　　An American paleontologist and a team of Egyptians have found the most nearly complete fossilized skeleton of the primitive whale Basilosaurus isis in Egypt’s Western Desert, a university spokesman said on Monday.

　　The skeleton, which is 50 feet long, could throw light on why there are so many fossilized 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.
