Angolasaurus ("Angola lizard") is an extinct genus of mosasaur. Definite remains from this genus have been recovered from the Turonian and Coniacian of Angola,[7] and possibly the Coniacian of the United States, the Turonian of Brazil,[8] and the Maastrichtian of Niger.[9][10] While at one point considered a species of Platecarpus,[6] recent phylogenetic analyses have placed it between the (then) plioplatecarpines Ectenosaurus and Selmasaurus, maintaining a basal position within the plioplatecarpinae.[11]
Its wide geographic range make it the one of the only Turonian mosasaurs with a transatlantic range.[8]
