In describing the significance of the Orca Bone Atlas, Herbert Maschner, Director of the Idaho Museum of Natural History, said: "You are collaborating in what we call the 'democratization of science'– bringing knowledge to anyone who wants it.". Each is filled with special sound-transmitting fat that allows underwater sound to be carried to the ear bones in the skull. But the Orca isn't actually a whale: it's in the dolphin family.
