International borders are man made constructs, lines drawn in the dirt which are easy to ignore until a nation's police force cracks your head open for stepping over the line.
And to make matters even more confusing these borders are constantly changing thanks to international conflicts and government expansion.
But you know what would make that whole international border thang even more confusing? If these invisible lines were drawn on the supercontinent of Pangea.
The geography lovin' folks at Open Culture created this map a few years back showing Where Today's Countries Would Be Located On Pangea after they had a strange dream about Argentina making out with South Africa. *shivers*
