abstract = {In this paper, a pectoral vertebra of a plesiosaur is described. It comes from an exposure of the upper
member of the Gijón Formation (lower Hettangian - basal Upper Sinemurian) in the coastal cliffs of the
Villar hamlet in the Villaviciosa municipality (Asturias, Northern Spain). The specimen is not diagnostic
further away from the superfamily level, and is assigned to a Plesiosauroidea indet. The Villar vertebra is
the first vertebrate remain from the Gijón Formation and the oldest Mesozoic vertebrate fossil found in
Asturias. Moreover, it represents currently the oldest record of plesiosaurs from the Iberian Peninsula,
predating another indeterminate plesiosauroid specimen from the basalmost Pliensbachian of Villaviciosa
(Asturias). It also represents the westernmost occurrence of Early Liassic plesiosaurs in the Tethys Ocean},
