The majority of enigmatic palynomorphs, which are not clearly attributed to miospores or extant protistan groups such as specific algal groups (e.g. prasinophycea, zygnematacea), are usually assigned to the Group Acritarcha. Acritarchs are defined as palynomorphs of unknown biological affinities. Although...
