Comparison of jaw apparatuses of Andiprion paxtonae (family unknown; depicted after Hints et al., 2017), Protarabellites luztejadae sp. nov. (Ramphoprionidae) and Protarabellites staufferi (Ramphoprionidae; depicted after Eriksson, 2001). Left and right first maxillae are also depicted from the ventral side (facing the myocoele opening, a diagnostic character for the new species). The maxillae with the dashed line are not known and they are only tentatively reconstructed according to better-known related species. MIL= first left maxilla, MIR= first right maxilla, MIIL= second left maxilla, MIIR= second right maxilla, bp= basal plate, cr= carriers, v= ventral view.
