Nomenclatural note
Ovum was created for what was considered eggs of marine invertebrates, thus clearly under the ICZN and not subjected to invalidity as per Art. 20.2 of the ICN: "The name of a genus may not coincide with a Latin technical term in use in morphology at the time of publication unless it was published before 1 January 1912 and was accompanied by a species name published in accordance with the binary system of Linnaeus."
Later reclassifed as an acritarch, according to Fensome & al. (1998: 379, who erroneously considered Ovum invalid): "In giving the heading 'Ova hispida Lohm.', Eisenack (1931) was clearly referring to the inadmissible two-word, unhyphenated generic name Ovum hispidum (...) apparently proposed by Lohmann (1904). However, by giving citations such as 'Ovum hispidum longispinosum n. subsp.' it is clear that Eisenack (1931) considered Ovum to be a generic name and Ovum hispidum (plural: Ova hispida) to be a specific name. Ovum hispidum can thus be considered the single (and type) species assigned to Ovum by Eisenack (1931), a description being provided on his p. 110".
