Members of the aquatic clade of reptiles Sauropterygia quickly evolved and diversified during the Triassic, acquiring different lifestyles and trophic roles with a cosmopolitan distribution. Although the first Triassic sauropterygian remains from the Iberian Peninsula were found more than a century ago, most of the relatively abundant recovered fossils have provided scarce taxonomic information. The finding of new fossil sites and taxa during the last decade, as well as the review of the previously known specimens, has allowed us to perform an update of the Iberian record of Triassic sauropterygians, a new faunal list being provided. All the major clades of Triassic sauropterygians are present in the Iberian Peninsula, including placodonts, pachypleurosaurs, pistosauroids and nothosauroids (i.e., simosaurids and nothosaurs). At least 13 different sauropterygian taxa are recognized here. The Iberian record of Triassic sauropterygians is composed by both endemic forms and species and genera also identified in other parts of the world, not only in some European regions, but also in the Middle East and China.
