saurian

The clade Sauria was traditionally a suborder for lizards which originally (before 1800) comprised crocodilians too. It has been redefined as the group containing the most recent common ancestor of archosaurs and lepidosaurs and all its descendants; as such it was commonly thought that Sauria is a crowned-base grouping of diapsids. However, recent genomic studies and comprehensive studies in the fossil record suggest that turtles are closely related to archosaurs, not to parareptiles as previously thought. As such Sauria can be seen as a crowned-group of all modern reptiles (including birds) within the larger total group Sauropsida, which also contains various stem-reptile groups.

Les Lacertiliens (Lacertilia) ou Sauriens sont un sous-ordre de reptiles diapsides de l'ordre des squamates. Leur classification fait débat car on sait aujourd'hui que ce groupe est paraphylétique. Ils font partie des squamates, aux côtés des amphisbènes (Amphisbaenia) et des serpents (Serpentes). Ce taxon regroupe environ espèces de « lézards » au sens large.

Sauria (z gr. sauros – "jaszczurka, jaszczur") – grupa zauropsydów z podgromady diapsydów.
