Q: How did the climate change affect Alamosaurus and other fauna?
A: The climate change in the area where Alamosaurus lived became drier, and this caused changes in the fauna. Thomas M. Lehman describes it as "the abrupt reemergence of a fauna with a superficially 'Jurassic' aspect". These faunas are dominated by Alamosaurus and feature abundant Quetzalcoatlus in Texas. The Alamosaurus – Quetzalcoatlus association probably represents semi-arid inland plains.
