Okay, but what makes a bird… a bird? Hint: Dinosaurs!

Okay, but what makes a bird… a bird? Hint: Dinosaurs!

E14. What do feathers, toothless beaks, and a 66-million-year-old asteroid have in common. Paleontologist Dr. Daniel Field, University of Cambridge, joins Scott to unpack how birds evolved from dinosaurs, and why defining "bird" is trickier than you think.

In this episode you'll hear about:

  • Why Archaeopteryx had half the features of a modern bird and lacked the other half, and what that tells us about 150 million years of evolution
  • The "Wonderchicken," a tiny fossil from the border of Belgium and the Netherlands that rewrote what we know about birds surviving the asteroid impact
  • How micro CT scanning lets scientists digitally peer inside rocks to study fossils at micron scale without ever touching them
