The Rise and Fall of the Bone-Crushing Dogs

The video explores the history and evolution of bone-crushing dogs, known as Borophaginae, which dominated North America during the Miocene epoch. It discusses their traits, hunting strategies, and eventual decline due to competition with modern canines and cats. The video also covers the evolution of canines, their global spread, and adaptation strategies that allowed them to survive while other subfamilies went extinct.
