The fossil record of Mesozoic neornithine birds is restricted to the Upper Cretaceous (Campanian, Maastrichtian) from America, Europe, Asia, and Antarctica (Hope, 2002). Most of the Cretaceous neornithines recorded at present, correspond to aquatic groups (e.g., Charadriiformes, Anseriformes; Olson and Parris, 1987; Elzanowski, 1995), but a few terrestrial forms were also documented ( e.g. , Psittaciformes, Galliformes, and probably Paleognathae; Stidham, 1998; Hope, 2002). This diversity of taxa constitutes the best available evidence to discuss the timing and branching sequence of clades of modern birds.
