Oneirosaurus was a fierce marine lizard that swam in the warm seas of Colombia about 87 million years ago. It was a mosasaur, a relative of modern snakes and lizards, and it hunted fish and other sea creatures with its sharp teeth.21

Dintlha tse di monate

1

Oneirosaurus had a unique feature: two holes in its skull for nerves X, XI, and XII to exit, a trait not seen in any other plioplatecarpine mosasaur.1

2

Its name means 'dream lizard,' because the scientists who described it thought finding such a complete fossil was like a dream.1

3

Oneirosaurus lived during the Coniacian stage, about 89.8 to 85.7 million years ago, in a shallow sea that covered what is now Colombia.2

4

The only known fossil of Oneirosaurus is a nearly complete skull with a lower jaw and a disarticulated atlas (the first neck vertebra).2

5

Oneirosaurus belonged to a group of mosasaurs called Plioplatecarpinae, which were medium-sized, fast-swimming predators.2

6

Its teeth had two sharp edges (carinae) arranged 180 degrees apart, perfect for slicing through flesh.2

Oneirosaurus was named in 2025 by María Eurídice Páramo Fonseca and colleagues, based on a skull found in the Galembo Formation of Colombia.1
Go sa ntse go ganetsanwa
Scientists are still debating exactly how Oneirosaurus is related to other plioplatecarpine mosasaurs, especially its closeness to Yaguarasaurus columbianus and Ectenosaurus clidastoides.1
