SHARK VS SHARK

CretoxyrhinavsEpaulette shark

Length, weight and bite evidence—plus context from a human, city bus and blue whale. Every number below carries its uncertainty with it.

QUICK VERDICT

Cretoxyrhina is about 6.5× longer by these reference values.

Cretoxyrhina uses a 7 m upper reference, compared with 1.07 m for Epaulette shark. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.

WHAT THE DATA CAN SAY

Size is not the whole animal.

Length and weight

Cretoxyrhina is represented by estimated to about 7 m / 23 ft; Epaulette shark by reported to 1.07 m / 3.5 ft. Length is reconstructed from fossils; mass is too model-dependent for a single figure here. Mass varies strongly with size and is shown only as a reference.

Bite evidence

Cretoxyrhina: TuffShark does not scale a bite value without a published species-specific model. Epaulette shark: No standardized maximum is used.

Living versus extinct

At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.

Ecology changes the matchup

Teeth and rare skeletal material point to a large, fast lamniform predator. It can use its fins to walk across reef flats and tolerate low oxygen.
