Skeleton of P. pacificus in lateral view, from Tyler et al. (2003), California Academy of Sciences CAS 38,404, 96 mm SL, showing landmarked bones and landmark locations. (A) Drawing of the entire skeleton of P. pacificus showing the positions of the landmarked bones. (B) Landmarks 1–8 of the upper jaw (premaxilla and maxilla). (C) Landmarks 9–16 of the lower jaw (dentary and anguloarticular). (D) Landmarks 17–23 of the suspensorium (symplectic, hyomandibula, and preopercle). All drawings are modified after Tyler et al. (2003). For definitions of specific landmarks, see Table 1. The individual bones are as follows: anguloarticular, yellow; dentary, green; hyomandibula, violet; maxilla, red; premaxilla, purple; preopercle, pale blue; and symplectic, black.
