Fig. 4 in Divergent Morphology among Populations of the New Guinea Crocodile, Crocodylus novaeguineae (Schmidt, 1928): Diagnosis of an Independent Lineage and Description of a New Species

Fig. 4. Ventral cranial shape variation depicted using transformation grids with corresponding example specimen among drainages in Papua New Guinea. Solid points indicate consensus landmarks for all individuals, and lines extending from points indicate the extent (length) and direction of shape change exhibited by that classifier. Populations in northern drainages (i.e., Sepik; FMNH 14048; Crocodylus novaeguineae) exhibit an extended maxilla and reduced postcranial elements relative to southern populations from Lake Murray/Binaturi (C. halli; LSUMZ 44740) and the Aramia River (C. halli; USNM 211290), exhibiting strikingly shorter maxilla and enlarged postcranial elements.
