uberon
Some species, like Amolops tormotus (Feng et al. 2006), have a cavity in front of the tympanic membrane which is considered to be an ear canal and thus an outer ear. (...) The ancestral lineage of amphibians separated from the mammalian lineage, approximately 350 million years ago, in the paleozoic era. Many of the important developments in the auditory systems emerged after the ancestral paths separated (Manley and Clack 2003). This implies that shared features, like the tympanic middle ear, developed independently in different vertebrate lineages.[uncertain][VHOG]
