The fossil record of ibises is largely incomplete and very patchy. In this sense, the early record of ibises remains poorly documented, being represented by an isolated tibiotarsus from the Eocene of Myanmar (Stidham et al. 2016), and the enigmatic genus Rynchaeites from the Middle Eocene of Germany and Denmark (Mayr & Bertelli 2011). In South America and Antarctica, the oldest records correspond to the Lower Miocene Protibis cnemialis Ameghino 1891 (Tonni, 1980), and an indeterminate Late Eocene ibis-like bill from Antarctica (Jadwiszczak et al. 2008). The latter specimen was originally described by Jadwiszczak et al. (2008) who tentatively ascribed the bill to Threskiornithidae. If correctly identified, the specimen would constitute the oldest record of the clade for the Southern Hemisphere. Fil: Agnolin, Federico Lisandro.
