- ... that highlights from the history of troodontid research include the discovery that troodontids (example pictured) were among the brainiest dinosaurs?
- ... that oviraptorosaurs were thought to be egg-eaters after the discovery of Oviraptor on a nest of presumed Protoceratops eggs, until the nest was recognized as belonging to Oviraptor itself?
- ... that highlights from the history of coelophysoid research include a bone bed preserving thousands of Coelophysis in New Mexico, the large Gojirasaurus, and the Asian coelophysoid Panguraptor?
- ... that the hypothesis that the pachycephalosaurian dinosaurs used their domed skulls in head-butting competitions was first proposed in a work of science fiction?
- ... that over the course of the history of stegosaur research, their iconic back plates have been thought to function as armor plating, to regulate body temperature, or to attract mates?

- ... that highlights from the history of ceratopsian research include the discovery of the iconic Triceratops (skeletal mount pictured), spike-frilled Styracosaurus, and vast bonebeds preserving thousands of Centrosaurus?
- ... that highlights from the history of hadrosaur research include the first dinosaur fossils to be mounted in a museum, the colossal Shantungosaurus, and Maiasaura nesting grounds in Montana?
