Evolutionary Trends of the Pharyngeal Dentition in Cypriniformes (Actinopterygii: Ostariophysi)
Figure 2
Examples of Cypriniformes dentitions obtained by microtomography and analysis of 3D reconstructions.
In each case, the dental formula and the tooth shape are indicated. 1: Danio rerio (Rasborinae); 2,4,5; spoon. 2: Carassius auratus (Cyprininae); 4; compressed. 3: Cyprinus carpio (Cyprininae); 1,1,3; molariform. 4: Epalzeorhynchos bicolor (Cyprininae); 2,4,5; spatula. 5: Gobio gobio (Gobioninae); 2,5(−5,3); spoon. 6: Scardinius erythrophtalmus (Leuciscinae); 3,5; saw. 7: Xenocypris yunnanensis (Cultrinae); 2,3,5(−6,3,2); compressed. 8: Misgurnus anguillicaudatus (Cobitidae); 14–16; conical. 9: Ictiobus cyprinellus (Catostomidae); 55; conical. A: occlusal view; B: ventral view; C: dorsal view. Except for 8 and 9. A: anterior view; B: posterior view. For Cyprinoidea plates, teeth are painted according to the following: (i) teeth on the left side are all painted according to their row: red for ventral row, blue for mediodorsal row and yellow for dorsal row; (ii) teeth on the right side are painted only if their row displays a tooth number different from the left side (so that species displaying asymmetry are easily visible because of colours on the right half-bone).
