鹦鹉螺不适合作为模型生物来推断菊石的生物功能、胚胎发育或生命模式。对现有的形态学数据进行了简要回顾，并添加了分子数据，以讨论螺旋藻作为菊石类生物代表物的有用性。事实上，有许多形态学线索表明螺旋藻可能是研究菊石胚胎发育的有用模型生物。分子数据似乎支持这一假设。然而，无法检测螺旋藻的通用模型特征，因为例如螺旋藻和菊石之间的进食方式可能不同。
Nautilus is not suitable as a model organism to infer biological functions, embryonic development, or mode of life in ammonoids. A brief review of the available morphological data is given and molecular data are added to discuss the usefulness of Spirula as a biological proxy for ammonoids. Indeed, there are many morphological hints indicating that Spirula could be a useful model organism for approaching the embryonic development of ammonoids. The molecular data seem to support this hypothesis. However, a universal model character of Spirula cannot be detected as, e.g., the mode of feeding probably differs between Spirula and ammonoids.
