All the continents were joined together as one supercontinent (Pangea) when the dinosaurs appeared. Since then, through tectonics, Pangea has broken apart to form the landmasses we know.

When dinosaurs first appeared, the Earth was made up of one big continent. All the landmasses were joined together. This big continent is known as Pangaea. As time went by, Pangaea gradually broke apart into the landmasses we know today. First it separated into a northern and a southern continent. The southern continent, which included Australia, was known as Gondwana. During the Cretaceous Period, Gondwana gradually broke up into the present landmasses of Africa, South America, India, Antarctica, and Australia. Antarctica and Australia were the last continents to separate, starting about 100 million years ago.

there was only a supercontinent at first. Look at the globe, all the continents fit together somehow. Like a giant puzzle.
