Answer by Adriana Heguy:

No. The ancestors of whales were land mammals. The earliest known whale ancestor lived 50 million years ago and was called Pakicetus (the fossil is from Pakistan): http://www.amnh.org/explore/news…

After Pakicetus, the next fossil that is in the whale lineage is Ambulocetus (http://www.amnh.org/explore/news…). It looked a bit like a crocodile, I think.

UC Berkeley has a very nice page on the evolution of whales: http://evolution.berkeley.edu/evolibrary/article/evograms_03
