What unique feature defines the recovered teeth of Livyatan melvillei, excluding tusks?
Answer
They are the largest biting teeth of any known animal.
The teeth of Livyatan melvillei offer concrete, measurable evidence of its hypercarnivorous diet, contrasting with the inferred nature of its body size. These teeth are remarkable because, when tusks are excluded from the comparison set, they represent the largest biting teeth known in any animal species. This capability for tearing large flesh segments distinguishes Livyatan from its modern kin, which rely on suction feeding. The functional specialization suggests the animal used its massive jaws, capable of interlocking, to subdue and consume large prey items, such as medium-sized whales.
