Ancient 'Blue Dragon' Unearthed: Japan's Terrifying Sea Monster
Well-preserved remains of a 72-million-year-old mosasaur, an extinct marine reptile, have been unearthed in Japan. Named Wakayama Soryu, meaning "blue dragon," this fossil represents the most intact skeleton of a mosasaur ever found in the northwestern Pacific region. The discovery was made in 2006 beside the Aridagawa River in Wakayama Prefecture.
