Squalicorax is about 1.41× longer by these reference values.
Squalicorax uses a 5 m upper reference, compared with 3.54 m for Zebra 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
Squalicorax is represented by estimated to about 5 m / 16 ft; Zebra shark by reported to 3.54 m / 11.6 ft. Body length and ecology are reconstructed from incomplete fossil evidence. Its very long tail adds substantially to total length.
Bite evidence
Squalicorax: Bite traces show feeding, not maximum force. Zebra shark: No standardized maximum is used.
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
Serrated teeth and bite traces show a broad, opportunistic diet. Juveniles have stripes; adults are spotted despite the common name.
