Episode notes
INSIGHT

From Lumbering Lizards To Active Animals

  • 19th-century views cast dinosaurs as slow, swamp-dwelling lizards which shaped public imagination for decades.
  • New fossil evidence overturned that picture, revealing active, diverse, often bird-like dinosaurs.
INSIGHT

Feather Anatomy And Development

  • Feathers develop from skin placodes and follicles and form a hollow central shaft with branching structures.
  • Modern feathers have complex branching (barbs, barbules, hooklets) that create the vane used in flight.
INSIGHT

Chinese Fossil Beds Changed Everything

  • The Liaoning fossil beds in northeast China preserved thousands of exquisitely detailed specimens in fine lake sediments and volcanic ash.
  • That preservation produced abundant feathered dinosaurs and revolutionised understanding of feather evolution.
