Figure 10. Internal anatomy of the mouth, lip, and pharynx regions of various vertebrates from lateral view, mostly as midsagittal sections. A–C, living jawless fishes; D, schematic drawing of a jawed fish; E–G, jawless fossil ostracoderms. F, the osteostracan, shows two alternate reconstructions of the unpreserved parts of the branchial arches (F2, F3) with (F3) being the one I favour. (A and D) are redrawn from Mallatt (1996); (C) from figure 98 in Marinelli & Strenger (1956); (E) is Poraspis Kiaer, 1930 and (G) is Duyunolepis Pan & Wang, 1982 (?), both from Janvier (2008); (F1) is Norselaspis Janvier, 1981 from figure 51A in Janvier (1985); and (F2) is Scolenaspis from figure 14B in Janvier (1985) and figure 3 in Long et al. (2010).
