Cretoxyrhina is about 2.3× longer by these reference values.
Cretoxyrhina uses a 7 m upper reference, compared with 3.08 m for Nurse shark. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.
ON THE SAME SCALE
Human. Bus. Whale.
Pick your reference.
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.
THE NUMBERS
Side by side.
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; Nurse shark by recorded to 3.08 m / 10.1 ft. Length is reconstructed from fossils; mass is too model-dependent for a single figure here. Length is a recorded maximum; mass is a rounded adult reference.
Bite evidence
Cretoxyrhina: TuffShark does not scale a bite value without a published species-specific model. Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings.
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. A small mouth and powerful suction suit its bottom-feeding life.
