Composition and age of the Daohugou hymenopteran (Insecta, Hymenoptera = Vespida) assemblage from Inner Mongolia, China [PDF]

open access: yesPalaeontology, 2004
Hymenopteran fossils from Daohugou, Inner Mongolia, China are assigned to 17 families. These include, in decreasing order of importance, Ephialtitidae, Xyelidae, Siricidae, Xyelydidae, Anaxyelidae, Karatavitidae s.l., Mesoserphidae, Megalyridae and Praeaulacidae. Analysis of the taxonomic composition suggests that the assemblage is of Mid Jurassic age.
