TOKYO (AP) - Researchers say a museum in central Japan has 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 Wednesday.
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, said museum curator Ken Narita.
The oldest right whale fossil previously found was a skeleton that was uncovered in Italy that dates back about 4 million years, Narita said.
