During the Battle of France, on June 14, German forces occupied Paris.
Archaeoceti -LRB- `` ancient whales '' -RRB- , or Zeuglodontes in older literature , is a paraphyletic group of primitive cetaceans that lived from the Early Eocene to the late Oligocene .. paraphyletic. paraphyletic.

Representing the earliest cetacean radiation , they include the initial amphibious stages in cetacean evolution and are thus the ancestors of both modern cetacean suborders , Mysticeti and Odontoceti .. radiation.

This initial diversification occurred in the shallow waters that separated India and Asia , resulting in some 30 species adapted to a fully oceanic life ; though both echolocation and filter-feeding evolved during a second radiation .. radiation.

All archaeocetes from the Ypresian -LRB- 56 -- 47.8 mya -RRB- and most from the Lutetian -LRB- 47.8 -- 41.3 mya -RRB- are known exclusively from Indo-Pakistan , but Bartonian -LRB- 41.3 -- 38.0 mya -RRB- and Priabonian -LRB- 38.0 -- 33.9 mya -RRB- genera are known from across Earth , including North America , Egypt , New Zealand , and Europe ..

Although there is no consensus regarding the mode of locomotion cetaceans were capable of during the late Lutetian , they were very unlikely to be nearly as well-adapted to the open ocean as living cetaceans ..

They probably reached as far as North America along coastal waters  : either around Africa and over to South America , or , more likely , over the Tethys Sea -LRB- between Eurasia and Africa -RRB- and along the coasts of Europe , Greenland , and North America .. Some researchers are convinced , based on morphological similarities between archaeocetes -LRB- stem cetaceans -RRB- and neocetes , that the two living suborders of cetacean -LRB- the crown cetaceans -RRB- emerged from within Archaeoceti and therefore consider Archaeoceti paraphyletic or a non-natural group .. paraphyletic. paraphyletic. neocetes.

Other researchers argue , despite these morphological similarities , that no archaeocete fossil have been placed within Neoceti , and therefore that the radiation of extant whales can be described independently of Archaeoceti .. radiation.
