Dimensions Of Holotype

Length: 14.5µm

Description

Very large ( >14.0µm) species of Obturolithus. The largest specimen observed is 26.0µm so far.

Remarks

The size of Dictioococcites perplexa Burns, 1975 is possibly miss-calculated. Moreover, it is invalid, according to ICN Art. 40.3, because two holotypes were cited.
