Mongolbittacus
Mongolbittacus is an extinct genus of hangingfly in the family Bittacidae and containing a single species Mongolbittacus daohugoensis. The species is known only from the Middle Jurassic Jiulongshan Formation, part of the Daohugou Beds, near the village of Daohugou in Ningcheng County, northeastern China. History and classification Mongolbittacus daohugoensis is known only from one fossil, the holotype, specimen number "NIGPAS 133709". The specimen is composed of an almost complete female specimen which is preserved as a two dimensional compression fossil in a well cemented calcareous grey siltstone. The fossil was recovered from outcrops of the Jiulongshan Formation exposed near Daohugou by Di-Ying Huang. The type specimen is currently preserved in the geology collections housed in the Nanjing Institute of Geology and Palaeontology, located in Nanjing, China. Mongolbittacus was first studied by Julián F. Petrulevicius of the Muséum national d'histoire naturelle in Paris, France, Di-Ying Huang of 2Nanjing Institute of Geology and Palaeontology, and Dong Ren of Capital Normal University in Beijing. Their 2007 type description of the genus and species was published in the journal African Invertebrates. The generic name was coined by Petrulevicius, Huang and Ren from a combination of "Mongol", a reference to the region of discovery; and
