Why are people so mad at the whole feathers thing anyways? How is a giant chicken any less intimidating than a dinosaur?

Because birds are dumb and feathered poop machines.
>>
>>2409513
a better question is why does everyone think "chicken" when they hear "feathers" despite the wide variety of extant birds. if that isn't stupid enough they think of the fat domesticated chicken rather than a wild specimen

Fact: Some species of dinosaurs had feathers. We have the fossil imprints of said feathers as proof.

Another Fact: Other species of dinosaurs did not have feathers. We have fossil imprints of skin/scales as proof.

>Let's have a debate on weather dinosaurs were feathered or not
If you want to make this thread, don't start off on such an idiotically sweeping statement. Some genuses sported feathers and others didn't--there is no discussion to be had about whether dinosaurs as a whole had feathers, but which clades had feathers.

In short, fuck off you moron.

Do you see any feathers?

I appreciate your joke.

Some were some weren't.
Velociraptors, or at least some of them did, there were bone ridges and bumps similar to ones found on birds of today to indicate feathers would appear.

But really you made this thread to talk about the T Rex didn't you?

As far as T Rex goes this one really can go either way.
The skin patches recently found only showed scales, but feathers don't have to appear all over the body to prove feathers were present, ostritches or most any bird from ratite family for example might have scales on legs but feathers on most of the body.

This means that if the skin patches found were on the legs or any part of the body that doesn't have feathers, it doesn't necessarily mean there weren't feathers at all, just none on the patch they found.

On a side note just finding scales doesn't disprove feathers.
It's definitely possible for feathers to be mixed into scales, see juravenator and anchiornis

>It may have been feathered, but not like this.
So far, all of its skin impressions are scaly. Meaning factually it was scaly.

But there is evidence to believe it may have had feathers. in at least some way.


This new feathered rex is badass, but overly feathered.

Something like that would overheat.

>>2409765
I'm thinking more along the lines of this.

As in more of a feathery ridge from its head and back. Kind of like an Asian elephant with hair.

>Dinosaur origins are more unique compared to other reptiles
Some of the most primitive dinosaur species (e.g kulindadromeus) and the closest archosaur relative to all dinosaurs (i.e. pterosaurs) show signs of being at least partly fuzzy. Even longisquama an (ancestral reptile related to what evolved into them) was partially FEATHERED
https://www.youtube.com/watch?v=sGAixpQcqdU


Meaning primitive feathering was already long established to be part of their biology. Thus all dinosaurs may be feathered, even if at the bare minimal as seen with hair on humans and African elephants.


So all dinosaurs were likely scaly and feathery.
The question now is, what was the ratio of scales and feathers?
>>
>>2410034
Pseudoscience.

Dinosauria is a separate group all together. At most some ceratopsians had quills.
>>
>>2410034
>The question now is, what was the ratio of scales and feathers?

by species we're at about 99:1 scaled.

using bracketing we're closer to 95:5 scaled.

It's pretty much the main reason why we humans still have unnecessary hair covering our bodies. Or at the very least, covering many parts, like the our arms, legs, chests (esp if male) and upper back (esp if male). Even human women have very thin fuzzlike hairs on the sides of their faces (almost invisible, until you really look in)


This is because we humans evolved from hairy apes, which evolved from hairy monkeys to which evolved from a hairy mammal.

>>2410093
>hair
>unnecessary
its a heat sink and dry lubrication to the pivot joints (pelvis/collarbone)
head hair to keep our brain cool when our head ratio to body as children is huge, when we get older is becomes debatable
>>
>>2409489
neither of those pictures are right. the one on the left has the wrong lips, teeth were all covered. trex had a little down, mostly only when young. also only in certain spots along the back. definitely nowhere near that amount of feathers
>>
>>2410093
>This is because we humans evolved from hairy apes, which evolved from hairy monkeys to which evolved from a hairy mammal.
Nope. We had a common ancestor with those critters, we aren't descended from them.
As for hair, can you think of a better ararm system for insects etc crawling on our skin?
They might be small enough for us not to notice their footsteps but if they hit a hair we're on to them.
Successful parasites (fleas etc) are usually built on a vertical profile because of this.
