一个几乎完整的跗跖骨，产于始新世中期的Silica South，Sperrgebiet，纳米比亚，被认为是鸡形目。这是非洲最早的记录。它属于一个干组鸡形和不同的最近的家庭。并与美洲中生代鸟类、欧洲和美洲的鸡亚科、栎亚科和拟步甲科进行了比较。因为标本是一个孤立的骨头，近端受损，我们不认为它属于一个家庭，但很明显，它代表了一个新的属和种的鸡形鸟，我们命名为Namaortyx sperrgebietensis。
An almost complete tarsometatarsus from the middle Eocene locality of Silica South, Sperrgebiet, Namibia, is attributed to the order Galliformes. This is the earliest record of the order in Africa. It belongs to a stem group galliform and differs from the Recent families. It is compared with Mesozoic birds from America, and Gallinuloididae, Quercymegapodiidae and Paraortygidae from Europe and the Americas. Because the specimen is an isolated bone, damaged proximally, we do not attribute it to a family, but it is clear that it represents a new genus and species of galliform bird, which we nameNamaortyx sperrgebietensis.
