50 million years ago, the Pakicetus had nostrils toward the front of it's skull Gray whales, modern-day descendants of the Pakicetus have nostrils toward the back of the skull. The Aetiocetus lived 25 million years ago, and it's nostril was in the middle of the skull. In this case, the Aetiocetus serves as a ______________.
