Some animals are specialists at eating particularly tough foods like shells, seeds, and bones. Adaptations for a durophagous diet come in many forms in almost all major groups of life. This episode, we discuss how so many animals tackle tough foods, what behaviors and anatomy help them to do it, and the importance of durophagy for understanding fossils and the history of Earth ecosystems.

In the news: fossil boas, walking fish, cooked birds, and early arthropods.
