With going to Mexico, and going to the Yucatan peninsula in particular, I've been interested in that whole extinction event that killed the dinosaurs, the impact zone is pretty much proven to have been on the north / northwest side of that region.
Reading about the
Chicxulub impact on Wikipedia I saw this map of the past world - which also led me to various maps of the globe going back hundreds of millions of years. I've always known that if you got in a time machine and went back millions of years and saw the world from above, it would be a totally different. Although, it looks like for the most part, when the dinosaurs made their exit, the world was a little more familiar compared to our contemporary view than I expected.
Things I didn't expect:
* A mcmassive lake down the middle of North America (is that a forerunner to Lake Winnipeg?)
* Europe and the Middle-east as an archipelago
* India is pretty far out!
Learning things is fun!
