A new genus and species of fossil hawker dragonfly, Parabaissaeshna ejerslevense gen. et sp. nov. (Aeshninae: Allopetaliini), is described from the Early Eocene Fur Formation (Mo-clay) of the island of Mors, northern Denmark. Its position among traditional "gomphaeschnine" dragonflies is discussed, and it is attributed to the tribe Allopetaliini as close relative to the Cretaceous genus Baissaeshna, documenting the survival of this lineage through the K-Pg mass extinction. The Recent genus Boyeria and the Eocene genus Anglogomphaeschna are also transferred to Allopetaliini.
一种新的化石食虫蜻蜓属及物种，即埃耶斯莱文氏副拜氏蜓（Parabaissaeshna ejerslevense gen. et sp. nov.）（蜓科：异花蜓族），是从丹麦北部莫尔斯岛的始新世早期富尔组（莫粘土）中描述出来的。文中讨论了它在传统“ gomphaeschnine”蜻蜓中的位置，并将其归为异花蜓族，作为白垩纪拜氏蜓属的近亲，证明了该谱系在白垩纪-古近纪大灭绝事件中的存活。现存的博耶蜓属和始新世的盎格鲁gomphaeschna属也被归入异花蜓族。
