Short summary
The objective was to investigate inner ears and in particular the morphology of the cochlea of fossil and Recent baleen whales to reconstruct the occurrence of low-frequency hearing. Our results of cochlear shape analysis indicate that very low-frequency hearing appeared in the middle Miocene, and infrasonic hearing had evolved by the late Miocene. Cochlear coiling shape is suitable for estimating hearing limits in whales, closely approximated by cochlear length times number of cochlear turns.
