dionsaurs really looked like. 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...

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.

Always drawn with no fur or feathers, all muddy greens and browns. But that's not what animals look like! How could you know a chameleon can change it's colors just looking at it's bones? How would you know that a peacock has such large impractical feathers? Or that male lions have beautiful manes? Could you tell how friendly a dog is, just by looking at it's sharp teeth? How would you know that glass frogs have clear skin? You wouldn't. So why assume when you can wonder?

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.

@@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.

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 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.

by the way there is actually a mummified dinosaur, you get to see the actual dinosaur skin ON the dinosaur and its real, so well preserved that it looks almost like a statue. its a tiny bit cracked here and there but its amazing, its the type of dinosaur that has an armored back. there are a few other mummified dinosaurs but not as good as this armored one edit: i think its called a nodosaur

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 2 жыл бұрын

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

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.

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.
