Photogrammetric 3D models of skeletal fragments of a plesiosaurid

Web visualization of the photogrammetric 3D models of fossil remains representing part of the skeleton of a marine reptile from the family Elasmosauridae (Upper Cretaceous, Snow Hill Island Formation) from the Cape Lamb locality on Vega Island, Antarctica. The model shows a fragment of the pubic bone, sections of the ribs, a caudal vertebra, elements of the pelvic girdle (ischium and femur), and a flipper phalanx. Elasmosaurid plesiosaurs grew up to 6 m in length and are distinguished by hyperphalangy, an evolutionary adaptation that increased the surface area of their flippers.
