Suborder Sauria is a taxonomic group that includes all lizards. However, there are several synonyms that have been used in the past to refer to this group of reptiles. Some of these include suborder Lacertilia, lacertids, and scaled reptiles. The classification of lizards has been updated over time, and while Suborder Sauria is the currently accepted term, these synonyms are still occasionally used in scientific literature. It's important to note that while these terms refer to the same group of animals, they may have different connotations or implications in different contexts. Nevertheless, they all refer to the fascinating diversity of lizards found across the world.
