Migrating herds of sauropods once travelled the American West

Sauropods (such as the iconic Apatosaurus) are among the very biggest creatures that ever lived. Their fossils have been found in the American West, preserved in the famous Jurassic-aged Morrison Formation and uncovered at places like Dinosaur National Monument. The geologic record tells us that this region was a seasonally dry floodplain at the time when sauropods roamed across it.

Many paleontologists have suggested that they would have had to migrate elsewhere to find food and water during the dry summer months. This week, a paper published in Nature presents geochemical evidence indicating that this migration did, indeed, take place.
