Abstract
A new polycotylid plesiosaur from the early Turonian (Upper Cretaceous) of the region of Goulimima. Morocco, is described. The holotype of <i>Manemergus anguirostris</i> n.gen. et sp. comprises the subcomplete axial skeleton and partial appendicular skeleton of an articulated juvenile individual. Owing to the young age of the specimen, the nature of anatomical variation during ontogeny in plesiosaurs is discussed. The new taxo is characterised by its skull architecture combining a narrow, relatively short rostrum and a box-like post-orbital segment, and slender, smooth teeth. The state of preservation of the specimen hints at a relative in vivo stiffness of the the neck due to strong liagamentous intervertebral connections.
