Figure 21 in Comparative osteology and phylogenetic systematics of fossil and living bony-tongue fishes (Actinopterygii, Teleostei, Osteoglossomorpha)

Figure 21. Infraorbital bones of Elops and osteoglossomorphs showing different numbering strategies employed by Nelson (1969), Li & Wilson (1996a), and the present study. Nelson's and Li & Wilson's numbering systems are given anterior to posterior, and distinct elements are separated by commas. All are redrawn from those illustrated by Nelson (1969) except for †Lycoptera, which is from Jin et al. (1995) (Nelson did not illustrate †Lycoptera in his study). Black dots indicate position of the neuromast organ(s) associated with each element.
