What do the great dinosaur fossil locations in the world have in common?
The badlands of Argentina are a popular spot for collecting dinosaur fossils.
First, they are in the middle of very stable continents. A stable continent is one without a lot of earthquakes, volcanic eruptions, or other major geological events that would destroy the fossils.
