Many of the planet’s most famous killer dinosaurs owe their success to deeply serrated teeth that specialized in tearing through the flesh and crunching on the bones of other dinosaurs. But not only did their teeth have saw-like cutting edges, the tissues within each tooth were arranged in a way that strengthened and improved the function of their fearsome chompers. The findings are published in Scientific Reports this week.
