哺乳动物的鼻囊内形成多个波纹状软骨结构，最终发育为鼻翼。由于其复杂的衍生形态，蝙蝠鼻鼻翼的同源性一直存在高度争议和不确定性。追踪产前发育已被证明提供了一种解决同源性问题的方法。为了阐明蝙蝠鼻甲的同源性，我们对鼻囊的产前发育进行了迄今为止最全面的研究。使用扩散碘基对比增强计算机断层扫描（diceCT），我们详细研究了各种蝙蝠和非蝙蝠月牙兽的三维产前发育。我们发现先前被确定为“上颌鼻”的结构并不是真正的上颌鼻，而只是鼻前部的一部分。我们的研究结果也使我们能够追踪蝙蝠鼻鼻甲的进化史。甲骨结构在整体上具有可比性，表明翼足目动物保留了祖先月虎目动物的状态。雁翼目动物和鼻类动物的后鼻翼部缺失可能是通过趋同进化独立发生的。
Multiple corrugated cartilaginous structures are formed within the mammalian nasal capsule, eventually developing into turbinals. Due to its complex and derived morphology, the homologies of the bat nasal turbinals have been highly disputed and uncertain. Tracing prenatal development has been proven to provide a means to resolve homological problems. To elucidate bat turbinate homology, we conducted the most comprehensive study to date on prenatal development of the nasal capsule. Using diffusible iodine-based contrast-enhanced computed tomography (diceCT), we studied in detail the 3D prenatal development of various bat species and non-bat laurasiatherians. We found that the structure previously identified as “maxilloturbinal” is not the true maxilloturbinal and is only part of the ethmoturbinal I pars anterior. Our results also allowed us to trace the evolutionary history of the nasal turbinals in bats. The turbinate structures are overall comparable between laurasiatherians and pteropodids, suggesting that pteropodids retain the ancestral laurasiatherian condition. The absence of the ethmoturbinal I pars posterior in yangochiropterans and rhinolophoids has possibly occurred independently by convergent evolution.
