Ectenosaurus
Based on the size of the preserved skull, about 74 centimeters in length, "Ectenosaurus" would have reached sizes of 5,7 meters in length. It was a rare genus of mosasaur with several unique characteristics that clearly separate it from other mosasaur genera. The most prominent of these features is its elongated jaws, elongated in a similar vein to other mosasaurs with elongated jaws, such as "Plotosaurus" and "Pluridens".
