Striking case of convergence — Alleged marine gastropods in Cretaceous Burmese amber are terrestrial cyclophoroids. Comment on Yu et al.

摘要

<br/>Yu et al. (in press) recently described two new species of gastropods from the Cretaceous Burmese amber and attributed them to the marine family Epitoniidae. A close inspection of the images provided by Yu et al. indicates however that the species in question do not belong to that family or any marine gastropod group. In contrast, the two species are attributed here to the terrestrial operculate family Pupinidae (Cyclophoroidea) and tentatively to the genus Pseudopomatias. We briefly review the fossil record of the Cyclophoroidea and Pupinidae and discuss implications of the present revision. After all, Pseudopomatias? lyui (Yu, Wang and Jarzembowski) and P.? zhuoi (Yu, Wang and Jarzembowski) belong to the oldest members of the Pupinidae.
