MAKE HYPOTHESES
Reptiles are ectotherms—animals with body temperatures influenced by their external environments. Early in the study of dinosaur fossils, many scientists assumed that because dinosaur skeletons resembled those of some modern reptiles, dinosaurs, too, must have been ectotherms. This assumption led scientists to conclude that many dinosaurs, being both huge and ectothermic, were slow-growing, slow-moving, and awkward on land. Because the most complete dinosaur skeletons occurred in rocks formed at the bottom of bodies of water, scientists hypothesized that dinosaurs lived in water and that water helped to support their great weight. When skeletons of duckbilled dinosaurs, called hadrosaurs, were discovered, this hypothesis gained support. Hadrosaurs had broad, flat ducklike bills, which, scientists suggested, helped them collect and eat water plants.
