Fossils reveal a whale inside a whale, eaten by a shark: Grave of 40-million-year-old marine creatures found in Egypt

A 40 million-year-old early whale has been discovered in Wadi al-Hitan, Egypt, known as the Valley of Whales.

And fossils suggest the vast creature – known as Basilosaurus – is a genus of early whale and may have eaten another of its kind, before becoming lunch for a shark.

The remains are enabling scientists to explore the food chain of this time, with fossils of crabs and sawfish found inside the whale, as well as the small whale bones.

It is likely the small whale bones belong to a foetus, but the researchers have not ruled out the larger whale eating the smaller one.

Wadi al-Hitan was first discovered by scientists in 1902 and since then, 10 fossilised whales have been found in the marine fossil ‘graveyard’ in Fayoum.
