Megalodon is about 2.2× longer by these reference values.
Megalodon uses a 15.3 m upper reference, compared with 7 m for Cretoxyrhina. 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.
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; Megalodon by evidence-based upper estimate 14.1–15.3 m / 46–50 ft. Length is reconstructed from fossils; mass is too model-dependent for a single figure here. No complete skeleton exists; 15.3 m is an evidence-based maximum from museum specimens, not a tape measurement.
Bite evidence
Cretoxyrhina: TuffShark does not scale a bite value without a published species-specific model. Megalodon: Finite-element scaling produced a range, not a directly measured bite.
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. Nearly every whole-body number is reconstructed from teeth and comparisons with living sharks.
