Quercymegapodiidae，原始galliforms类似于现代的megapodes，已被描述于法国Quercy的上始新世。它们也在巴西的上渐新世-下中新世被发现，以Ameripodius Alvarenga属为代表。本文报道了该属一新种，亚氏美洲足虫Ameripodius alexis sp. nov.来自法国中新世晚期的化石在大西洋两岸出现的同一属强调了南美洲和欧洲鸟类在第三纪早期的相似性。新的发现表明，类似的鸟类区系也存在于北美洲，并且可以为包括南美洲，北美洲和欧亚大陆的组定义一个特征性的分类群。然而，就目前所知，相同的鸟类区系并不存在于同时代的非洲鸟类区系中。
The Quercymegapodiidae, primitive galliforms resembling recent megapodes, have been described from the Upper Eocene of Quercy, France. They have also been identified in the Upper Oligocene–Lower Miocene of Brazil, where they are represented by the genus Ameripodius Alvarenga. A new species of this genus, Ameripodius alexis sp. nov., from the Lower Miocene of France, is described here. The occurrence of the same genus on both sides of the Atlantic Ocean emphasizes the similarities between South American and European avifaunas during the early Tertiary. New discoveries indicate that a similar avifauna was also present in North America, and that a characteristic association of taxa can be defined for the group that includes South America, North America and Eurasia. However, so far as is known, the same avifauna does not occur in contemporaneous African avifaunas.
