Further enlargement of the cochlea, Nancy Simmons has established an association of morphological criteria in cranial capacity testifying écholocatrice (enlargement of the cochlea, connection stylohyale-os tympanique, morphology stylohyale [paddle-like bifurcant to the top of the skull] or morphology of the orbital process of the malleus [not decisive criterion])
Zaidi utvidgningen ya cochlea, Nancy Simmons imeanzisha muungano wa vigezo kubadilika kwa maumbile katika uwezo ya fuvu kushuhudia écholocatrice (utvidgningen ya cochlea, uhusiano stylohyale-os tympanique, morphologie du stylohyale [paddle-kama bifurcant juu ya fuvu] au maumbile ya mchakato wa orbital malleus [si maamuzi kigezo])
