ancient whale in Peru, which could potentially hold the title of the heaviest animal ever recorded. According to a study published in the journal Nature, the estimated body mass of the extinct Perucetus colossus ranges from 85 to 340 metric tons (equivalent to 187,393 to 749,572 pounds). This places its heft on par with or possibly surpassing that of the blue whale, which has long been recognized as the animal with the greatest body mass. Giovanni Bianucci, the first author of the study, revealed this groundbreaking discovery, shedding new light on the size and magnitude of these prehistoric creatures.
How big is the colossal whale from the big whale?According to a new study, Perucetus, the colossal ancient whale discovered in Peru, may have weighed two to three times more than the present-day blue whale, which reaches a maximum weight of 149.6 metric tons (330,000 pounds). Giovanni Bianucci, an associate professor of paleontology at the University of Pisa, stated in an email to CNN that Perucetus could have weighed almost twice as much as a blue whale, three times as much as a giant sauropod dinosaur (Argentinosaurs), over 30 African bush elephants, or even up to 5,000 people. Due to its enormous body mass and undulatory, anguilliform swimming style, Perucetus likely swam at a slow pace. Its flexible body moved in curvy waves from head to tail. This groundbreaking research provides new insights into the size and weight of prehistoric creatures like Perucetus. Perucetus's bones are composed of exceptionally dense and compact bone, a characteristic known as pachyosteosclerosis, which is shared with sirenians like manatees, sea cows, and dugongs. This unique feature is not present in any living cetacean, according to
