FIGURE 2.

Skeletal analysis of the secondary palate at post-hatching stages of chameleon by microCT. Whole mount cranial skeleton from palatal view displays post-hatching development of the palate-forming bones in chameleon (A–C). Transversal sections of microCT scans reveal developmental and morphological changes of the palate-forming bones in three different planes during post-hatching development. Cross sections through the palatine bones (red lines in whole mount skulls) (D–F). Cross sections of the junction between the palatine and pterygoid bones (green lines on whole mount skulls) (D′–F′). Cross sections of the pterygoid, ectopterygoid, and jugal bones (blue lines on whole mount skulls) (D″–F″). White arrows in (F,F′) show contact of soft palatal tissues. ec, ectopterygoid; j, jugal; mx, maxillary bone; pl, palatine bone; pt, pterygoid bone. Scale bar: cross sections 4 mm.
