NEW YORK (AP) – There could be a new contender for heaviest animal to ever live. While today’s blue whale has long held the title, scientists have dug up fossils from an ancient giant that could tip the scales. Researchers described the species – named Perucetus colossus, or “the colossal whale from Peru” – in the journal Nature on August 2. Each vertebra weighs more than 220 pounds (100 kilograms) and its ribs measure nearly 5 feet (1.4 meters) long.
