Pre­his­toric su­per­con­ti­nents

How It Works - - SCIENCE -

1

Pan­gaea

The last su­per­con­ti­nent ex­isted just 280 mil­lion years ago. Rep­tiles had just emerged, a mass ex­tinc­tion was im­mi­nent, and di­nosaurs were about to ap­pear.

2

Ro­dinia

This su­per­con­ti­nent cov­ered Earth around 1 bil­lion years ago, sup­port­ing the first multi-celled life on our planet. Plants emerged first, and an­i­mals soon fol­lowed.

3

Nuna

Also known as Columbia, this su­per­con­ti­nent dates back around 1.8 bil­lion years. At this point in Earth’s his­tory com­plex cells were just start­ing to emerge.

4

Kenor­land

This su­per­con­ti­nent ap­peared around 2.4 bil­lion years ago, around the time that oxy­gen lev­els started to rise in the at­mos­phere. Air be­came breath­able, but it trig­gered an ice age.

5

Vaal­bara

This su­per­con­ti­nent ex­isted 3.1 bil­lion years ago, just af­ter pho­to­syn­the­sis started to fill the at­mos­phere with oxy­gen. Only two pieces re­main, one in South Africa and one in Aus­tralia.
