Categorizing dinosaurs as birds is pointless, anyway. Categorizing birds as extant dinosaurs… now that is much cooler.

I prefer my birds to be fish.

Do you secrete milk from mammary glands?
Bc that’s like legit the only requirement. We set the bar low. Not like those avians.
prole@lemmy.blahaj.zone 5 months ago
I was always taught live birth was also one of the requirements. Are there any other exceptions besides platypus?
WhiskyTangoFoxtrot@lemmy.world 5 months ago
Well, you have to be descended from a particular branch of the evolutionary tree that has the ability to secrete milk from mammary glands. If, say, a mollusc independently evolved milk production that wouldn’t make it a mammal.
JasonDJ@lemmy.zip 5 months ago
They wouldn’t independently evolve mammary glands, because only mammals have mammary glands, and they are not mammals, but mollusca.
I’d say that’s a bit of a chicken/egg situation, but I don’t think we need to bring in more classes.

Aww, poor soyjak, are you upset nature doesn’t adhere to your imaginary grouping made up before you had as much knowledge?

Is there anyone arguing against dinosaurs being birds anymore? This was still a relatively new thought to the general public when Jurassic Park came out, but IIRC, it was pretty well accepted among paleontologists even back then. More people try to badly argue that Pluto is a planet than try to say dinosaurs aren’t birds.

I know of such a man. Makes a convincing argument too, that I’ll be wholly unable to properly articulate, but my dumbed down understanding is that (in addition to other things) the “feathers” could be decomposed collagenous fibers from the skin of dinosaurs rather than true feathers, and we’re not actually sure even though feathers are the pushed theory. And he also doesn’t believe in flight evolving ground up, but rather trees down, basically not from creatures jumping away from predators but from them gliding away to another tree. His theory being that one actually works well to get you away from predators while the other would be less likely to be successful and more likely to get eaten before passing on the genes. Also something about the Yi qi.
Idk if he’s right, but tbf idk if the other people are either, who knows.

This is the other way around. There are some who want to push back the definition of “bird” to include more dinosaurs via earlier divergence. There are even a few that argue that certain conventially non-avian dinosaurs are actually from the agreed bird lineage but converged back on a bipedal dinosaur shape.

You do see it sometimes, where people complain that dinosaurs are no longer fearsome giant lizards because we found out that they might have feathers, on social media and places.
It generally becomes obvious that they have never met a goose, chicken, or been at risk of swooping before.

Is it not the other way around? Birds are dinosaurs, but not all dinosaurs are birds.

I believe that, nowadays, it is generally accepted that dinosaurs, crocodilians and birds are all “archosaurs”.
Palerider@feddit.uk 5 months ago
All the remaining dinosaurs are birds though…

Let’s compromise and call them both fish.
