How did we switched from "Dinosaur are giant lizards" to "Dinosaur are giant birds"

Ziggurat@sh.itjust.works to No Stupid Questions@lemmy.world – 130 points –

When I was a kid, I learned about Dinosaur being "giant lizard", and it's been may-be 10 years, that I hear "Birds are dinosaurs".

I am curious on how the concept evolve, both among paleontologists, and among the general public.

*over 100s of Millions, but what's an extra zero amongst Internet friends

Ugh, life took ages to get started. Lazy bacteria!

It's still a hell of a long time if you consider that the entirety of recorded (ish) history is only a few thousand years long.

Updated comment to remove an order of magnitude.

Approximately four and a half billion years ago, some rocks and shit became friends and hugged each other so tight that they created the earth.

After a few hundreds of millions of years, life appeared on earth.

Then, four-ish billion years later, Nyasasaurus was like, "roar y'all."

And now there are birds. They're like, "caw y'all," and we're all like, "yo, that's a bird." Then the lizards are like, "me too bro."

The end.
