Taxonomic remark Described as spore of fossil land plant (and treated as Sporae dispersae by subsequent authors), however reassigned to Acritarcha by Navidi-Izad et al., 2022 (no evidence for land plant origin). These aithors state: The biological affinity of these taxa [i.e., Virgatasporites and Attritasporites] remains uncertain. They are clearly spore-like microfossils, and in younger sediments they would have been identified and classified as cryptospores. However, there is so far no evidence for a biological affinity and a relationship to the embryophyte lineage. Therefore, both taxa must be classified as incertae sedis, i.e. as acritarchs, that are defined as organic-walled microfossils of unknown biological affinity. [details]
