The Ambulocetus( 50 million years or less)
16 years after the finding of Pakeicitus they find the fossil for this. it's inner ear bone had developed to be able to hear underwater. These whales drank freshwater. It was a poor swimmer and had to be in shallow water to hide to catch it's food. It moves like an alligator on land which means it barley can move on land. -

The Rodhocetus
About 45 years ago
Rodhocetus was the first ocean whale but its limbs could support it on land also, that could swim and have a shorter neck. it swam using its flipperlike feet and long tail which it used as a rudder. The nasal openings had begun to move up the skull, in what would eventually become the whale's signature spout. -
Todays Whale
None of the whales i have listened about are direct ancestor of the whales we know today; they may be side branches of the family tree. But the important thing is that each fossil whale shares new, whale-like features with the whales we know today, and in the fossil record, we can observe the expantion of these water adaptations that led to modern whales. -
The Basilosaurus
38 years ago.
This whale is the top predator and 50 foot long mammal,
It swam like an eel, but its jawbone, ribs and and small hind limbs make it a mammal. It straddled two worlds; though it only lived in the water, it couldn't dive to any substantial depths, or could its hind limbs support it on land. -
The Dorudon
The Dorudon was fully aquatic whales that had very small hind limbs projected slightly beyond the body wall. They were no longer able to be on the land.
