Here's a close-up of pakicetus inachus who is part of my illustration that shows the evolution of toothed whales. This early on they look nothing like a whale. They are small land animals that were probably semi-aquatic.The inner ears of pakicetus are very interesting, they share the same characteristics only found in cetaceans. The large auditory bulla is formed only from the ectotympanic bone. It may seem like a tiny detail, but this is a big clue that links them to whales.Pakicetus done in marker, colored pencil, and white pen.
