Reminder that penguins, along with all other birds, are technically dinosaurs
And it's not just technically: birds literally are theropod dinosaurs, and the only known dinosaurs to survive to modern age
Shrink wrapping ancient animals is a trip Here's a baboon! How horrifying lol

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.
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.
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.
