A mosasaur fossil collected in Kaizuka, Osaka and stored for 35 years has been reanalyzed. A premaxilla bone was confirmed for the first time in Japan, and the specimen may be a new species of Prognathodon, the heavy-jawed group nicknamed the T. rex of the seas.

In a 2004 book, a Japanese paleontologist described his country's dinosaurs in modest terms. Two decades on, Kamuysaurus and Yamatosaurus put Japan on the global dinosaur map.
