The scapula of Pliosaurus macromerus from the Kimeridge Clay (Jurassic) is described for the first time. It differs in shape from the scapulae of all other Plesiosaurians by the anterior production of its dorsal process. This change in shape and the consequent increase in the pre-glenoid length of the pectoral girdle confers important functional advantages which are outlined. The locomotion of Pliosaurs is briefly considered, and it is suggested that the main propulsive force was from the hind limbs.
