Molecular dating of 30 duplicated-gene pairs places teleost 3R before the study's crown-teleost interval and is compatible with delayed rediploidization.

Molecular models fitted to 30 teleost ohnologue pairs estimated the 3R whole-genome duplication at 286.18–267.20 Ma and crown Teleostei at 254.36–234.16 Ma, making 3R older by 12.84–52.02 million years; both intervals are model outputs, not fossil first appearances or instantaneous observations.
