A team of paleontologists announced the discovery of the remains of a large marine fossil in the Peruvian desert that appears to have exceeded the mass of the blue whale - the modern record holder. The new species was named Perucetus colossus - "Peruvian Colossal Whale".
The bones of the ancient whale were first discovered more than 10 years ago by researchers from the University of San Marcos in Lima. But it took several years of intensive digging to fully uncover and recover the fossil remains from a rock mass in the desert in southern Peru that was once a seabed long ago.
As a result of the excavation, researchers were able to collect 13 individual vertebrae, four ribs and a whale femur. Each vertebra weighs more than 100 kilograms, and the ribs are nearly 1.5 meters long. The fossil remains are approximately 39 million years old.
The analysis showed that the pre-historic giant weighed between 85 and 320 tons. Unfortunately, the remains found have a very large margin of error, but if the actual weight was close to the upper limit of the estimate, then this animal was the heaviest ever found. For comparison, the largest blue whales weigh about 200 tons. At the same time, this fossil whale was only about 20 meters long. Blue whales grow to be up to 30 meters long. The difference in weight is due to the greater bone density of the fossil.
