Ypresian

From Wikipedia, the free encyclopedia

The Ypresian is the first stage of the Eocene Epoch and usually corresponds to the Early Eocene subepoch, though sometimes the Lutetian is included therein.

It spans the time between 55.8 ± 0.2 Ma and 48.6 ± 0.2 Ma (million years ago). The stage is named after Ypres, Belgium. The famous Messel shales in Germany are from this age. Primates had appeared by 55 Ma, although the molecular clock and new paleontological finds state that they may have existed as early as the Late Cretaceous, 90 Ma.
