However, for many years, we have been finding a number of fossils of various primitive whales (archaeocetes) between 25 and 45 million years old, and somewhat different from modern whales, e.g. with very distinctive teeth. An example of these early whales would be Place the fossil picture strip of at about 36 mya Dorudon. Dorudon on your timeline (actual range about 39-36 of years ago). Dorudon lived in the mya); (“mya”=millions shallow warm seas around the world. This is supported by their fossils usually found in deposits indicative of fully marine environments, lacking any freshwater influx. They were probably distributed throughout the tropical and subtropical seas of the world.
