Figure 10 in Scelidosaurus harrisonii (Dinosauria: Ornithischia) from the Early Jurassic of Dorset, England: biology and phylogenetic relationships

Figure 10. Scelidosaurus. Diagrammatic longitudinal section through the skull showing an attempted reconstruction of the nasal passage. The latter is shown floored anteriorly by a connective tissue sheet that forms a soft secondary palate that spans the gap between opposing maxillae and was probably attached sagittally to the ventral margin of the vomers. The epivomers are interpreted as sheet-like ossifications that form within the connective tissue that roofs the nasal passage; these bones are sutured to the dorsal edges of the vomers (Norman, 2020a). Abbreviations: Epi, epivomers; Mx, maxilla; np, nasal passage; ol.b, olfactory bulb; Pt, pterygoid; sp, soft palate. Arrows indicate air flow. Dark tone – bones in section. Pale tone approximate shape of the nasal passage.
