Otodus obliquus is about 4.5× longer by these reference values.
Otodus obliquus uses a 9.1 m upper reference, compared with 2 m for Frilled 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
Frilled shark is represented by about 2 m / 6.6 ft; Otodus obliquus by estimated to about 9.1 m / 30 ft. Deepwater records remain limited. Soft-body dimensions are inferred from teeth and living analogues.
Bite evidence
Frilled shark: No standardized maximum is available. 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
Its body plan looks ancient, but living frilled sharks are modern species—not unchanged fossils. It belonged to the megatooth lineage that later produced megalodon.
