Dinosaurs have been found on every continent on Earth, including Antarctica, because their fossils are preserved in rocks of the right age all around the globe. The richest and most famous fossil sites are in places where those rocks are exposed at the surface, especially the dry “badlands” and deserts of a few key regions.

Global dinosaur hotspots

  • Every continent has yielded dinosaur fossils, with named species from at least 51 countries, including Antarctica. This shows dinosaurs were a truly global group during the Mesozoic Era.
  • Particularly rich fossil records come from large countries with extensive Mesozoic rocks, such as the United States and China, each with more than 320 named dinosaur species.

North and South America

  • Western North America (from Montana and North Dakota down through Colorado, New Mexico, Arizona, and Texas) is one of the most productive dinosaur regions, especially formations like the Morrison and Hell Creek. Many famous dinosaurs such as Stegosaurus and Brontosaurus were first described from these rocks.
  • Argentina and neighboring desert regions in South America also hold vast fossil beds, where arid conditions and erosion expose bones at the surface rather than hiding them under thick vegetation.

Asia and Europe

  • Northern China, especially Liaoning Province, is a major hotspot for exquisitely preserved fossils, including feathered dinosaurs that helped clarify the link between dinosaurs and birds. These early Cretaceous deposits record around 20 million years of dinosaur-rich ecosystems.
  • Europe has important sites as well; in the United Kingdom, most dinosaur fossils come from southern England, including coastal areas like the Isle of Wight and the Jurassic Coast of Dorset. Some of the first dinosaur bones ever recognized scientifically, possibly Megalosaurus, were found in Oxfordshire quarries in the 1600s.

Why these places, not others?

  • Dinosaur remains are actually widespread in the crust, but the best places to find them are where Mesozoic rocks are eroding just enough to reveal fossils without completely destroying them. Dry, sparsely vegetated landscapes make it much easier to spot exposed bone and fossil-rich layers.
  • In contrast, regions that were eroding during dinosaur times, or are now buried under thick soils, forests, cities, or younger sediments, often yield fewer accessible fossils even though dinosaurs once lived there.
