Here a Mosasaurus cruises the rocky underwater shoreline of the Late Cretaceous Japanese Islands, looking for a meal.  The ammonites in the background appear to be wishing they were some place else! During the Late Cretaceous, the ocean off the coast of what would become Japan was host to many different species of ammonites...  and many of the same genera of marine reptiles (mosasaurs and plesiosaurs) as were found in the Western Interior Sea.
