The term "Suborder Carnosaura" refers to a classification of reptiles that includes some of the most popular and well-known members of the dinosaur family. Some synonyms that could be used to describe this suborder include theropoda or "beast-footed," as well as saurischia or "lizard-hipped." Other related taxonomic terms might include the superfamily Tyrannosauroidea or the infraorder Tetanurae. While these terms may have slightly different connotations or implications, they all refer to the same group of carnivorous dinosaurs that evolved during the Mesozoic Era and left a dramatic impact on the Earth's prehistoric ecosystems.
