Igdamanosaurus aegyptiacus ("lizard from Igdaman") is a durophagus globidensine mosasaur from Maastrichtian-aged marine environments of Africa. Its scrappy fossil remains are found in the Late Cretaceous-aged Duwi Formation of Egypt, Phosphates Formation of Morocco, and the Dukamaje Formation of Niger. It has blunt, rounded teeth similar to those of the mosasaurines Globidens and Carinodens, and were better suited for crushing armored prey like molluscs and turtles, rather than fish or other reptiles normally preyed on by other mosasaurs. It is named after the village of Igdaman (sometimes called In Dama), near which it was found.
