Greenland shark is about 1.28× longer by these reference values.
Greenland shark uses a 6.4 m upper reference, compared with 5 m for Squalicorax. 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
Greenland shark is represented by confirmed to about 6.4 m / 21 ft; Squalicorax by estimated to about 5 m / 16 ft. Age and upper mass involve uncertainty; length is better documented. Body length and ecology are reconstructed from incomplete fossil evidence.
Bite evidence
Greenland shark: TuffShark found no defensible species-level bite-force estimate to display. 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
The age estimate is extraordinary; a dependable bite-force figure is not available. Serrated teeth and bite traces show a broad, opportunistic diet.
