Should birds be considered dinosaurs?

[I spent the winter writing songs about getting better]

Most paleontologists today actually seem to think so. This means of course that dinosaurs DID in fact co-exist with humans, and still do today.

yes (not anti-science)

[MasterJedi]

No, just because they evolved from dinosaurs in the ancient past doesn't mean that they're dinosaurs now. Just like humans aren't considered Apes.

[Amenhotep Bakari-Sellers]

Humans are primates and the mutation in the junior chimp causes dwarfism as per Darwin.

Birds are warm blooded reptiles that lay eggs.

Crocks, Gators and Birds are dinosaurs

No, just because they evolved from dinosaurs in the ancient past doesn't mean that they're dinosaurs now. Just like humans aren't considered Apes.

But humans ARE considered Apes (along with bonobos, chimpanzees, gorillas, and orangutans).

[Ban my account ffs!]

No.  Just like Lucy Lost Her Grip wasn't a human.  Birds devoloped alongside dinosaurs and continued evolving as the dinosaurs died.

Good point.  But then we should call birds saurischian like we already do, since birds are only descended from that branch of the dinosaurs.  In the way humans are primates.

So ill change my mind.  They are dinosaurs...but only after being saurischian birds, but before being called reptiles.  Nobody wants to really call this a reptilian dinosaur:

Calling people "apes" is generally frowned upon outside of certain subcultures.

It's the scientific categorization.

Dinosaurs can be used two ways in scientific descriptions. The most precise use would be to describe all creatures that share the same common ancestor as Triceratops and Tyrannosaurus (specifically their last common ancestor). That use includes birds. It does not include crocodiles or the more distant reptiles such as lizards and snakes.

Because birds are still extant and have a historical definition that predates dinosaurs, the term dinosaur is sometimes used to describe all creatures with the same common ancestor as Triceratops and Tyrannosaurus except birds. This can make for a clearer description to a lay reader, but it doesn't describe a scientific grouping in biology, ie a clade.

Since birds share a common ancestor with all other dinosaurs, and that ancestor is not an ancestor of other reptiles, birds should be considered dinosaurs in the scientific sense.

Yes, they are Avian Dinosaurs. If one wants to describe dinosaurs without including our feathered friends, they should use the term "non-avian dinosaur"

There are two major divisons of dinosaurs, the bird-hipped clade (Ornithischians) and the lizard-hipped clade (Saurischea). in retrospect the names are bad, because Birds are more closely related to the latter group than the supposedly Bird hipped bunch. The Saurischea are further divided into Sauropodomorpha (stuff like Diplodocus and other long necked dinosaurs) and Therapods. This last group splits further into a few classes until we get to the Birds. In fact, one of the birds closest relatives is, of all things, the Tyranosaur group.

Sharks, Gators, Crocks and Birds who evolved from Tyradactol are dinosar

[🦀🎂🦀🎂]

Actually Crocodiles and Alligators, although the closest living relative of dinosaurs (including birds) are not actually dinosaurs. They belong to a clade called Archnosaur, which includes the dinosaurs and the pterosaurs.

Sharks are not dinosaurs but cartiliginous fish. They branch off at a far earlier point.

[I spent the winter writing songs about getting better]

Sharks were actually around BEFORE dinosaurs.

[wolfsblood07]

So there were bird-hipped dinosaurs, and there were lizard-hipped dinosaurs.  Birds as we know them descended from... lizard-hipped dinosaurs. 
To me, they are not.  They are similar.  Especially birds like roadrunners.  But alligators and crocodiles are even closer.

Tyradactol = Safe dinosar

No, just because they evolved from dinosaurs in the ancient past doesn't mean that they're dinosaurs now. Just like humans aren't considered Apes monkeys.

right

[Senator-elect Spark]

Of course.

This.
