Alaskan Palaeogene insects: a challenge for a better knowledge of the Beringian 'route' (Odonata: Aeshnidae, Dysagrionidae)
International audience Four ‘routes’, Beringian, De Geer, Thulean and Turgai Strait, are currently considered to explain Cenozoic continental interchanges between Eurasia and North America. These ‘routes’ had a crucial importance for vertebrates and insects. While vertebrates are not infrequent in t...

Here we describe the first two Paleocene–Eocene insects from the Chickaloon Formation in Alaska, viz. Basiaeschna alaskaensis sp. nov., the first accurate fossil of this extant Nearctic aeshnid genus, and a representative of the extinct damselfly family Dysagrionidae, distributed in the Palaeogene of Eurasia and North America. These fossils provide direct evidence of the role of Beringia as a land bridge for insects during the Palaeogene. They are also evidence for a warm temperate climate in Alaska during this period of global warmth.
