The first time I read (in school) about an asteroid hitting the Gulf of Mexico and causing the extinction of the dinosaurs, I looked at a map and sure enough the Gulf of Mexico looked like a big round hole where the asteroid must have hit.

Later I realized that the dinosaur-killing crater is much smaller and buried and hidden at the edge of the Gulf of Mexico. I also learned that the Gulf of Mexico was formed to due plate tectonics, not due to an impact. What an odd coincidence that the dinosaur-killing asteroid hit a location on the Earth that looks just like a huge crater, but isn't a crater at all.
