Short summary
Skeletal morphology is the traditional way to classify living and fossil silicoflagellates (siliceous phytoplankton); however, recent studies have demonstrated that measurements of skeletal parts can also provide important information about evolution and skeletal development. In the present study, a 2-D morphometric programme was modified in order to study the taxonomic confusion within a fossil species complex of the genus Corbisema. The results show that two species can be clearly separated.
