Ancient Whale Were Land Dwellers?

Could whales have been land dwellers once? Some scientists think so.. 

Feb. 4, 2009 -- A rare fossil of an ancient whale with a fetus still inside reveals that its species -- an ancestor to modern whales -- gave birth on land 47.5 million years ago, according to a paper published in the online journal PLoS.

The discovery, along with prior fossil finds, suggests the first whale ancestors were full-time land dwellers that might have been related to the early relatives of hoofed animals, such as sheep and cattle.
