A transitional fossil would have nostrils in the back of the skull be transitional fossil would have nostrils at the top of the skull, see the transitional fossil would have nostrils at the front of the school day. The transitional fossil would have nostrils in the middle of the skull.
The transitional fossil would have nostrils in the middle of the skull, indicating a gradual transition from front to top placement. This would show the evolution of the nostril placement in whales over time.
