A recently confirmed study makes paleontologists believe that the Mosasaurs gave birth to their little ones not on the coast or anywhere close to the coast. In fact these giant sea reptiles give birth in open oceans.
Mosasaurs when translated means river lizard. It is believed that these huge marine creatures have probably arrived from semiaquatic squamates also known by the name aigialosaurus. Researchers point out that aigialosaurus look like contemporary monitor lizards.
