在中新世中期至晚中新世早期，整个欧亚大陆的水鸟群落发生了显著的重组，原始和灭绝的鸭类（如Mionetta）被更多的衍生形式所取代，包括现存的属。然而，在这一关键时期，人们对欧亚水鸟的多样性及其古生物地理学知之甚少。特别是，中新世中期的大型鸭以鲜为人知的分类群为代表，包括来自西欧和中欧的Anas sansaniensis和来自蒙古西部的Chenoanas deserti。我们报告了来自蒙古、东西伯利亚和中国的新的地理分布广泛的藜属标本，其中包括一个新种，Chenoanas asiatica sp. nov.，并允许承认欧洲的“Anas”sansaniensis是Chenoanas的成员。我们描述了最古老的遗骸Chenoanas sansaniensis从西伯利亚东部，这支持了向西扩散或范围扩大这组鸭子在中新世，以前建立的许多欧亚哺乳动物的地理亲缘关系。这些数据也支持了越来越多的证据表明，西伯利亚的鸟类动物群在中中新世气候适宜期与欧洲的相似。我们的数据表明，广泛的欧亚分布（超过8000公里）和Chenoanas属内的中新世晚期早期至中期的更大的多样性。Chenoanas的系统发育分析表明，它可能是Anatini的原始成员，因此不属于已灭绝的硬尾鸭（Oxyura及其亲属）的基部辐射。Chenoanas的物种可能不是专门的潜水员。
A notable reorganization of the waterfowl communities apparently took place across Eurasia during the middle to early late Miocene, when primitive and extinct anatid taxa (e.g. Mionetta) were replaced by more derived forms, including extant genera. However, little is known about the diversity of Eurasian waterfowl and their palaeobiogeography during this critical interval. In particular, larger ducks of the middle Miocene are represented by poorly known taxa including ‘Anas’ sansaniensis from western and central Europe and Chenoanas deserti from Western Mongolia. We report new geographically widespread specimens referred to Chenoanas from Mongolia, eastern Siberia, and China that include a new species, Chenoanas asiatica sp. nov., and allow for recognition of the European ‘Anas’ sansaniensis as a member of Chenoanas. We describe the oldest remains of Chenoanas sansaniensis from eastern Siberia, which supports a westward dispersal or range expansion of this group of ducks during the Miocene, comparable to the previously established biogeographical affinities of many Eurasian mammals. These data also support a growing body of evidence that avian faunas of Siberia were similar to European ones during the Middle Miocene Climatic Optimum. Our data indicate a wide Eurasian distribution (more than 8000 km) and a greater diversity within the genus Chenoanas during the late early to middle Miocene. The phylogenetic analysis of Chenoanas suggests that it may be a primitive member of Anatini, and thus does not belong to the basal radiation of extinct relatives of stiff‐tailed ducks (Oxyura and its relatives). Species of Chenoanas were probably not specialized divers.
