When Birds Had Teeth

The video explores the evolution of birds from dinosaurs, starting with the discovery of Archaeopteryx in 1861. It discusses key fossil finds, such as Compsognathus and the work of paleontologists like OC Marsh and John Ostrom, which helped establish the link between birds and theropod dinosaurs. The video also covers the diversity of Mesozoic birds, including Enantiornithines and Ornithurines, and the impact of the Cretaceous extinction on bird survival. It concludes with the evolution of modern birds and the significance of fossil discoveries in understanding this process.
