PARIS: Scientists uncovered secrets of the breeding habits of gigantic marine lizards that lived during the time of the dinosaurs.
The research team looked at young specimens collected over 100 years ago, Wiley reported. These fossils were once believed to represent ancient birds, but an analysis of the jaws and teeth suggest they actually belonged to the ancient lizards, called mosasaurs.
“Their success as apex predators has been attributed to their rapid acquisition of aquatic adaptations, which allowed them to become fully pelagic. However, little is known about the breeding biology of derived, flipper-bearing mosasaurs, as the record of neonatal mosasaur fossils is extremely sparse,” the researchers stated in their study abstract.
The samples looked at in the study included fragmentary cranial remains from the Niobrara Formation. These specimens are some of the smallest ever discovered.
