One of the prominent living creatures during the Dinosaurs age is the Mosasaurs, a gigantic marine lizard that once roamed the oceans in which their way of giving birth was not traced. Paleontologists believed that these gigantic creatures gave birth to their young in the open ocean away from the shore based on the recently identified specimens at the Natural Museum History.
Mosasaurs can grow up to 50 feet long and populated most of the Earth waters before their extinction 65 million years ago. They are also among the best studied groups of Mesozoic vertebrate animal.
Based on this recent study, Mosasaurs did not lay eggs on beaches and that its newborn most likely did not live in sheltered nurseries near shore.
