FIGURE 34. 3D in A reappraisal of the cranial and mandibular osteology of the spinosaurid Irritator challengeri (Dinosauria: Theropoda)

FIGURE 34. 3D renderings of left mandibular elements of Irritator challengeri (SMNS 58022). A, lateral view; B, dorsal view; C, medial view. Abbreviations: addf, adductor fossa; an, angular; d, dentary; glf, glenoid fossa; lss, lateral surangular shelf; manf, mandibular fenestra; mhp, medial hook process; mics, medially inclined coronoid shelf; pra, prearticular; rap, retroarticular process; sur, surangular. Note that different bones are rendered in different colours, and that bone labels are in bold. Also note that the articular is fused with the surangular and thus segmented in a joint model with that bone.
