Figure 9. A in Evolutionary history of the devilrays (Chondrichthyes: Myliobatiformes) from fossil and morphological inference

Figure 9. A: Probable evolution of toothed jaw in mobulids, compared to sister groups of Myliobatidae (Myliobatis) and Rhinopteridae (Rhinoptera). Except for the living taxa, layout of teeth and number of tooth files were artificially reconstructed based on tooth morphologies and phylogenetic relationships performed on isolated teeth (number of tooth files and scales were not respected between taxa). B, Phylogenetic relationships from Fig. 8B constrained by the fossil record of Mobulidae (see text). Vertical bar, stratigraphical occurrences; dashed bar, uncertain records.
