☆ Researchers Dispute Claim That Ancient Whale Was Heaviest Animal Ever
  + stars: | 2024-02-29 | by ( Carl Zimmer | ) www.nytimes.com   time to read: +1 min
Last August, a team of paleontologists announced that they had discovered the fossilized bones of a gigantic ancient whale. Perucetus, as they named it, might have weighed over 200 tons, which would make it the heaviest animal that has ever lived. But in a study published Thursday, a pair of scientists have challenged that bold claim. The bones had many hallmarks of whales’ bones. Dr. Urbina and his colleagues reconstructed the full skeleton of Perucetus by studying the much smaller whales that lived at the same time.

☆ The partial skeleton of an ancient whale shows it could've weighed nearly as much as a Boeing 747, making it one of the heaviest animals ever

It may have weighed twice as much as a blue whale because of its dense bones. That's nearly as heavy as a Boeing 747 or twice as much as a blue whale, which typically weighs between 72 and 180 tons. That means the other fossils retrieved from the area may not offer clues to how P. colossus lived. A 3D model shows what a complete skeleton of Perucetus colossus would look like, above a blue whale and smaller Cynthiacetus peruvianus skeletons. No limbs were found near the P. colossus skeleton, but fossilized evidence suggests it likely had both front and back legs.

☆ Whale fossil may be the heaviest animal ever

CNN —A colossal ancient whale discovered in Peru might be the heaviest animal on record, according to a new study. What’s more, Perucetus likely weighed two to three times more than the blue whale, which today weighs a maximum of 149.6 metric tons (330,000 pounds). Giovanni Bianucci“Discoveries of such extreme body forms are an opportunity to re-evaluate our understanding of animal evolution,” wrote J.G.M. “It seems that we are only dimly aware of how astonishing whale form and function can be,” they added. The lifestyle of a colossal whaleThe findings suggest that gigantism or peak body mass among cetaceans had been reached around 30 million years earlier than previously thought, according to the study.
