Tethysaurus is an extinct genus of tethysaurine mosasauroid from the Early Turonian (Late Cretaceous) period. The only species is Tethysaurus nopcsai . .An average-sized mosasaur of 3 m (9.8 ft) length, Tethysaurus displays a number of basal and derived features that led to an initial classification as an intermediate stage between primitive aigialosaurids of the Cenomanian and derived mosasaurids from the Turonian to the Maastrichtian.[
