The Åsen site is believed to have been a murky river mouth during the Campanian.
Teeth and vertebrae of small-sized (probably juvenile) Clidastes propython mosasaurs have been found at Åsen, which suggests that the area offered some protection against predation by larger mosasaurs and other predators, possibly due to the murky waters produced by some nearby river system.
This murky setting also seems to have been preferred by the many species of benthic sharks and rays recovered at Åsen.
Particularly, Rays significantly more common at Åsen than elsewhere.
It is probable that they preferred the murky and estuarine environment there, similar to the environments preferred by their modern relatives.
The sharks and rays at Åsen probably fed on fish and invertebrates, which occur with less diversity (though still large numbers) at Åsen than elsewhere.
They might have primarily fed on soft-bodied invertebrates, less likely to be preserved in the fossil record.
