Cairo - An American palaeontologist and a team of Egyptians have found the most complete fossilised skeleton of the primitive whale Basilosaurus isis in Egypt's Western Desert, a university spokesperson said on Monday.
Philip Gingerich of the University of Michigan excavated the well-preserved skeleton, which is about 40 million years old, in a desert valley known as Wadi Hitan (the Valley of the Whales) south-west of Cairo, spokesperson Karl Bates said.
"His feeling is that it's the most complete - the whole skeleton from stem to stern," said Bates.
The skeleton, which is 18 metres long, could throw light on why there are so many fossilised remains of whales and other ancient sea animals in Wadi Hitan and possibly how the extinct animal swam, he said.

Basilosaurus isis is one of the primitive whales known as archaeocetes, which evolved from land mammals and later evolved into the two types of modern whale.
But it looks like a giant sea snake and the palaeontologists who found the first archaeocetes thought they were reptiles.
Modern whales swim by moving their horizontal fluke up and down in the water, while fish swim by lateral undulations.
"The research team will use the new skeleton to study how it lived and swam, and possibly to learn why it is so abundant in Wadi Hitan," Gingerich said in a statement.
The statement said the skeleton will go to Michigan for preservation and replication. The original will then come back to Egypt for display.
| Wadi Hitan is rich in fossil remains |
Wadi Hitan is unusually rich in fossil remains from the period, trapped in a sandstone formation that then formed the sea bed. The fossils include five species of whale, three species of sea cow, two crocodiles, several turtles, a sea snake, and large numbers of fossilised sharks and bony fish.
It is a protected area to be developed as a national park under an Italian-Egyptian co-operative programme and it has been nominated as a Unesco World Heritage site because of its natural beauty and scientific importance.
