The specimen was found in the Sandwich Bluff area of Vega Island east of the \nAntarctic Peninsula from Late Cretaceous (Maastrichtian) marine deposits from the upper Snow Hill Island Formation. \nThe plesiosaur skeleton is represented by a nearly complete torso, partial paddles, and neck and tail sections. Along the \nventral margin of the torso are articulated gastralia, some that are unusual in being forked. Numerous small gastroliths \nare associated within the trunk cavity, indicating that even juveniles ingest gastroliths. Coupled with other known \nspecimens, the skeleton indicates shallow marine environment may have been an area where marine reptiles had their \nyoung, and the young remained until reaching maturity prior to facing open marine environments. The morphology of \nthe specimen suggests the skeleton represents a juvenile Mauisaurus, an elasmosaurid plesiosaur taxon originally \ndescribed from New Zealand and endemic to the Weddellian Province of the austral region.", "description": "4 p.", "publisher": { "@type": "Organization", "name": "U.S. Geological Survey" }, "author": [ { "@type": "Person", "name": "Case, Judd A.", "givenName": "Judd A.", "familyName": "Case" }, { "@type": "Person", "name": "Reguero, Marcelo", "givenName": "Marcelo", "familyName": "Reguero" }, { "@type": "Person", "name": "Sawyer, J.
