  1. The theory of beaks are interesting (did other clades of dinosaurs have beaks? Yes, some did). And a beaked mammal called a platypus. Also feathers. All birds have feathers, but so did many Cretaceous dinosaurs that were not birds. Another fun fact with the Tertiary. At the K-Pg extinction, all surviving Pterosaurs went extinct, and with it, Sauropsid flight using webbing or skin membrane wings (bats use this now). Birds wings use flight feathers.
