Whale shark is about 1.26× longer by these reference values.
Whale shark uses a 12.2 m upper reference, compared with 9.7 m for Ptychodus. 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
Ptychodus is represented by recent reconstructions approach 9.7 m / 32 ft; Whale shark by well documented near 12.2 m / 40 ft. A body outline is rare; length estimates can change with new fossils. Exceptional historical lengths exist, but 12.2 m is a conservative comparison value.
Bite evidence
Ptychodus: Hard-prey specialization does not justify inventing a force number. Whale shark: Whale sharks filter feed; a comparable maximum bite-force study is not available.
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
Flattened crushing teeth—not knife-like teeth—defined this huge shark. The largest living fish is a filter feeder, so a predatory bite ranking would mislead.
