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 new species — named Perucetus colossus, or “the colossal whale from Peru” — in the journal Nature on Wednesday. Each vertebra weighs over 220 pounds (100 kilograms) and its ribs measure nearly 5 feet (1.4 meters) long.
