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.

Can Pangea happen again?

The answer is yes. Pangea wasn’t the first supercontinent to form during Earth’s 4.5-billion-year geologic history, and it won’t be the last.

What did Earth look like before Pangea?

But before Pangaea, Earth’s landmasses ripped apart and smashed back together to form supercontinents repeatedly. … Each supercontinent has its quirks, but one, called Rodinia, assembled from 1.3 to 0.9 billion years ago and broken up about 0.75 billion years ago, is particularly odd.

What was the world called before it split up?
