Squalicorax is about 1.25× longer by these reference values.
Squalicorax uses a 5 m upper reference, compared with 4 m for Bull shark. A clean mass ratio is not shown because at least one weight is not reliably reconstructed.
ON THE SAME SCALE

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
Bull shark is represented by reported to 4 m / 13 ft; Squalicorax by estimated to about 5 m / 16 ft. The 4 m figure is a reported maximum; typical mature animals are smaller. Body length and ecology are reconstructed from incomplete fossil evidence.
Bite evidence
Bull shark: The upper value is a theoretical posterior bite for the largest specimen in a 73–285 cm study series—not a universal adult bite. 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 freshwater range is exceptional among large coastal sharks. Serrated teeth and bite traces show a broad, opportunistic diet.
