Dinosaurs are not 'birds' but they are the ancestors to birds.

If you're asking 'did T. Rex' have feathers then almost certainly yes.

Not really, it's just retarded when autists bring it up when it isn't needed because they can't handle that people use the term dinosaur to not include birds, even though that is technically incorrect. I brought it up because someone specifically asked about it, which is reasonable.
>>
>>2301091
A tyrannosaurus is not a species of bird, actually. It's a species of dinosaur.

It's closest living relative is a bird, but it is not a bird.

Our closest living relative is a chimpanzee, but we are not pans troglodyte- and we both evolved from a gibbon like creature.

Dinosaurs are not birds.

We nitpicking now

extant (living) birds are quite different from extinct dinosaurs in many ways, so it's not safe to assume that all dinosaurs are the same. For that matter, extant birds are quite different from Jurassic and Cretaceous birds. Time passes, the environment changes... life evolves. Extant birds have been separated evolutionarily from the other coelurosaurian dinosaurs for some 150 million years, so they do look, act, and function quite differently, but science has shown us that they are closely linked by their common evolutionary history.

They're linked by evolutionary history. We evolved from all multi-cellular organisms, but that doesn't make US multi cellular organisms.

Birds may have evolved from dinosaurs, but that doesn't make them dinosaurs.

No.

Dinosaurs are not birds and you're grasping at straws.

Evolution is one animal changing to become a new one. They are NOT the same animal.

We actually have a very good idea how the trex looked. The Sue specimen gave us skin imprints which showed that it had a pebbly skin texture, and no feathers. It also had the imprints where the muscles attached, so we know roughly what the musculature was like. We also know that it was most likely a warm blooded creature, keeping it pretty mobile and capable of running fast enough to hunt down it's prey. Put all these together and it's general size of about 7tons plus the climate of it's time means it more than likely did not have feathers. Maybe it's young did, and maybe it had small crest feathers, but it was not fully feathered as an adult, and no science fact has proven otherwise.
>>
>>2301905
No one is saying it was fully feathered. Most of the feathered reconstructions are half naked.
>>
>>2301905
Actually i believe it was less than 7 tons (it might be true,i don't have wikipedia to back me up,after all) since it was discovered that it's bones were hollow inside,just like a bird's bones,which dropped it's "estimated" weight significantly,possibly to around 4 tons? It could be that it's estimated weight with full bones was 10 tons and then it was dropped to 7 tons after the discovery,though.

These guys have so far done the best work for a popular artistic restoration of T. rex, and gathered it all in one picture, for your viewing pleasure.
>>
Tyrannosaurus rex is a species of Tyrannosaurid, Coelurosauran, Tetanuran, Theropod, Saurischian dinosaur. Birds share all of those classifications except Tyrannosauridae.

And by that logic, modern birds would be Avialan, Paravian, Pennaraptoran, Maniraptoran, Coelurosauran, Tetanuran, Theropod, Saurischian dinosaurs.

Most of us agree that birds are dinosaurs.
But are birds fish? Is a latest common ancestor of birds and latimeria a fish?
>>
>>2304448
Fish is a paraphyletic term which is useless in taxonomy. It includes every non tetrapod vertebrate and is akin to 'invertebrate'. In this sense, birds are not fishes. The term that includes bony fish and tetrapods, but not cartilaginous fishes is called Teleostomi.
>>
>>2304464
"fish" is only paraphyletic because it excludes tetrapods.

so if you define it to include them it's fine.

The only reason it's not used to name a clade including trout and humans is that it's not a latinized name. Neither is "bird." So the same objection applies to both names.

so if we treat them equally, birds are indeed a type of fish. Which is to say, Aves belongs in clade Osteichthyes.
>>
>>2304464
>Teleostomi.
also of course "Teleostomi" is polyphyletic and hasn't been considered a clade for over 3 years now.
>>
>>2304472
Well, of course you can do that, and is a valid reasoning, but I don't like the idea. First, fish would be synonymous with teleostome, and it would include animals that traditionally aren't classified as fishes.
It's like making the term 'invertebrate' monophyletic, it would be synonymous with animal, and it would lead to vertebrates being invertebrates, which of course, makes no sense.
Personally, I'm comfortable with paraphyletic terms, as long as they aren't used with scientific rigor.
>>
>>2304474
You're totally right. With 'Teleostomi' I meant a clade with Actinopterygii + Sarcopterygii. Apparently this clade is called Euteleostomi, which differs from Teleostomi by not including the extinct acanthodians, which are themselves stem chondrichthyans.
Oh well, Euteleostomi is what I meant. Thanks for the correction, anon.
>>
>>2304484
we're seeing this whether we like it or not. Obvious example is "Reptilia." I think currently clade Reptilia includes Aves, so we're left with interesting circumlocutions such as, "Birds are reptilians but not reptiles."

I suspect either the paraphyletic common name will become synonymous with its equivalent clade or the common name will fall from use.

I further predict that this will happen 150 years from now, because that's about how long it takes the American public to ratify new evolutionary science.

>You are not a fish you vapid cunt.
Actually all tetrapods are still fish just VERY MUTATED lobe finned fish.

>Why the fuck would a several ton warm blooded animal in a subtropical environment need to be covered in feathers?
Scientist arent too sure why the fuck some synapsids went HEY DUDE LET LOSE THIS ARMORED SCALY SKIN FOR SOFT FURRY SHIT, evolution is just random mutations that are filtered by the environment.

Oh yes thank for reminding me fur cause mammals to be parasite havens as well.
>Hurr it was to keep them warm
A clusterfuck of shit survived the Permian volcanic winter though WITHOUT MUTATING FUR.

Why did birds lose their teeth? They could ingest food easier with teeth.
>>
>>2308437
If the changes are more recent I'm pretty sure it's due to comparative genomics.

>armored
Scales don't mean an animal was even remotely armored. Scaled animals also get tons of parasites and shit too.

>>2308617
Flight. Makes them weigh less, and birds do just fine without teeth.

Teeth are only absolutely necessary for herbivores to chew and digest plants better. Carnivorous use their teeth to tear big pieces of meat and swallow without chewing, but if the prey is small enough for them they swallow it whole. See fish, birds, reptiles, etc.

>>2308720
most herbivores don't chew.

most vertebrate carnivores have teeth they don't use for slicing or chewing. See fish, birds, reptiles, etc.

>>2308638
Most Pterosaurs were larger than the average bird and had teeth as well.

Reptile is a very general terms. Crocodiles are reptiles and come from the same period, but aren't dinosaurs.
>>
>>2308851
Reptiles and dinosaurs are completely different species. Two major differences is that reptiles are cold blooded and their legs come from the side of their body instead of straight down.
>>
>>2308863
Reptile is just a meme word. Dinosaurs can also be reptiles, and synapsids too. It just means that they aren't covered by fur or feathers, and may include scales and terrestrial eggs.

But that's where you're wrong kiddo.

>Using proper terminology, birds are avian dinosaurs; other dinosaurs are non-avian dinosaurs, and (strange as it may sound) birds are technically considered reptiles. Overly technical? Just semantics? Perhaps, but still good science.

Daily reminder chickens are direct descendants of theropods and trex most probably had feathers unlike popular represenrations in media like jurassic park, the scaly reptoid dinosaurs is a XIX century archaelogic meme
