A large eagle (Aves, Accipitridae) from the early Miocene of Panama

We report the first Tertiary bird fossil from Central America, an ungual phalanx from a large, unknown genus and species of Accipitridae from the early Miocene Centenario Fauna, Panama. This specimen provides another example of a Neogene bird from North and Central America with its possible closest living relatives occurring today in Africa. In contrast, there is no evidence of African affinities among the reptile or mammal fossils from the Centenario Fauna.我们报道了中美洲发现的首例第三纪鸟类化石：一件来自巴拿马早中新世森特纳里奥动物群（Centenario Fauna）的大型未知属种鹰科（Accipitridae）爪趾骨（ungual phalanx）。该标本为北美与中美洲的新近纪鸟类提供了又一例证，其现存最近的疑似亲缘类群现今分布于非洲。与之形成鲜明对比的是，森特纳里奥动物群的爬行动物与哺乳动物化石中，未发现任何具有非洲亲缘关系的证据。
