Fossil dinosaur teeth have revealed evidence that some species of dinosaur would have migrated.

Geochemist Henry Fricke and his team made the discovery be examining the ratio of two isotopes in the teeth, which allowed them to determine that the location in which the teeth were found was a great distance from where that dinosaur would have grown up. "In a theoretical sense, it's not hugely surprising. They are huge they would probably have eaten themselves out of house and home if they stayed in one place," he said.

"A collection of teeth from dinosaurs in the western United States has produced the first solid evidence that these ancient animals undertook seasonal migrations."
