Although the word dinosaur means "terrible lizard," the name is somewhat misleading, as dinosaurs were not lizards. Rather, they were a separate group of reptiles with a distinct upright posture not found in lizards. Through the first half of the 20th century, most of the scientific community believed dinosaurs were sluggish, unintelligent, and cold-blooded. Most research conducted since the 1970s, however, has indicated that dinosaurs were active animals with elevated metabolisms and numerous adaptations for social interaction, and many groups (especially the carnivores) were among the most intelligent organisms of the time.
