Data from: Widespread loss of mammalian lineage and dietary diversity in the early Oligocene of Afro-Arabia
Diverse lines of geological and geochemical evidence indicate that the Eocene-Oligocene transition (EOT) marked the onset of a global cooling phase, rapid growth of the Antarctic ice sheet, and a worldwide drop in sea level. Paleontologists have established that shifts in mammalian community structu...
