Holarctic Fossil Mammals and Paleogeee Series Boundaries

摘要

Mammalian paleontologists have long attempted to correlate major turnover events in the evolution of Holarctic mammals to Paleogene Series boundaries. However, current understanding of the evolution and biostratigraphy of Holarctic Paleogene mammals indicates that no Paleogene Series boundary correlates to a major evolutionary turnover in mammals.
