Huge prehistoric whales found in Egyptian desert

Researchers working in the Sahara desert have uncovered dozens of fossilised remains thought to be the prehistoric ancestors of whales.

The whale bones were found in the Wati El Hitan in the Egyptian desert, once covered by a huge prehistoric ocean, and one of the finds is a 37 million-year-old skeleton of a legged form of whale that measures more than 65 feet (20 metres) long.
