SHARK VS 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 2.2× longer by these reference values.

Cretoxyrhina uses a 7 m upper reference, compared with 3.2 m for Sand tiger 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; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Length is reconstructed from fossils; mass is too model-dependent for a single figure here. Upper records vary by region and source.

Bite evidence

Cretoxyrhina: TuffShark does not scale a bite value without a published species-specific model. Sand tiger shark: A reliable comparable maximum was not found.

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. Its protruding teeth look dramatic, but appearance alone does not reveal bite force.
