Otoconial material was obtained from a number of vertebrates to determine the CaCO3 polymorph present. Otoconia and otoliths from bony fish, amphibians, and reptiles are primarily aragonitic; those from birds and mammals are calcitic. This paper summarizes data from all other investigators as well as presenting new data, particularly pertaining to reptiles. The significance, if any, of the relationship between taxonomic group and carbonate polymorph remains an intriguing question.
从多种脊椎动物中获取耳石物质，以确定其中存在的碳酸钙多晶型物。硬骨鱼、两栖动物和爬行动物的耳石和听石主要是文石质的；鸟类和哺乳动物的耳石和听石是方解石质的。本文总结了所有其他研究者的数据，并展示了新的数据，特别是与爬行动物有关的数据。分类群与碳酸盐多晶型物之间的关系（如果存在的话）的意义仍然是一个有趣的问题。
