Overview

• A recent study revises the weight estimate of the ancient Perucetus whale, significantly lowering it from over 200 tons to 60-70 tons.
• The revision is based on a reevaluation of the whale's bone density and body mass, disputing earlier claims that it outweighed the blue whale.
• The blue whale, with a maximum weight of 270 tons, is confirmed once again as the heaviest animal to have ever lived.
• The study involved paleontologists from UC Davis and the Smithsonian Institution, who challenged the initial findings using new analysis methods.
• Despite the revision, the exact diet and lifestyle of Perucetus remain speculative without the discovery of its skull or teeth.
