FIGURE A3. States of denticle-based characters. A. Mid-crown denticles on the distal carina of an isolated tooth of Carcharodontosaurus saharicus (UC unlabelled) in lateral view showing the asymmetrically convex (char. 88:1) and parabolic (char. 90:0) margin of subquadrangular (char. 92:0) and apically inclined (char. 96:1) denticles, as well as a narrow interdenticular space (char. 103:0). B. Mid-crown denticles on the distal carina of an isolated tooth of Afrovenator abakensis (UC unlabelled) in lateral view showing the symmetrically convex (char. 88:0) and semi-circular (char. 90:2) margin of horizontal subrectangular (char. 92:1) denticles, perpendicular to mesial margin (char. 96:0), as well as a narrow interdenticular space (char. 103:0). C. Distal denticles of the fourth left maxillary tooth of Eodromaeus murphi (PVSJ 561) in lateral view displaying the mid-crown denticles vertically subrectangular in shape (char. 92:2) and having a convex external margin (char. 90:0) on the distal carina. D. Third left maxillary tooth of Scipionyx samniticus in lateral view displaying an unserrated mesial carina (char. 76:1), mid-crown denticles vertically subrectangular in shape (char. 92:2) and having a flattened margin (char. 90:1) on the distal carina, and a serrated distal carina extending well-beneath the crown apex (char. 102:1). E. Mid-crown denticles on the distal carina of an isolated tooth belonging to an indeterminate abelisaurid (MUCPv 482) in lateral view showing apically hooked denticles (char. 88:2) with a parabolic margin (char. 90:0), subquadrangular in shape (char. 92:0) and apically inclined (char. 96:1) from the distal margin, as well as a narrow interdenticular space between the denticles (char. 103:0). F. Mid-crown denticles on the distal carina of the third right premaxillary tooth of Eoraptor lunensis (PVSJ 512) in lateral view showing the apically hooked denticles (char. 55:2). G. Basal and mid-crown denticles on the distal carina of an isolated tooth of Troodon formosus (DMNH 22837) in lateral view showing subquadrangular (char. 92:0), apically hooked and strongly variable in size (char. 88:2) denticles, apically inclined (char. 96:1) from the distal margin, as well as a broad interdenticular space (char. 103:1) between them. H. Apical denticles on the mesial carina of an isolated tooth of Acrocanthosaurus atokensis (SMU 74646) in lateral view showing the subquadrangular (char. 91:1) and apically inclined (char. 95:1) denticles with a flattened margin (char. 89:1). I. Apical denticles on the mesial carina of an isolated lateral crown belonging to Megalosaurus bucklandi (NHM R234, tooth in matrix) in lateral view showing the apically inclined (char. 95:1) and biconvex denticles (char. 94:1). J. Mid-crown denticles on the distal carina of the ninth right maxillary tooth of Allosaurus fragilis (AMNH 851) in lateral view showing the symmetrically convex (char. 88:0), horizontal subrectangular (char. 92:1) and apically inclined (char. 96:1) denticles, as well as the broad interdenticular space (char. 103:1). K. Mid-crown denticles on the distal carina of an isolated tooth of Suchomimus tenerensis (MNN G73-3) in lateral view showing the serrated carina (char. 78:0) with minute denticles (char. 86:0) of irregular size along the carina (char. 93:1) and a veined enamel texture (char. 117:2). L. Distal carina at mid-crown in an isolated tooth of Spinosaurus aegyptiacus (MSNM V6422) in laterodistal view showing an unserrated carina (char. 78:1) and a deeply veined enamel surface texture (char. 117:2) curving basally in the vicinity of the carina (char. 118:1). M. Distal carina at mid-crown of a maxillary tooth of Irritator challengeri (SMNS 58022) in lateral view showing an unserrated carina (char. 78:1) and the smooth enamel surface texture (char. 117:0).
