Things keep turning up in the fossil world. Scientists have gone and dug up another transitional fossil for the whale, this one called the Maiacetus.
The oldest fossil is the Sinonyx, a wolf-sized critter. Then there is the Pakicetus (the oldest cetacean) followed by the Ambulocetus natans (the walking whale that swims). At about 46 to 47 million years ago the Rodhocetus lived, and this same time period is where the Maiacetus lived. Then the Basilosaurus and
the Dorudon left their marks.
All this information (minus the Maiacetus) is in an excellent article by Raymond Sutera called The Origin of Whales and the Power of Independent Evidence.
For Information on the Maiacetus check out The Backward Whale at The Loom blog, Fossil foetus shows that early whales gave birth on land at Not Exactly Rocket Science. And Maiacetus, the good mother whale at Laelaps. And lastly Amazing Fossil Finding: Proto Whales Gave Birth on Land, not at sea at Greg Laden's Blog.
