I had a wonderfully exciting message delivered to me recently! It began with my looking over a global map, surveying the shapes of today’s continental coastlines. I was trying to determine, out of curiosity, which piece of land in Africa was more than likely to have been connected to my home state of Florida before they split apart long, long ago. Eyeballing it for myself, it looked like the shape of the coast of Mauritania seemed to fit Florida perfectly.
Above map: line pointing to Florida and pointing to Mauritania to show how they once snugly fit with each other. You can also clearly see how all of Africa once snugly fit with the Americas. Image via Wikipedia Commons.
