The evolution of the ratite birds has been widely attributed to vicariant speciation, driven by
the Cretaceous breakup of the supercontinent Gondwana. The early isolation of Africa and …

Alligatoroidea, a stem-based group including living alligators and caimans and all taxa
closer to them than to Crocodylus or Gavialis, includes seven living species and a large …

Abstract The Late Cretaceous was a time of tremendous global change, as the final stages
