Camarasaurus Migrated 300km Seasonally

Research has been published stating that "the 18-meter-long sauropodomorph, Camarasaurus, migrated long distances seasonally each year, like migratory birds."

The investigation was conducted by a team from the University of Colorado in the US.
They analyzed a substance called "oxygen isotopes" in tooth fossils to identify and estimate which land's water they drank.

As a result, it was found that Camarasaurus migrated from what is now Wyoming and Utah in the United States to the western mountains.
"The reason for the migration was to obtain food and water," the research team speculates.

They state that "it is highly likely that they left the lowlands during the dry season because the plants that Camarasaurus ate would decrease, and moved to the mountains where there were more plants, returning to the lowlands when it rained."
