    Mosasaurs were marine reptiles with generally long slender bodies propelled by two sets of paddles and a long tail.   Their heads were tapered towards the front.  They had two nostrils and like alligators and pleisosaurs, they needed to surface to breathe.  The fossil record indicates that there were a number of kinds of mosasaurs.   Mosasaur fossils have been found in North America, Europe and Africa.  Evolutionary statements on mosasaurs are merely speculation.
