How many teeth do a Mosasaurus have?
In each jaw row, from front to back, Mosasaurus had: two premaxillary teeth, twelve to sixteen maxillary teeth, and eight to sixteen pterygoid teeth on the upper jaw and fourteen to seventeen dentary teeth on the lower jaw.
What does a Mosasaurus eat?
Paleontologists have discovered the preserved remains of mosasaur stomachs which contain food like fish, sharks, cephalopods, birds, and even other mosasaurs. It’s likely that mosasaurs weren’t picky and would eat pretty much anything which could fit into their enormous mouths – which, it turns out, was a lot.

How do mosasaurs lay eggs?
It is the second largest fossil egg ever found and may have belonged to a mosasaur, a 10-meter-long marine predator. Some snakes and lizards, living mosasaur relatives, lay eggs with thin shells that hatch almost as soon as they are laid. The new find suggests mosasaurs may have, too.
How did mosasaurus give birth?
So which form of birth did mosasaurs employ? They could have come ashore to lay eggs but no egg-laying sites had ever been discovered. Because these baby mosasaur fossils were found in the open ocean where egg-laying is not possible, the circumstances suggest that mosasaurs may have been viviparous.
How big is a mosasaurus baby?
two feet long
In the pages of Palaeontology, the researchers briefly describe the fossils as baby mosasaurs that probably stretched just a little over two feet long, or about 22% of expected adult size.
