Otodus obliquus is about 1.42× longer by these reference values.
Otodus obliquus uses a 9.1 m upper reference, compared with 6.4 m for Greenland 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
Greenland shark is represented by confirmed to about 6.4 m / 21 ft; Otodus obliquus by estimated to about 9.1 m / 30 ft. Age and upper mass involve uncertainty; length is better documented. Soft-body dimensions are inferred from teeth and living analogues.
Bite evidence
Greenland shark: TuffShark found no defensible species-level bite-force estimate to display. Otodus obliquus: No species-specific model 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
The age estimate is extraordinary; a dependable bite-force figure is not available. It belonged to the megatooth lineage that later produced megalodon.
