Cool oasis for Cretaceous feathered dinosaurs
The Jehol Biota, an ancient ecosystem in Liaoning province in northeastern China, includes a dense and diverse array of Cretaceous flora and fauna and is a hot spot of feathered dinosaur fossils. A new study reconstructs a cool climate and high elevation at the site, providing critical environmental context for the wide array of dinosaurs preserved there.
