This is a serious issue with our perception of dinosaurs though. So many animals that look completely different to one another nowadays have quite similar skeletons. You really can't be too sure about fat distribution, muscles, cartilage, skin features, colours, textures in fossils.

Dinosaurs are traditionally represented in drab colours, with skin placed upon the skeleton with a process known as "shrink wrapping", tightly attaching the skin to the frame. But many animals that we know now really don't work like that.

Anyone who’s interested in this should check out the book All Yesterdays, where artists have tried reimagining dinosaurs with actual muscle and fat instead of the shrink-wrapped look. They updated some classic dinosaur designs based on recent findings, such as how triceratops may have had spines/quills along its back like a porcupine.

To demonstrate how unrealistic the shrink-wrapping style is, for the second half of the book they applied that technique to known modern animals with some terrifying results, like these swans.

Don’t forget All Tomorrows

Yeah, the way a brachiosaurus' skull is shaped, it's possible it had a trunk but that wouldn't have fossilized since it's all muscle and skin.

Would a dinosaur having a truck result in different bone structure?

[–] CitizenKong 11 points 1 year ago

Well, if the animal drives everywhere instead of walking, we might see a deformation of the hips.

Never knew it was called shrink wrapping! TIL

Reminder that penguins, along with all other birds, are technically dinosaurs

[–] hglman 22 points 1 year ago (1 children)

Don't really need to say technically, they just are dinosaurs.

[–] [email protected] 3 points 1 year ago

Well yes, but I said "technically" because the technical scientific definition of dinosaur is not the one most people think of.

[–] [email protected] 4 points 1 year ago

And it's not just technically: birds literally are theropod dinosaurs, and the only known dinosaurs to survive to modern age

Future archeologists are gonna assume I was skinny 🙌

Yes please! 🥹

[–] toxicbubble 5 points 1 year ago

not a bad theory, but I assume penguins evolved their shape for swimming and insulation

[–] [email protected] 4 points 1 year ago (1 children)

Eh, not likely, especially for dinosaurs that we have full skeletons of, because that much fat would be seen on the bones as damage from walking.

[–] [email protected] 2 points 1 year ago

Who said it's fat, though? Sauropods are interesting in that they had systems of air sacs, like modern birds, that can puff up their apparent size without necessarily adding a lot of weight.

wait so if a penguin commits war crimes how do you hang them

[–] [email protected] 1 points 1 year ago

His neck is so thick, I feel like he's just gonna swang and dangle around for a really long time

[–] dreadedsemi 2 points 1 year ago

So penguins are wearing neck turtle. Or we should call the latter neck penguin.

land before time was my fav movie as a child. Tree star rolled up for transport, "little foot" in mothers voice, damn, it's really imbedded in my brain lol.
