Utilizing 3D scanning technology, paleontologists have decoded the feeding habits of mosasaurs by analyzing the abrasion patterns on their teeth. This research reveals distinct dietary preferences among mosasaur species, highlighting variations where some primarily consumed shellfish, while others targeted scaled fish.
A collaborative effort by scientists from Utrecht University and the Natural History Museum Maastricht has led to insights into the dietary habits of different mosasaur species. They achieved this by studying the marks left on mosasaur teeth through 3D scanning methods. This investigation enriches our understanding of the biodiversity in the Cretaceous era and underscores the significance of the limestone deposits in Maastricht for paleontological research.
The Maastricht limestone areas, where the first Mosasaurus was discovered in 1766, are renowned as the birthplace of paleontology. These regions, located around the capital of Limburg on the Dutch-Belgian border, are among the world’s most thoroughly studied in terms of Cretaceous-era geology, which ended 66 million years ago.
This research adds new dimensions to our existing knowledge: the Maastricht mosasaurs exhibited discerning dietary choices. This finding is from a joint study conducted by researchers from Utrecht University, the Natural History Museum Maastricht, and their English counterparts from the University of Leicester. They are pioneers in examining mosasaur teeth abrasions.

Investigation into Mosasaur Dietary Habits
Dr. Femke Holwerda, a paleontologist at the Utrecht University Faculty of Geosciences, shares insights, “We were intrigued to know if the mosasaur species around Maastricht competed for food, or if their dietary choices were diverse enough to avoid conflict.” Lacking direct evidence from stomach contents, the researchers focused on subtle scratches on the teeth of these ancient reptiles found in southern Limburg (the Netherlands) and near Eben-Emael (province of Liège, Belgium).
Varied Diets in Ancient Seas
The study indicates dietary differences among mosasaur species, particularly between smaller ones, ranging from three to seven meters, and larger species, measuring eight to fifteen meters. However, dietary variations were also observed among the larger mosasaurs.
For instance, Prognathodon, characterized by its large conical teeth, appeared to have a significant portion of shellfish in its diet, showing a preference for seafood. On the other hand, Plioplatecarpus, with its slender, pointed teeth, exhibited notable wear, possibly indicating a diet rich in scaled fish.

Cutting-Edge Research Methods
The team initially created silicone rubber casts of the teeth, followed by 3D scanning. “Although this method had been applied to dinosaur teeth, our study was the first to utilize it for mosasaur teeth,” explains Anne Schulp, a fellow paleontologist at Utrecht University.
Enhancing Knowledge of Ecosystem Diversity
This study sheds light on the enigmatic Cretaceous period’s ecosystem. Schulp notes, “Our goal is to deepen our understanding of diversity. Studying animals from the same geological layers and period allows us to view the ecosystem as a whole, rather than focusing on individual species.”

Significance of Maastricht’s Limestone
The limestone deposits near Maastricht are extraordinarily valuable for paleontologists. Schulp remarks, “The mosasaur habitat is remarkably well-preserved in these deposits. The soft limestone here minimizes other causes of tooth wear, offering clearer insights.”
Role of Amateur Paleontologists
The abundance of fossils in this region also attracts numerous amateur paleontologists. John Jagt, curator at the Natural History Museum Maastricht, emphasizes, “Amateur, meaning ‘enthusiast,’ is crucial. Thanks to 250 years of dedicated amateur research, we’ve gained substantial knowledge about mosasaurs and other extinct life forms. Our museum greatly benefits from this, and in the Netherlands, amateur paleontology is legally encouraged, unlike in some other countries.”

thats pretty cool, i always thought all these big reptiles just ate whatever they could find. nice to see some detailed research going into it.
I’m not usually into science stuff, but this is actually interesting. Who knew mosasaurs had such varied diets? Great article!
gotta say, this is impressive. The limestone in Maastricht seems like a goldmine for paleontology. Can’t wait to read more about these discoveries.
Wow, this is really fascinating stuff! I had no idea mosasaurs were so picky with their food. It’s amazing what modern tech can reveal about the past.
