对德国上侏罗统索恩霍芬石灰岩的翼龙化石的测量数据和形态学研究进行统计分析，揭示了翼龙种群的季节性重复采样导致的年分类的存在。Rhamphorhynchus的年级以前被命名为单独的物种。翼手纲标称种的年级相似，表明某些翼手纲种的大小级也被命名为单独的种或属。将名义上的物种集中起来，将索恩霍芬的翼龙动物群减少到少数大型物种，并表明一些长期以来关于翼龙进化的观点是不正确的。
Statistical analyses of measurement data and morphological studies of pterosaur fossils from the Upper Jurassic Solnhofen Limestone of Germany reveal the presence of year-classes resulting from repeated seasonal sampling of pterosaur populations. Year-classes of Rhamphorhynchus had previously been named as separate species. Similar year-classes of nominal species of Pterodactylus indicate that size-classes of some pterodactyloid species also had been named as separate species or genera. Lumping the nominal species reduces the Solnhofen pterosaur fauna to a small number of large species, and suggests that some long-held ideas about pterosaur evolution are incorrect.
