Figure 3. - The upper jaw dentition in three different life stages of Eretmodus cf. cyanostictus (lineage A) (A-C) (11.4 mm SL, 23.4 mm SL and 51.0 mm S.L., resp.) and magnifications of an individual tooth in the respective dentition (A'-C'). D: Lower jaw of the specimen used in (B, B'), showing monocuspid teeth, formed extramedullary (arrowhead), at the end of a row of spatulate teeth, displaying intramedullary replacement. D': Detail of the last spatulate tooth (arrow) showing replacement tooth forming intramedullary below (asterisk). Scale bars: A, B', D' = 100 µm; A' = 15 µm; B, C = 500 µm; C', D = 200 µm.
