Political Pangaea is a map created with both scientific and artistic purposes.

The scientific task is to explain with a strong visual impact the relationships between the ancient supercontinent called Pangaea and the present world continents with their countries and cities.
The period that was chosen for this map is the middle Triassic era (about 235 millions of years ago) just before the starting of the tectonic movements that would eventually end with the splitting of the supercontinent and the creation of Gondwana and Laurasia.
The map is based on the current theories on the continental drift and it carefully respects the overall position of the lands starting from a center point that unites the two coast lines of the Atlantic Ocean (which are the most remarkable correspondence between continent shapes now-a-day).

The artistic task is to represent inside the frames of a real Pangaea map all the countries and lands that we generally see when we look at a modern political map in a clear and recognizable way . 
The resulting graphic visual impact would make people play with the surprising connections between cities and people that now seem to be very far in our conceptions of the world. The curious unions with unexpected countries (such as New York in front of Morocco) create an instinctive association of ideas between regions that are different in terms of climates, landscapes and geographical distances. This shocking reconstruction of our vision of the world forces us to think about how huge the changes in our planet should have been in the past.
But in order to represent all the modern countries we know in a recognizable way we need to manipulate and modify here and there the pure scientific geographical shapes of the Triassic Pangaea: an "artistic" adaptation is needed.
Some of the countries we now know were not existing 235 millions years ago (like Iceland or almost all the Pacific ocean islands), other lands were under the seas or presented definitely different shapes and extensions. Representing modern countries in a Pangaea map in an absolute scientific way is impossible, but with some small local modifications we can insert the shapes of all modern countries inside the correct general positions of the tectonic plates.

The map of Political Pangaea is this: an artistic interpretation of the ancient supercontinent called Pangaea that shows us clearly and in a very direct way the real overall correspondences of the land masses of our planet according the current scientific theories.

The paleogeographic “half-globe” illustrates the configuration of the ocean basins and continents during the early Jurassic, 190 million years ago (Scotese, 2014c).  At this time, the northern continents (Laurasia) and the southern continents (Gondwana) were united to form the supercontinent of Pangea.

The colors on the paleogeographic half-globe illustrate: 

·deep ocean (oceanic crust) - dark blue,

·midocean ridges – blue,

·shallow shelves and the flooded portions of the continents (epieric seas) -  shades of light blue,

·coastal regions and continental areas near sea level - dark green,

·low-lying inland areas – green,

·plateaus and the foothills of mountains - tan,

·mountainous regions - brown.

The raised circular feature in eastern Canada is the Manicouagan impact structure (~200 mya).  Black lines indicate modern political boundaries and coastlines.

 

This paleogeographic map is one of many plate tectonic and paleogeographic maps produced by Christopher R. Scotese during the past 40 years.  This early Jurassic reconstruction is from the PALEOMAP PaleoAtlas for ArcGIS (Scotese, 2002; Scotese, 2008a-f).  This digital atlas, designed for use with GIS software, (ArcMap, ESRI), consists of  ~100 paleogeographic maps together with plate tectonic (Scotese, 2014b), paleolithological (Boucot et al., 2013), paleoceanographic (Scotese, 2014a; Scotese and Moore, 2014a,e), and paleoclimatic reconstructions (Scotese et al., 2014;Scotese and Moore, 2014b,c,d) .  The original paleogeographic map (rectilinear projection) was converted to a set of gores and plotted on the RealWorld half-globe.  The original set of maps can be downloaded from the Earthbyte website at https://www.earthbyte.org/paleomap-paleoatlas-for-gplates/  (Scotese, 2016).

 

In collaboration with RealWorld Globes,  the PALEOMAP Project will be producing a set of paleogeographic globes and half-globes.  Tell us which geological periods you would like to see plotted on a RealWorld globe or half-globe!
