At the end of the dinosaur age, gigantic beasts roamed the southern half of the North American continent. From Utah to Texas and New Mexico, these giants shook the earth under their immense weight, towering above predators and neighbors alike. It was the reign of Alamosaurus, America’s biggest dinosaur.

From group nesting in Argentina to fast-growing babies that succumbed to Madagascan droughts, these fossils have left their mark and are helping scientists to uncover the secrets of these little giants.

In one small corner of Burma, scientists have discovered something incredible: The whole wings of two tiny birds preserved in amber. These fossils give us another important glimpse into Cretaceous forest ecosystems.
