PLATE VII. 
Mosasaurus Conybeare, 1822. 
A Surface-Swimming Mosasaurian. 
Lower Senonian to Upper Maestrichtian. 
The environment and pose of the animal are copied from Williston’s restoration, 
while the proportions and form of the various parts of the body and paddles are 
restored directly from the Mosasaurus lemonnieri Dollo, 1889, thus facilitating a 
comparison of the restorations. We may note also the elimination of the bifid 
tongue, which does not exist in living marine reptiles and is therefore not in accord¬ 
ance with the pelagic adaptation of the animal.
