Figure 5 in The evolutionary radiation of modern birds (Neornithes): reconciling molecules, morphology and the fossil record

Figure 5. Cartoon depicting consensus phylogenetic relationships among Anseriformes ('waterfowl') (based on Livezey, 1997) (Presbyornithidae includes the taxa Presbyornis and Teviornis; see text for details) along with a selection of wellpreserved fossil taxa: A, holotype skull of Anatalavis oxfordi in lateral view from the Lower Eocene London Clay Formation (The Natural History Museum, London, Palaeontology Department Collections, BMNH PAL 5922) (see Dyke, 2001b); B, holotype coracoid of BMNH PAL 5922 in dorsal and medial views) (scale bars = 10 mm); C, holotype carpometacarpus of Teviornis gobiensis from the Late Cretaceous Nemegt Formation of Mongolia (Palaeontological Institute of the Russian Academy of Sciences, PIN 4499–1) in dorsal and ventral views (see Kurochkin et al., 2002). Scale bar = 10 mm.
