Other mosasaur specimens have teeth with simpler or fewer ridges. But “none of these tooth morphologies approach the condition seen here,” the authors note.

But there was one mosasaur menu item that kicked up a long-running debate among paleontologists. I was reminded of the argument when I visited the San Diego Natural History Museum.

Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile. Along with other recent ...

A close-up view of Xenodens' teeth (Image credit: Nick Longrich) The fossils belonging to the newfound mosasaur were found in rock older than the K-Pg boundary, a term used for the mass extinction ...

Geologists have uncovered the fossil of a mosasaur, an ancient aquatic predator, in Mississippi. Often referred to as a “sea ...

A mosasaur species with saw-like teeth that was described by scientists in 2021 may have been based on forged fossils, and researchers are now calling for CT scans to determine the creature's origin.

Each mosasaur tooth corresponds to a pit in the jaw. “Even if the fossil is very poor quality, you can still count the correct number of teeth by counting the number of these pits,” he says.

Given the close skeletal similarities between mosasaurs and monitor lizards, ... To pick up these cues, mosasaurs would have flicked their ... had a mouth full of rounded teeth suited to crushing ...

Scientists have discovered a new species of mosasaur, a giant sea-dwelling lizard that dates back to the age of the dinosaurs, that stands out because of its unique, star-shaped teeth.

Those teeth did more than slice into prey. Zietlow notes that several Mosasaurus fossils have bite marks, both healed and unhealed, that were certainly made by other mosasaurs. One particular ...
