New research published today in Scientific Reports describes Kamuysaurus japonicus, a species of hadrosaur, or duck-billed dinosaur, pulled from Japan’s Hakobuchi Formation.
The nearly complete fossilized skeleton was found in 72-million-year-old marine deposits, suggesting the creature foraged along the shoreline, a rarity for hadrosaurs.
It’s the “largest dinosaur skeleton ever found in Japan,” according to a Hokkaido University press release.
Kamuysaurus japonicus and its close relatives likely traveled through Alaska, which connected Asia to North America during the Late Cretaceous.
