In the Egyptian desert is a place called Wadi Hitan, an eroded mass of rock that was once on the bottom of a shallow sea. Among the denizens of that sea were the early whales known as Basilosaurus.
Wadi Hitan has produced dozens of Basilosaurus
skeletons, making it one of the key sites for the study of whale evolution.
