Prehistoric Sea Monster Didn't Stick to The Oceans, Suggests Fossil Study.

#Mosasaurs were the apex predators of the oceans during the reign of the dinosaurs, but new research reveals dinosaurs weren't safe from them in rivers either.

Researchers from Sweden, the US, and the Netherlands analyzed isotopes in several mosasaur teeth from sites across North Dakota, confirming that these ancient sea monsters could also live in freshwater environments.

Mosasaurs were the apex predators of the oceans during the reign of the dinosaurs. But these massive aquatic reptiles weren’t limited to the sea, new research has revealed. In fact, mosasaurs were a terrifying threat to thirsty dinosaurs in rivers too. Read more from @ScienceAlert:

#Mosasaurs, giant marine reptiles that existed more than 66 million years ago, lived not only in the sea but also in rivers. This is shown by new research based on analyses of a mosasaur tooth found in North Dakota and believed to belong to an animal that could reach a length of 11 metres.

Ancient #BoneEatingWorms ate mosasaur, ichthyosaur and plesiosaur skeletons https://phys.org/news/2025-07-ancient-bone-worms-ate-mosasaur.html paper by Sarah Jamison-Todd et al.: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0326451

"These bone-eating communities are ancient, and have been on Earth for at least 100 million years. Before #whales existed, bone-eating #worms were eating into the skeletons of #mosasaurs, #ichthyosaurs and #plesiosaurs... New research has named seven of these burrow types... some are very similar to the burrows of living #Osedax worms."

New addition to the bookshelf, ‘Ocean Life in the Time of Dinosaurs’ by Bardet et al. First impressions are positive. It’s great to see obscure groups getting coverage with plenty of diagrams and artwork, not just the #plesiosaurs, #ichthyosaurs and #mosasaurs.

New review: Richly illustrated, Ocean Life in the Time of Dinosaurs justifies its place alongside existing titles by offering an entry-level book to these extinct creatures.

Sometimes real life interferes and you spend Easter laying a new floor. So this review will have to wait just a tad longer...

New #Mosasaur Species from Morocco Had Dagger-Like, Interlocking Teeth

A bizarre new plioplatecarpine mosasaurid from the #Maastrichtian of #Morocco https://www.sciencedirect.com/science/article/abs/pii/S0195667124000430

"Some #mosasaurs had teeth to pierce prey, others to cut, tear, or crush. Now we have #Khinjaria acuta, with a short face full of huge, dagger-shaped teeth."
