North American Dinosaurs

• During the early part of the Mesozoic Era (the Triassic Period), North America was joined with all the other continents in one super-continent known as Pangaea.
  
  
• By the Jurassic Period, Pangaea begun to break up into two smaller super-continents: Laurasia and Gondwanaland. North America was part of the northern super-continent, Laurasia, which also included Europe and Asia (except for India). However, the very beginnings of the Atlantic slowly appeared, as North America slowly begun to break-away from Europe.
  
  
• In the Cretaceous Period, Laurasia continued its break-up. The Atlantic eventually became a wide ocean separating North America from Europe.
