An international team of scientists has revealed a challenger for the title of the largest animal that has ever existed. Surprise, it's a whale.
The Perucetus colossus, or "the colossal whale from Peru" was even larger than the reigning heavyweight champion, the blue whale, the researchers concluded in their article entitled "A heavyweight early whale pushes the boundaries of vertebrate morphology."
The research was based on some massive bones found over a decade ago in the Ica desert along the southern coast of Peru by the University of San Marcos’ Natural History Museum in Lima.
As the research showed, each vertebra weighs over 100 kilograms and its ribs measure nearly 1.4 meters long.
Thus, the scientists estimated that the ancient whale's weight range was between 94 and 375 tons, which means that Perucetus colossus could be much heavier than the largest blue whale ever recorded with a weight of 200 tons.
The researchers hypothesized that it weighed more because its bones are much denser and heavier than those of the blue whale.
In addition, skeletal features indicate that Perucetus is related to Basilosaurus, another early whale that was similar in length but smaller in mass.
Earlier in June in neighboring Chile, a species of herbivorous dinosaur previously unknown to exist in the Southern Hemisphere was discovered by archaeologists.
It was named Gonkoken nanoi, meaning "like a wild duck or swan," from the language of the Tehuelche, an indigenous people of eastern Patagonia.
