Why was archaeopteryx an amazing find?

Answer 1

Archaeopteryx was the first animal discovered that had both defining bird and dinosaur traits, as if it was an evolutionary link (in reality, however, it was only closely related to the ancestor of birds). These traits include feathers, wings, and wishbones of birds, and the long tail, fingers, and teeth of dinosaurs. It was the first evidence that birds evolved from dinosaurs.

Answer 2

Archaeopteryx is often accepted as the earliest bird humans have discovered, so it marks a landmark in evolution.
