The Ezomikasa Dragon (エゾミカサリュウ Ezomikasa Ryuu) is the last dinosaur to appear in the series, Dinosaur Expedition Born Free.


Dinosaur Expedition Born Free

Ezomikasa Dragon appeared from a mountain side near Tokyo. For the Born Free's final expidition, they had to stop the massive therapod from destroying the city.


  • The Ezomikasa Dragon would trigger the Dinosaur War.
  • He is based on the Taniwhasaurus species T. mikasaensis, which was discovered in Japan in 1976 and classified as "Yezosaurus mikasaensis". At the time, the connection between T. mikasaensis and the other species of Taniwhasaurus wasn't known, and the fossil was speculated to be that of a tyrannosaurid dinosaur, explaining Ezomikasa Dragon's upright posture. In reality, T. mikasaensis was a species of Mosasaur, and received its current binomial name in 2008.
