I don't really follow the logic of this.

Hi Crowan,

It's like this: many millions of years ago, all of the continents were joined in one 'supercontinent' called Pangea. During The Permo Triassic and Jurassic Periods (180-200 million years ago) it broke up into two 'supercontinents', Laurasia (northern) and 'Gondwana' (southern.) Since all continents were once joined in this Pangean continent, it is no surprise that all other continents fit into Africa.

It is for this reason that most pre-Jurassic dinosaurs are found scattered over the globe, whilst post-Jurassic and Cretaceous dinosaurs (T-Rex, etc) are found in North America.

Hope this makes more sense.

Love,
Patsy.

I know about Pangea, Laurasia and Gondwana. I just don't understand why it therefore follows that all other continents fit into Africa.

I think what Patsy's saying (she can correct me if I'm wrong) is that when it split into two supercontinents, it split fairly evenly in two, and Africa is one of those halves... though it doesn't figure with me either at the minute as I'm trying to figure out where Russia fits in. :confused:

But that isn't so.
Gondwana included most of the landmasses in today's Southern Hemisphere.
That is: Antarctica, South America, Madagascar, Australia, Arabia and the Indian Subcontinent, as well as Africa.
It doesn't therefore follow that Africa is as big as all the rest.
Asia is the largest continent, at 44,579,000 square km. Africa is 30,200,000 square km.

My tiny understanding just cannot grasp any of it-the business of vastness of Africa...
...it is amusing how we tend to believe most of the material that we read on internet.
