Table 1 in Revision of 18 ichneumonid fossil species (Hymenoptera, Ichneumonidae) highlights the need for open nomenclature in palaeontology

Table 1. List of fossils treated and summary of taxonomic changes. Eleven subfamily and 12 generic classifications have changed (Xylonomus is variously treated as a subgenus or junior synonym of Xylonomus Xorides and is thus not included in this count).
