The Swedish latest Early Campanian mosasaur fauna is one of the most taxon-rich assemblages of mosasaurs known, rivalled only by the Maastrichtian "Mosasaurus shales" fauna of southwestern Niger, the late Maastrichtian Maastricht Formation of the southern Netherlands, the early Maastrichtian Ciply Phosphatic Chalk fauna of southern Belgium and the contemporary Mooreville Chalk fauna of west-central Alabama.
The mosasaurs were large, carnivorous reptiles at the top of the food chain and since all the Campanian species are known from several sites, it is likely that all of them lived in the entire basin.
The most common mosasaurs were the smaller-sized Clidastes and Eonatator.
The high diversity of mosasaurs in the basin can be explained by the dissimilarity in dentition and body size between the species, meaning that they would not have competed with each other for food.
