Baleen whale

Whales sing loud enough that their songs travel through the ocean, but knowing the mechanics behind that has been a mystery.

Scientists now think they have an idea, and it's something not seen in other animals: A specialized voice box.

Experts say the discovery, while based on a study that is too tiny to be definitive, will direct future research into how whales communicate.

A whale skull fossil estimated to be some 12 million years old has been found on a beach in the Chesapeake Bay in Maryland, according to a local museum.

The discovery was made in October by a Pennsylvania man, Cody Goddard, who was searching for fossils and shark's teeth, the Calvert Marine Museum said in a statement.

A blue whale has turned up in the Red Sea, the long spit of water separating Egypt, Sudan and Eritrea from the Arabian Peninsula.

Ancient whales had extremely sharp predator teeth similar to lions, Australian scientists said on Aug. 30 in a discovery they believe debunks theories the mammals used their teeth to filter feed like today's gentle giants.

It was big. It was weird. And this monster from the primordial seas was also a trend-setter.

Scientists on March 11 announced the discovery in southeastern Morocco of beautifully preserved fossils of a huge arthropod - the group that includes crabs, scorpions, insects, spiders, centipedes and more - that lived 480 million years ago.
