New dragonflies from the lower Cenomanian of France enlighten the timing of the odonatan turnover at the Early – Late Cretaceous boundary

Three early Cenomanian Odonata are described from France (Jaunay-Clan locality, Vienne), i.e. the aeshnoid Galloliupanshania incompleta gen. et sp. nov. in the Liupanshaniidae, the libelluloid Gallophlebia magnifica gen. et sp. nov. in the new family Gallophlebiidae closely related to the Early Cretaceous Araripephlebiidae, and Gallostenophlebia incompleta gen. et sp. nov., as the youngest record of the clade Stenophlebioptera: Stenophlebiidae. Gallophlebia is a new case showing the high diversification of the libelluloid clade during the Cretaceous, while Gallostenophlebia corresponds to one of the last “survivors” of the odonatan ancient lineages in relation to the faunistic turnover around the Early–Late Cretaceous boundary.
