Otodus obliquus is about 1.28× longer by these reference values.
Otodus obliquus uses a 9.1 m upper reference, compared with 7.1 m for Megamouth 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
Megamouth shark is represented by reported to about 7.1 m / 23 ft; Otodus obliquus by estimated to about 9.1 m / 30 ft. Sparse specimens make a true maximum difficult to establish. Soft-body dimensions are inferred from teeth and living analogues.
Bite evidence
Megamouth shark: This filter feeder lacks a comparable maximum-bite study. 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
Known from relatively few encounters, it still carries major uncertainty. It belonged to the megatooth lineage that later produced megalodon.
