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.
