Comparative Anatomy of the External and Middle Ear of Palaeognathous Birds (Advances in Anatomy, Embryology and Cell Biology) $29.60 This volume presents a broad comparative anatomical approach towards the functional morphology of the middle ear of palaeognathous birds (ostrich, rhea, tinamous, emu, cassowary, kiwi) and basal neognathous birds. It presents the most complete and thoroughly studied source of material on this field. For the first time it became possible to develop exact images of “non-structures” like the air-fill… |
