"WebSphenolithus predistentus. Morphometric studies of the Reticulofenestra umbilicus-hillae group show that these cannot be subdivided into two different morphospecies. Based on differences in morphometry and stratigraphic ranges, the Oligocene Sphenolithus lineage appears to be the result of a combined anagenetic and cladogenetic evolution.
