Lemon shark is about 1.67× longer by these reference values.
Lemon shark uses a 3 m upper reference, compared with 1.8 m for Cladoselache. 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
Cladoselache is represented by about 1.8 m / 6 ft; Lemon shark by commonly to 3 m / 10 ft. Calling it a modern-style shark hides major evolutionary distance. The values are upper-end figures, not a typical adult profile.
Bite evidence
Cladoselache: No usable maximum-force model exists. Lemon shark: No standardized maximum is available for a fair cross-species comparison.
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
It was an early shark-like chondrichthyan with a streamlined body. Decades of field research make this one of the best-studied coastal sharks.
