Palaeotis weigelti (lat.) Is a fossil species of flightless birds of the ostrich family, the only one in the genus Palaeotis . A specific Latin name is given in honor of the German paleontologist (1890-1948), who was the first to find fossilia .

The bird is known from the Middle Eocene ( Lutetian age ) of Germany [1] . This long-legged, flightless bird was up to 1 m high [2] .

The species was described by tarsus and phalanx in 1928 by Lambrecht. The author of the description considered the bird an early bustard and called it Palaeotis (ancient bustard) [3] . In 1987, Hood and Hobold (Houde and Haubold) studied this specimen and came to the conclusion that it belongs to a rat-free bird and assigned it to the ostrich-like order [4] . Also, Hood and Hobold attributed to the view three samples that were stored in the Museum of the University. Martin Luther in Germany and was first described as Paleogrus geiseltalensis .

Hood and Hobold believe that Palaeotis is a basal ratite , isolating it in the monotypic family Palaeotididae , or, perhaps, the ancestor of modern ostriches. The version that the species occupies a basal position in ratites was supported by G. Mayr in 2009 [5] . The species may be associated with Remiornis , the alleged ratites from the Eocene of France.
