The Birds That Lived in The Age of Dinosaurs

The video explores the concept of birds as the last living dinosaurs, highlighting their coexistence with ancient species. It discusses key fossil discoveries like Archaeor Nithra and EO Granovora, which provide insights into early bird evolution and diets. The rocks vs clocks debate is explained, focusing on the timing of modern bird evolution. The discovery of Vegavis AI in Antarctica is highlighted as evidence of bird diversification before the mass extinction. The video concludes with the idea that birds had already become diverse and complex before other dinosaurs went extinct.

What is the significance of Archaeopteryx in the study of bird evolution?

• It was the largest bird-like dinosaur discovered.

What is the 'rocks versus clocks' problem in bird evolution?

• A debate about the size of early birds

• A conflict between fossil evidence and molecular data on bird evolution timing

• A disagreement on the diet of early birds
