| P.694 - §6 Throughout this so-called Eocene period
the evolution of mammalian and other related forms of life continued with
little or no interruption. North America was then connected by land with
every continent except Australia, and the world was gradually overrun by
primitive mammalian fauna of various types. |
The eocene epoch is between 55mya and 34 mya. (The UB says that the
eocene epoch is between 50 mya and 35 mya, covering 15 million years.)
This was the age of early mammals. |
