Support Recently discovered bird fossils are about 20 million years older than the fossils of the birdlike dinosaurs from which the birds are generally claimed to have descended. ██ █████ █████ ██████████ ███████ █████ ████████ ██ ███ ███████ ████████ ██ ████ ████████████████ ████ ██ ████ █████████ ████ ███ █████████
The argument concludes that no birds descended from dinosaurs, counter to a common claim. This is based on the discovery that some bird fossils predate the fossils of dinosaurs from which birds were previously thought to have descended, so those birds couldn’t have descended from those dinosaurs.
The argument takes evidence proving that certain birds didn’t descend from certain dinosaurs to support a conclusion that no birds descended from any dinosaurs. However, it’s still totally possible that other birds were descended from those birdlike dinosaurs, or even that the newly discovered birds were descended from even older dinosaurs.
