Squalicorax is about 8.9× longer by these reference values.
Squalicorax uses a 5 m upper reference, compared with 0.56 m for Cookiecutter 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.
THE NUMBERS
Side by side.
WHAT THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Cookiecutter shark is represented by about 0.56 m / 22 in; Squalicorax by estimated to about 5 m / 16 ft. Weight is a rounded comparison reference. Body length and ecology are reconstructed from incomplete fossil evidence.
Bite evidence
Cookiecutter shark: Bite shape is documented; a comparable force maximum is not. Squalicorax: Bite traces show feeding, not maximum force.
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
Its bite removes a round plug; size alone does not predict ecological impact. Serrated teeth and bite traces show a broad, opportunistic diet.
