Sauria is also the name of Dinosaur Planet from the Star Fox series.

Sauria is a clade of the reptilian family tree, that includes all living diapsids, as well as their common ancestor and all its extinct descendants, which date back to Permian times. The ancestral saurian was probably a small lizard-like creature.

The clade is defined by a number of details in skull and skeleton, and include the two important clades Lepidosauromorpha and Archosauromorpha.

The term "Sauria" has previously been used in a generic sense to refer to a suborder of Squamata, including the lizards (Lacertilia) as opposed to the snakes (Ophidia), but this classification is no longer used, as Sauria so-defined is a paraphyletic group.
