The creature, with a 4-meter-long body, is believed to be an early form of whale that had not fully transitioned to living in water. Researchers believe it could help understand how the whale had evolved and spread. The team which found the fossil named it "Peregocetus pacificus," which means "the traveling whale that reached the Pacific." /VCG Photo
