Did dinosaurs live on Pangea?

Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.

Who created the 7 continents?

In 1912, German scientist Alfred Wegener proposed that Earth’s continents once formed a single, giant landmass, called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today. The video below shows how this happened over one billion years.
