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 SETS THEM APART
More than a size contest.
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.
Habitat and diet
Cretoxyrhina: Late Cretaceous oceans; large fishes and marine reptiles. Megalodon: Warm and temperate seas worldwide; large marine mammals, turtles and fishes.
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.
Fossils change the certainty
At least one animal is known from fossils. Fossil length, weight and bite estimates depend on which living analogues and scaling equations researchers choose.
