 TOKYO (AP) - Researchers at a museum in central Japan have right whale fossils that are at least 5 million years old, making them the oldest fossilized remains of the animal in the world, officials said.
Researchers working in Nagano prefecture (state) estimate the fossilized skull bones and jaw of a right whale on display at the Shinshushinmachi Fossil Museum to be 5 million to 6 million years old, museum curator Ken Narita said Wednesday.
The oldest right whale fossil previously found was a skeleton that was uncovered in Italy that dates back about 4 million years, Narita said.
