Cherevychnavis umanskae

Quick answer

Holotype. An almost complete left coracoid, NMNHU-P, no. 45 - 2453 (Figs. 1 – 6), deposited at the National Museum of Natural History at the National Academy of Sciences of Ukraine, Kyiv, Ukraine. Referred material. Proximal left humerus with shaft, NMNHU-P, no. 45 - 2452 (Figs. 7 – 10), deposited at the National Museum of Natural History at the National Academy of Sciences of Ukraine, Kyiv, Ukraine. It is likely that the humerus represents the same extinct taxon as the holotype because the two bones were found at the same site, they match in size, and can be assigned to the same suborder Charadrii sensu Paton et al. (2003), but because they were not found in articulation, it cannot be conclusively demonstrated that they belong to the same species. Type locality and horizon. Cherevychne 3, located on the left banks of Khadzhibey Estuary, between the villages of Cherevychne and Morozovka (Bilyayivka District, Odessa Region, Ukraine; 46 ° 38 ′ 35 ″ N, 30 ° 37 ′ 12 ″ E); late Miocene, lower part of the Mammal Neogene Zone 12 (MN 12) of the late Miocene (Tortonian), approximately 8 - 7.5 mya.
