Description
Summary:Elasmosaurs are recorded for the first time in the Lachman Crags Member (Beta Member) of the Santa Marta Formation (lower Campanian) and in the Herbert Sound Member of the Snow Hill Island Formation (upper Campanian). These are the first elasmosaurids from James Ross Island, Antarctic Peninsula. These records greatly improve our knowledge of the taxonomic diversity of plesiosaurs of the Santa Marta Formation and Herbert Sound Member of the Snow Hill Island Formation, and extend the lower limit of the record of Elasmosauridae in Antarctica to the lower Campanian, making this the oldest record of an Antarctic elasmosaur. Plesiosaurs are a clade of reptiles adapted to the marine environment. Their record extends from the Upper Triassic to the Upper Cretaceous and their geographical distribution is cosmopolitan, having been recorded in all continents, including Antarctica (Welles 1952, 1962;
